How Should Mariners Approach Deadline Four Games Under .500 Yet Still in Playoff Hunt?
The Mariners certainly know what they’re doing wrong after they dropped their latest series to the Los Angeles Dodgers on Thursday with a 6-2 loss.
“Yeah, it’s up to us,” Bryan Woo said after his five-run, five-inning losing outing. “The front office and coaches and everybody has put enough into the product on the field. It’s time for us to do something about it.”
But they don’t quite know how. The team has a consistent discipline issue, careening between lethargic defeatism and frantic efforts to arrest their decline. The failures of the latter cause the team to return to lethargy, and the cycle repeats on a near-nightly basis.
With this in mind, how should the Mariners approach the upcoming 2026 trade deadline? They have a few more days than they would otherwise have most years - with the deadline set for Aug. 3 - but the hour is fast approaching when they have to decide on tune-ups, changes, and deals.
The team is in an odd spot. It’s not a situation where they can reasonably go out and get one-year rentals like they did in 2025, but it’s also not a sell situation, either; they could very well still go on a run and make a splash in the playoffs. An intuitive approach for Seattle is to deal away upcoming free agents in exchange for longer-term options, but those sort of minor sales would have to be augmented by long-term options for the relevant team (say, a prospect). The M’s also have a bunch of starting pitchers, including near-MLB prospects, allowing them to trade from that pool to deepen other areas of the team.
One thing they cannot do is stand completely pat. Beyond that, however, it’s prudent to examine the attitudes that the Mariners might have about their trade deadline situation; there are lots of ways to skin a catfish, after all.
Five Mariners Homers Overcome Heavy-Hitting Dodgers in Chavez Ravine Thriller
The Mariners’ disastrous series against the Rangers finally put to rest the notion of the team as the AL West favorite, with a 52-55 record and a two and a half game deficit in the division with a month-long gauntlet fast approaching. What had been true for the whole season was now eminently evident to the entirety of the dugout: that both greater commitment and greater precision are needed in order to return to the playoffs, much less to the precipice of the pennant.
Iron, as they say, sharpens iron; who better to face than the two-time defending champion Dodgers? They immediately displayed why their offense is one of the best in baseball, working to quickly punish whatever Luis Castillo pitches leaked out over the plate. But the Mariners, needing a win to keep pace with the Rangers and Astros ahead of them, managed to put together a thrilling 7-6 victory on the backs of five home runs and some high-stress relief pitching.
It was the first Mariners win against the Dodgers since April 19, 2021. It was the first Mariners win in Dodger Stadium since June 28, 2009. To put it another way: the last time the M’s beat the Dodgers in the City of Angels, Rob Refsnyder was 18, Cal Raleigh was 12, Dominic Canzone was 11, and Julio Rodríguez was eight. Those were the four M’s to go deep on Tuesday.
Cal Raleigh and Julio Rodriguez hit a homer in the same game for the first time since April.
Before the season began, the duo of Rodríguez and Raleigh were projected to accrue between five and six wins above replacement (WAR) each. With 55 games left in the season, Rodríguez had 1.8 FanGraphs WAR (fWAR) and Raleigh 0.5, each reflective of injury-shortened years with significant struggles - especially in the case of Raleigh, who had a .165/.269/.300 slash line going into Tuesday.
The struggling catcher found himself on the IL for roughly a month-long stretch of time straddling May and June, but he appeared set to roar back on the scene after a homer-studded rehab assignment in Tacoma. That ended up being a mirage; Raleigh had a .170/.304/.277 slash line between his return on June 16 and the end of the Rangers series on July 27. The power stroke was especially absent, as he had just three homers during these 33 games.
Four Runs Still Out of Reach as Mariners Fall 4-3 to Guardians
The Seattle Mariners continue to eye franchise history - for the wrong reasons - as they tied the team record with 13 games in a row while scoring three or fewer runs in a 4-3 loss to the Cleveland Guardians on Saturday. Holding onto a half-game lead in the middling American League West, the Mariners need to decide if they want to build on last year's success or drift sheepishly back into mediocrity.
