Mariners Win Series in Houston, Set Sail for Uncharted Waters with Raleigh Out
After their 8-3 victory against the Astros on Thursday, the Mariners are 7-1 with a +26 run differential against that team in 2026. They’re also 15-22 with a -7 run differential against every other team.
Thursday was something of a fulcrum for Seattle. It was the day the M’s officially sent Cal Raleigh to the 10-day IL, though this was an obvious development after his exit from Wednesday’s game with clear discomfort on the same oblique he had tweaked earlier. Mitch Garver caught Luis Castillo in the latter’s final full start for some time as the piggyback plan goes into effect the next time through the rotation. The cloud of these changes hung over the game’s activities, which saw the M’s take the bad Astros pitchers to task once more.
Brendan Donovan and Mitch Garver stood out on both sides of the ball on the day Cal Raleigh went to the IL.
There were two individual performances in particular that echoed Raleigh’s absence in a way. Garver, obviously, moved into the primary catching role upon his addition to the IL, while for Brendan Donovan, his performance was a lesson in the virtues of caution around early injuries.
Arozarena, Canzone Crush Stros Pitching, Raleigh Breaks Slump in 10-2 Mariner Win
Monday night and Tuesday night represented two very different kinds of Mariners victories. In the bottom of the ninth on the first night, the M’s got a win by the skin of their teeth, with Andrés Muñoz getting the better of Yordan Alvarez to finish out a badly-needed win for the M’s.
When Domingo González wrapped up the bottom of the ninth on Tuesday, things were far less tense. Although the Astros had runners on first and third, the M’s were already up 10-2, and with the final out, that was the final score. It was sublimely special for González, who had just completed his very first inning, but the Mariners’ offensive explosion had long since shattered all but the slightest chance of even the mighty Astros offense clawing back into the match.
Against the whole gamut of Houston hurlers they faced on Tuesday, the Mariners put up numbers. They scored 10 runs on 11 hits, six walks, and two batters hit by a pitch; they got hard hits on 57.6% of their batted balls. With runners in scoring position, the M’s went 2-for-8, but one of those hits was Dominic Canzone’s first career grand slam, which he slammed on the first pitch Astros starter Tatsuya Imai sent his way in the fourth inning.
Seattle took Tatsuya Imai to Randyland and the Can-zone.
The Astros’ big pitching signing of the offseason, Tatsuya Imai, hasn’t turned out how Houston had hoped in the first month and a half of the season. The last time he faced Seattle, he had to be pulled with one out in the first inning due to four walks and one hit batsman, then he wound up on the IL with right arm fatigue. He did better on his return start on Tuesday on account of the fact he went four innings. That’s about the only positive Joe Espada’s club got out of the outing.
Analysis: A Deep Dive Into Mariners’ Slugger Cal Raleigh’s 2026 Struggles
It certainly has not been the smoothest of starts for the Seattle Mariners, or their star catcher Cal Raleigh. Dating back to the World Baseball Classic in March, Raleigh has been under the spotlight for all the wrong reasons. From Handshake Gate with teammate Randy Arozarena, to his subpar hitting, Raleigh is under a microscope this season.
Fair or not, the expectations are sky high. How could they not? After all, he became just the sixth player ever to reach 60 home runs in a season. Once you enter the same company as Babe Ruth, Aaron Judge, Mark McGwire, Sammy Sosa and Roger Maris, the expectations change.
Still, Raleigh has stumbled out of the gate in 2026. Why? Could it be the weight of those crushing expectations? Locker room trouble with teammate Randy Arozarena? Or just simply, the ebbs and flows of the grueling marathon that is a 162-game regular season? Or is he injured and trying to play through it?
Jacks Full of Threes: Raley Clubs Seven RBIs, M’s Bash White Sox 12-8
Things go a lot more easily for a baseball team when they hit three home runs to score three or more men each. Good offense over nine innings can more than smooth out a bad inning on the other side, though the Mariners’ 12-8 win on Friday night against the White Sox took a while to get to the coasting stage.
In a sense, it wasn’t nearly as close as the score said; most of the high-end relievers were able to rest as Chicago scored three runs in the final two innings to turn a giant lead into a respectable one.
But in another sense (it was a one-run game until the seventh), the game was closer than its final score. M’s starter Emerson Hancock slipped quite a bit in the third inning and gave up five runs on the night, but recovered enough to go six innings and preserve the bullpen. Seattle’s first chance with the bases loaded didn’t produce anything else, but they broke the gates later on.