Even the most optimistic Seattle fans know the phrase “Same old Mariners.” It encompasses the feelings of a downtrodden fanbase that has only made the playoffs six times in their 50 years of existence. Despite having the greatest season in team history last year by reaching Game 7 of the American League Championship Series, most fans are already ready to chalk it up as a fluke given their team’s struggles this year.
The roster is not devoid of talent; quite the opposite actually. FanGraphs Playoff Odds still gives the M’s an 80.3% chance of making the postseason. The lineup still needs to wake up though, as this roster has shown that it cannot sleepwalk its way to winning the division.
The trade deadline is approaching. Changes need to be made. What can this SoDo squad do to get back on track?
Gilbert, Mariners Salvage Red Sox Matinee, Keep Heads Above Water
All wins are equal on the final sheet of standings at the end of the year, but not all these wins mean the same things when they are played. Some wins are triumphant jewels in the crowns of great streaks, others are dead cat bounces for a team plummeting into the gutter. The Mariners’ 3-1 win over the Red Sox on Sunday was neither of those, but it was the definitional salvaged game, turning what could have been a sweep to go under .500 on the summer solstice into a lost series and a 40-39 record with the halfway point nearly reached.
The offense, for the eighth straight game, didn’t impress, but the Mariners worked a win anyway thanks to an incredible start from a rebounding elite arm, a couple of timely hits, and a sharp bullpen. And yet the win may be pyrrhic, with another key player falling to the injury bug.
Logan Gilbert worked into the seventh and kept the Red Sox to a single run.
While the Mariners haven’t had everyone clicking at the same time, they have had the relative luxury of often getting a cold man hot once their hot man goes cold. While Emerson Hancock has seemingly taken a big step back over the past two outings, Logan Gilbert has finally settled into a real adjustment against the five-and-dive outings and long at-bats that had created them.
This adjustment has been quite simple and equally effective: instead of relying solely on his secondary pitches in favorable counts - a strategy that teams effectively countered by simply laying off the low sliders and buried splitters they would see time and time again - Gilbert has truly mixed things up with fastballs, curveballs, splitters, and sliders in these counts. This means, in the aggregate, that he is throwing the heater a lot more.
Mariners No-Hit Through 6, Late Comeback Comes Up Short in 6-2 Loss to Red Sox
Coming off a gratifying shutout victory against the Baltimore Orioles, the momentum slowed down for the Seattle Mariners on Friday night. Facing an underperforming Red Sox team limping into the Emerald City, Seattle looked primed to rattle off a win streak against a Boston squad fresh off suffering a sweep by the Toronto Blue Jays.
Boston had other plans however, capitalizing on poor pitching decisions, an inability to hit lefties, and a lack of bench depth, as the Sox punished the M’s mistakes at every turn to open the series with a 6-2 win at T-Mobile Park.
Julio Rodriguez homered in the ninth inning to drive in two runs, but it proved far too little, too late. Outside of the centerfielder’s blast, the Mariners had little to celebrate on Juneteenth as they donned their popular Steelhead jerseys, paying homage to the Negro League team that predates the M’s.
What went wrong in the Mariners’ latest defeat?
Mariners’ Tuesday Bombshells: Rotating Piggyback, Pereda Sent Down, Arozarena to IL
Tuesday ended in a solid 3-1 win for the Mariners at home against the Orioles, but a flurry of roster moves and decisions may have been even more hectic for the team than that night’s action. The team called Cal Raleigh back up to the MLB roster, announced a first-of-its-kind rotating piggyback, and had to call up a guy who had taken four total plate appearances above High-A ball in his entire career thanks to a seemingly bizarre lack of preparation on Randy Arozarena’s injury status.
Mariners general manager Justin Hollander, speaking with media Tuesday afternoon, noted the inordinate severity of the injury situation as compared to other bugs he had dealt with in his tenure with the team; he noted that Luke Raley and Josh Naylor were both dealing with issues and that Matt Brash, Carlos Vargas, and Cooper Criswell would be out until around the trade deadline. Brendan Donovan is set to start running work in the week, but these persistent injuries are not a good sign. This is especially true of Raley’s lower back tightness, given that similar injuries ended up shattering his 2025 season well after he was officially healed.
The mechanistic plan to have each of Seattle’s six starting pitchers rotate the piggyback amongst themselves is many things, but to use a judgmentally neutral term, it is unprecedented. It is also seemingly contradictory that the same organization that came up with a plan as intricate as a rotating piggyback also waited until a gameday to MRI Arozarena despite having a rest day to do so; had they done the simple thing of scheduling an earlier MRI, they would have been able to call Connor Joe back up as is clearly their long-term plan.
But what’s done is done, as bizarre as the events were. What should be made of these decisions, and what do they mean for the near future of the Mariners’ season?
Hand Injury Sidelines Crawford as Mariners Drop Detroit Opener
The ultimate meaning of Friday’s game in the Motor City will depend quite a bit on the health of J.P. Crawford: if he is out for a significant stretch of time (or if his abilities get all out of goose should he try to play through something serious), then an errant - it may have been Framber Valdez, but it certainly seemed to have been an accident in this case - full count sinker may end up being more pivotal than an otherwise unremarkable 7-3 loss would indicate. Should the Mariners recover to put some more wins back together and Crawford recover back to the way he had been playing, then the game might truly become a footnote.
Of course, if a veritable skid begins for the Mariners, with or without Crawford, then the momentum of Friday’s action may end up important for much larger reasons.
The M’s went back to familiar ways with runners in scoring position, with runs drying up in Detroit.
Friday was Valdez’ 20th career appearance and 18th start against the Seattle Mariners, during which he had gone 7-4 with a 3.50 ERA and 1.320 WHIP. The M’s, of course, were codivisional with Valdez during his eight years with the Astros, but the team he faced on Friday was one that had spent most of the year flailing against lefties.
Cole Young Walks Mets Off; Mariners Win Seventh Straight
A baseball club in Seattle is showing that when it rains, it pours. Through May 24, the team went 7-12 in one-run games and lost four out of five extra-innings contests. Since then, the M’s have won three of each, with all the luck falling their way even in games where they leave quite a lot on the table.
All three of those have been walk-off wins, each from the bat of a different Mariner. Monday’s hero in the end was Cole Young, but unlike the others, there was a notable uniqueness to his hit. During the game, 22 players had plate appearances on Monday night. Four had hit home runs, but other than Young, no hitter had found a patch of green grass or evaded the waiting glove of an opponent.
Mariners manager Dan Wilson smirked as he described his team’s “flair for the dramatic” after the game, the team’s second straight 3-2 10-inning victory. That was certainly an understatement, though the drama started with dueling lineup card moves between the managers.
Seattle tried to play coy with the lineup against the Mets opener, but the visitors got the hurling they sought.
For the first time all year, the Mariners faced a team going with the fabled “opener” strategy, with listed starter Austin Warren being a bullpen arm tasked with beginning the game. That setup has its issues, but so had Manaea; the once-blockbuster signing entered the game with a 5.56 ERA entirely as a relief arm.
M’s Complete 22-4 Sweep of A’s with 9-1 Blowout, Take First Place in AL West
Despite still being a game back of .500, the Mariners are in first place in the AL West. In one sense, it doesn’t matter; a man once said that you should check the standings once on June 1 and every day starting July 1. But in another sense, the series was massive.
“Yeah, I think so,” said Mariners starter Logan Gilbert when asked if the series (in which they outscored their opponents by 18 runs) was their most complete of the season. “To go out there and prove it like that, and everybody steppin’ up at different times, it says a lot about the team.”
For the first time since sweeping the Astros at home back in April, the M’s cobbled together three consecutive complete wins. From the first inning onward on Wednesday afternoon, Seattle held a watertight lid on a team that had come into the series scoring 4.8 runs per game in their home ballpark. Julio Rodríguez put a bow on the whole thing with a three-run jack in the eighth, but the final outcome was not in doubt long before the 9-1 final score.
Rob Refsnyder got the Mariners started with a three-run homer, continuing an inchoate upturn.
The Mariners’ $6.25 million acquisition of platoon bat Rob Refsnyder hasn’t been a very productive signing despite the clear pedigree of production against lefties over his previous four seasons. With a horrific .113/.195/.197 slash line going into Wednesday’s game, it appeared that his time with the Mariners was nearing an ignominious conclusion.
That may yet be true. But a glimmer of hope shone through in the first inning, as he built on a hit in Tuesday’s game with a loud 107.7 mile per hour bomb.