The big hero of the night was the still-mashing Luke Raley, who upped his season line to .258/.314/.567 with eight homers and 23 RBIs.
Luke Raley began the barrage with the first grand slam of his career.
The Mariners gave White Sox starter Sean Burke a couple of easy innings on Friday, falling in seven pitches in the first and 11 in the fourth. But crucially, they also put tons of traffic on the bags in the second and third, and though the second was underwhelming, things came together in the following frame.
Big-Time Bryan Woo Bounce-Back Outing Gives Mariners Series Win vs. Atlanta
It might have seemed that the Atlanta Braves were the worst possible team for a struggling Bryan Woo to face. Woo, whose arsenal depends almost entirely on two zippy fastballs thrown over the plate, was set to face an aggressive squad that feasted on fastballs. That ability to jump on the heater has been the lynchpin of Atlanta’s stellar opening salvo of the 2026 campaign, and Woo had to stare them down as the M’s tried to be the very first team to hand the Braves a series defeat.
On the other side of the ball, the Mariners needed to produce more with the stick, having logged quite a few uncompetitive innings on offense in both previous games in the series, with a pair of well-timed homers providing just enough runs on Monday but not on Tuesday. The hitting took a bit of an improvement overall on Wednesday, and though the sequencing didn’t do them many favors, the runs they scraped across were enough for a 3-1 victory.
There were banner days for several involved. For Julio Rodríguez, who came about 20 feet from denting the newly-unveiled Randy Johnson plaque with a mammoth homer; for Cole Young, who put together a three-hit outing; and for Josh Naylor, who showed up with the glove, the bat, and the well-renowned mind to find stolen bases.
But it all started with the guy on the mound, who gave his team an excellent chance to win the game.
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.
Mariners Suffer Second Straight Bryan Woo Beating, Drop Randy Johnson Series Opener to Royals
The Mariners and Royals spent most of Friday evening locked in a back-and-forth batter’s duel, with the Royals eventually coming out in front. In all the action of the game - from the Royals knocking four first inning runs off Bryan Woo to Julio Rodríguez’ two homers to a late Kansas City rally off Jose A. Ferrer to Alex Hoppe blowing down the Royals’ best hitters in the ninth only for the Mariners to go down with a whimper in the bottom half by a 7-6 score - there were a lot of moments that made the difference.
But among those, there is one that is perhaps most instructive in two concepts: one, that baseball is a game of inches where defense matters (you already knew that), and two, that a run in the first is worth as much as a run in the ninth. This isn’t about ABS, but based on how ABS strategy is often discussed, a reminder is perhaps in order.
Bryan Woo’s two bad bookends fell in two separate but similar buckets.
Woo came into his start against the Cardinals as a potential clear Mariners ace. He left the sixth inning of his start against the Royals having given up 13 runs in his last nine innings and carrying a 4.61 ERA.
The story of how he got rocked for seven runs in three innings against the Redbirds has already been told, though that game was not defined by the bad start thanks to a big-time offensive showing. The M’s got four homers to power six runs at home, but it wasn’t enough this time.
Young Slugs RBI Double, Slaps Two-Run Single in Mariners’ Comeback Win over Twins
A .500 batting average and a .500 on-base percentage. 16 total bases in 22 at-bats. A 1.227 OPS. One home run, two doubles, and eight RBIs.
Those were Cole Young’s hitting stats over the Mariners’ 5-1 road trip to get back to .500 baseball by the end of April. Three of those RBIs came in the Mariners’ 5-3 win in their rubber match against the Minnesota Twins on Wednesday and two were as timely as could be with the M’s down one in the top of the ninth.
What goes up must go down, but the second baseman’s offensive breakout has been the Mariners’ best friend more than once in the young season on plenty of different-color diamonds.
George Kirby kept the Twins to two runs despite a big fourth inning opportunity.
Just like Logan Gilbert on Tuesday, George Kirby didn’t get the defense behind him that he wanted, with uneasy outfield play extending a fourth inning that saw the Twins put a pair of runs on the board and ballooned his pitch count enough to end up nixing the quality start and adding some workload for the Mariners bullpen.
M’s Beat Cards 11-9 in Bizarre Back-and-Forth Battle Despite Woo Blowup
Whatever happened between the Mariners and Cardinals on Saturday afternoon in Busch Stadium, it was one of the most beautiful examples of the chaos and unpredictability inherent in baseball. Perhaps it was fitting that all nine innings were played in the sun, what with the pastoral pastime unfolding in such a way as it did.