M’s Move Within Striking Distance of Division Lead with Win over A’s
Tuesday night was the first time the 2026 Mariners followed up a win of six or more run differential with a win of three or more run differential. Those benchmarks are largely meaningless in and of themselves, but they showed that the team finally managed to string together two largely complete victories, Tuesday’s a solid 4-1 win.
With a lead in hand for nearly the whole contest, the M’s did well to keep the powerful Athletics lineup off the board and away from any sort of comeback; not once after the first did the hosts have the tying run at the plate. But most of all, the team finally showed life against a side of the mound they have been vexed by for a grueling stretch of time.
The Mariners Jump-started their offense against a debutant Sacramento southpaw.
It’s no secret that the Mariners have been horrendous batsmen against left-handers, coming into the game with a .190/.277/.315 slash line against southpaws going into Tuesday’s game. The A’s sought to exploit this fact with quite the bold move: calling up lefty pitching prospect Gage Jump from Triple-A in order to be able to face the M’s on their weaker side.
It’s Time for Dan Wilson, Mariners to End Platoon Obsession
The Seattle Mariners began this season with a clear plan to cycle through several players. A “platoon” in baseball is defined as a “a managerial strategy where two players share a single defensive position, alternating starts based on the handedness of the opposing starting pitcher.”
For example, the Mariners signed Rob Refsnyder this offseason to mash against left-handed pitching. When Seattle faced a right-handed starter, Dominic Canzone and Luke Raley would be in the lineup with Refsnyder on the bench.
But after 55 games, now closer to the halfway point of the season than the season opener, it’s time to ditch this approach.
M’s Take Close, Stable Pitcher’s Duel to Begin Road Trip in Kansas City
The Mariners have seen games take wild courses in Kauffman Stadium over the past few years, but on Friday night, it was remarkably stable. Both teams struggled quite a bit at the plate, leading to a low-scoring pitcher’s duel, but one home run for the visitors led to Seattle taking a 2-0 lead and the M’s bullpen went all according to plan.
Logan Gilbert threw nearly six shutout innings, recovering from his seven-run disaster against the Padres.
The last time Logan Gilbert had gone out to the mound, he had thrown 21 of his 27 first pitches for strikes, yet the San Diego Padres jumped on them for seven runs in total. Gilbert threw 15 of 21 first pitches for strikes on Friday, yet he kept the opposing Royals scoreless.
Talking with the media before the game, manager Dan Wilson downplayed concerns that the Mariners’ strike-throwing had allowed hitters to sit on and ambush early strikes.
“We do attack the zone, we do want to get ahead, and I think it’s a different at-bat when you do,” Wilson said before Friday’s game. “I think the good always outweighs the bad when it comes to that.”
Of course, the devil is in the details. Looking at a map of these first pitches, with those against San Diego on the left and those against Kansas City on the right, there are a couple things that are clear.
Welcome to the Show: Colt Emerson Whacks Big Jack for First Career Hit, M’s Top White Sox 6-1
On Sunday morning, the Mariners brass was faced with a decision. Brendan Donovan had re-injured his groin during a game against the Astros, and with Leo Rivas’ struggles continuing unabated and an unclear timeline for Patrick Wisdom (though he was evidently taken off the IL the following day), the time was arriving for 20-year-old top prospect Colt Emerson. At least, that’s the decision that the front office made.
“We think he’s the best option,” Hollander said about Emerson on Sunday. “This period will give him some runway; this is not a 15 at-bat or a 20 at-bat tryout to see if he’s capable of taking the job and running with it for the rest of the year.”
One key homer does not a good player make, but when Emerson sent a low liner a hair’s breadth above the yellow crown of T-Mobile park’s right field wall in the bottom of the eighth - a shot that put the M’s up by the 6-1 score that would prove final - Seattle got a glimpse of things that may be.
Colt Emerson’s first major league hit was a three-run homer to turn a close lead into a comfortable one.
When Emerson went up to the dish, the momentum of the game had left a growing pit in many stomachs across the Northwest. Seattle had scored one run on a Julio Rodríguez bomb in the first, another on a third inning Randy Arozarena RBI double that was more memorable for what happened between second and third, and a run-scoring Josh Naylor single in the sixth.
But despite an electric double steal growing the inning into a second-and-third, one out opportunity, neither Cole Young nor Emerson had cashed in, and a homer followed by a bunch of stranded traffic had put the wind at the White Sox’ back.
Two Electric Homers Give Mariners Comeback Win against White-Hot Braves
Home runs are thrown, not hit. That is an adage that holds up among the best and most consistent hitters in the game, who take what is given to them and do the most they can with it, whether that means lining one the other way or launching it in the air. When a hitter tries to force a home run on a pitch that won’t allow it, there are a whole lot of outcomes like strikeouts and rolled-over grounders that end up much worse for the hitter.
Paradoxically, this also means that home runs are determined by the hitter. Pitchers who allow fly balls will allow home runs, but it’s up to the hitter to put that swing on it when it comes.
A lot of hitters tried to hit homers on Monday night in Seattle as the Braves took on the Mariners, the visitors white-hot and the home crew struggling. While nobody could get it done with the bases loaded, six hits left the yard: four for Atlanta and two for Seattle, but the M’s got theirs with men on base and won 5-4.
Logan Gilbert got through six innings by the skin of his teeth, with three solo shots coming in the last frame.
Gilbert’s efficiency issues over the past two seasons are well documented. After throwing a combined 3.8 pitches per plate appearance from 2022 through 2024, Gilbert threw 5.2 per plate appearance from May 2025 through the end of 2025. Batters’ adjusted to his style of pitching, laying off the splitter thanks to the predictability of its usage, but they still had issues squaring up the pitches, jacking up his pitch counts thanks to tons of foul balls and good takes.
Highs, Lows, and Other Notes from Mariners’ Three Losses to Royals
If there is to be a moment when the 2026 Seattle Mariners finally put early woes behind them, it will not be for quite some time. The team got swept for the third time in the season, this go around by a Kansas City Royals team that had been 12-19 with a -22 run differential. The first two games were thin margins, winnable for the Mariners, but they weren’t at all able to salvage the third game as hitting and defense broke down once more, a Groundhog Day-like occurrence even as April has turned to May and numbers are piling up in the wins and losses column.
As befits a set of bad losses, the M’s went right up to the edge of victory multiple times, but ultimately let it slip through their fingers. Let’s go over the highs and lows of the series, from mistakes that would be bad in grade school T-ball to a pitching performance worthy of Randy Johnson.
Very High: Emerson Hancock struck out 14 in a seven-inning masterpiece on the night the M’s retired the Big Unit’s number.
Things in this sport can change on a dime, but for now, Emerson Hancock has vanquished all doubts of him being an MLB-worthy starter. He precisely used his four-seamer, sweeper, cutter, and even sinker to fold one Royals hitter after another like his opponents were cheap lawn chairs. By the time he exited the stage at the end of the seventh, 103 pitches to his name and his team nursing a one-run lead, a near-sellout crowd in T-Mobile Park gave him the a roaring ovation.
Another “Rock” Detonation Raises Rotation Questions for Mariners
In Luis Castillo’s first start of the season, he blew down the New York Yankees with basically two pitches: his four-seamer and slider.
Over the following five outings, Castillo has given up less than four runs just once and has not finished a single sixth inning. Over that time, he has given up 35 hits, 24 runs, and 20 earned runs in 22 ⅓ innings, an 8.06 ERA over that time.
Five of those innings came on Monday night in rainy Minnesota. Although in his previous four starts (also struggles of outings, though not without bad defense behind him), he had struck out 16 and issued seven walks while giving up two homers - it was all hits in the field that had sunk him - Monday’s game was bad in the so-called three true outcomes and bad in the actual result. Castillo gave up two home runs, walked two batters, and struck out three. He gave up seven hits in total and just as many runs.
The Mariners’ loss on Monday started and ended, mostly, with Castillo’s bad start. Sure, debutant Alex Hoppe’s second inning of work fell off the rails as his control waned and hitters adjusted to his slider, but the M’s had essentially decided on pushing Hoppe as far as they could to mop up the game. Sure, the Mariners offense took quite a while to wake up, but they managed to put four runs on the board.
The question has to be raised: does Castillo’s slump warrant a change in outlook for the Mariners about how to utilize him for the rest of the season?
Mariners’ Plan Finally Functions, but Questions Linger from Walk-Off Win vs. A’s
For better or for worse, the Seattle Mariners haven’t wavered from their game plan after losing 15 of their first 25 games. All across the team, the players have bought into the plan that the organization built, trusting the process to get them out of their current rut.
“I really rely on the hitting coaches to help us out every day, and they do such an incredible job, but I think it’s just staying on the process and having fun while playing, knowing that failure is your friend, and learning to accept it,” first baseman Josh Naylor told Mariners TV’s Ryan Rowland-Smith after hitting a walk-off single to salvage a 5-4 win in the team’s three-game series against the Athletics.
In a team sport, this stubbornness can be beneficial.
The best laid schemes of mice and men, to translate Robert Burns [1], often go awry. “No plan survives first contact with the enemy” goes a similar phrase often misattributed to 19th century Prussian general Helmuth von Moltke the Elder.
But trying to tweak a plan that is veering a bit off course can just end up making things a whole lot worse. For a baseball team, there are always going to be good and bad spells. The most effective plans have an inherent flexibility [2] - and if Seattle’s plans go fully off the rails, it will be because they are inflexible - but in the absence of anything else, believing in the process can end up being the best a struggling team can have.
Still-Sleepy Mariners Suffer Sixth Loss in Eight Games, Lose Series to Athletics
SEATTLE, Wash. - The M’s didn’t look much worse on Tuesday night than they had all year. The problem was that they didn’t look any better, either.
All they have shown in the first 25 games of the season has been mediocrity, inconsistency, and a gradually weakening confidence in their own abilities. The team hasn’t fallen fully off the table, but as the drudgery continues seemingly indefinitely, the phrase “right now” will become an ever more faded addendum to the phrase “this team is bad.”
Because let’s be realistic: the M’s can’t bank on a 10-plus game win streak to propel them out of the herd every year at the last moment; at some point, they need to learn how to start the regular season strong and not let up. Lifeless 5-2 losses to a sneakily threatening divisional rival can only happen so often for a team with World Series aspirations.
Luis Castillo threw a decent outing, but a high pitch count and loss of secondary control late forced him out early.
For an organization used to unearned no-decisions, Luis Castillo’s five innings of two run ball was about the platonic ideal of a no-decision.
Mariners Should Learn Two Lessons from Monday Loss to Athletics - But Will They?
The old adage goes as follows: you win a third of your games, you lose a third of your games, and it’s the third in the middle that counts. So it goes for baseball teams and aspiring politicians alike.
Monday’s game was squarely one of those middle games, but the reasons the Mariners lost 6-4 can be sorted into two camps: roster construction and roster usage. The M’s went 1-12 with runners in scoring position, but this is something the team basically just has to weather for the rest of the year when it shows up.
But as for the use case of Casey Legumina and when to take out the left-handed member of a platoon? The M’s and manager Dan Wilson got a couple pieces of useful information on Monday night.
That information, however, only goes so far as the Mariners will take it. But first, a little on the initial five and a half frames.
Mariners Slug Enough Sunday Homers, Take Home Series against Rangers
When the M’s dropped Friday night’s game 5-0, their ninth straight loss against non-Astros teams, they found themselves on the edge of disaster. But two games later, they aren’t in that bad of a spot for the rest of the year, with the season series against the Rangers a manageable 2-4 despite the sweep in Arlington.
Sunday’s rubber match was decided by two things: home runs and Bryan Woo. Seattle scored all its runs via the longball in their 5-2 victory while Woo did Woo things on the rubber to keep the Rangers off the board for all but one inning of the game. It’s still a ways until a true turnaround can be declared, but the M’s did what they had to do in their weekend day games.
They also mash in the stellar Steelheads threads, for what it’s worth.
Bryan Woo dealt a cold dish to Rangers hitters, going seven innings and squeezing out most of the life from Seattle’s AL West foes.
One way to describe the skill of the Mariners pitching staff is as follows: on any given day, any of the Mariners starters can look like the ace. First among equals, however, is Bryan Woo. He had not looked any worse than his two stalwart previous years to start 2026, with a 2.16 ERA, 2.24 FIP, and 0.920 WHIP over his first four starts.