This was a game where Connor Joe knocked a game-tying single and Will Wilson drove in two of the Mariners’ runs, while Bryan Woo got smacked around for four homers and seven runs in just three innings pitched. Cole Young was a triple away from the cycle, while Mitch Garver had a multi-hit game even while getting a would-be homer robbed by the glove of Redbirds left fielder Nathan Church - who in turn mashed two big flies of his own but made the final two outs of the Mariners’ 11-9 victory.
And it was Leo Rivas, the same man who came into the game hitting .141, who delivered the go-ahead hit in the top of the ninth. Unlike many of the previous games, Rivas started on the bench on Saturday, logging two appearances. But in a game full of inflection points and twists, Rivas’ two appearances were some of the biggest moments of the game.
Julio Rodríguez set the tone with a second deck shot in the top of the first and Will Wilson launched his first career homer in the second.
Coming into Saturday, Julio Rodríguez had logged a hit in 16 of his past 48 at-bats, but 12 of those had been singles. Still, his process had been very sound after the slump of his first couple weeks, with Rodríguez driving stuff up the middle, drawing walks, and limiting strikeouts.
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.
Mariners Free-Fall Continues with 5-0 Home Loss to Rangers
The Mariners dropped their fourth game in a row on Friday night, 5-0 to the Rangers. It was their ninth defeat in a row to teams not named the Houston Astros.
It was Seattle’s fourth shutout loss of the season, with the Mariners becoming the first MLB team to log a fourth game without scoring a run of the 2026 season. Seattle only produced two real scoring chances all game on Friday, and with such paucity of opportunities, even going 1-4 with runners in scoring position (good by 2026 M’s standards), they couldn’t scratch across a run.
Despite early shakiness and persistently bad outfield defense, Logan Gilbert gutted out a solid start.
For much of the first three games the Mariners and Rangers played against each other back in Arlington, the visiting M’s were able to put up early runs against the high-powered Texas pitching staff, even if their bats fell as dead as a doornail for the rest of the game.
M’s Fall Back to Fallen Bats, Offense Goes Limp in 4-1 Loss to Padres
Seattle took full advantage of a get-right series in the standings, at least, but when it came to resetting the hitters, the lessons evidently didn’t stick. The lone run of the Mariners’ 4-1 loss to the Padres on Tuesday was a bases-loaded sacrifice fly, with no other sources of production. Bryan Woo got handed his second loss of the season thanks to the resurgent incapability of his hitters and a little bit of poor defense to boot.
It’s beginning to seem like this is what the 2026 Mariners offense really is.
The Mariners offense took a big step back against healthy MLB pitching, failing to capitalize on some early opportunities.
On Friday, the Mariners had begun a series of cold versus cold, taking on a skidding Astros club and spitting out their rivals with a four-game sweep. From near-disaster to near-.500 was one thing, but Tuesday’s game presented a contest of hot versus hot. The Padres entered the series coming off a four-game sweep of the Colorado Rockies and with a five game winning streak, though the Dodgers’ hot start meant that the Dads were further behind first in the NL West (two games) than the M’s were in the AL West (one and a half games).
But against Petco Park’s perennial playoff contenders rather than a banged-up (in the understatement of the century) Astros hurling staff, the M’s had to deal with good starters and elite relievers.
Stock Watch: Who’s Hot, Who’s Not After Mariners Sweep Astros
The Seattle Mariners seem to have finally righted the ship after a very rough start. Following a four-game sweep of the rival Houston Astros, they sit at 8-9, right back in the thick of things in the AL West.
For that turnaround to happen, several players had to step up at T-Mobile Park over this past weekend. Let’s highlight three players who are on a hot streak right now, and three who still are waiting for things to thaw in the early stages of the 2026 season.
Naylor Bombs, Kirby Strikes Finish Mariners’ Four-Game Sweep against Astros
How quickly things can turn around for a baseball club. Just four days prior, the Mariners took a badly-needed rest day as they came off a five-game skid to round out an opening baker’s dozen contests where each series had been worse than the last: a four-game split, a three-game series loss to a good team (the Yankees), a three-game series loss to a bad one (the Angels), and a three-game sweep at the hands of the Texas Rangers.
And then an odd thing happened: the M’s got handed a get-right series by the Houston Astros of all teams. The same Astros that had tyrannized the division for a decade, with a philosophy of a never-ending window and an organization that seemed to churn out All-Stars like butter. But early in April, Houston’s arms have been either banged-up, straight-up bad, or both.
With that and a bit of mental fortitude, a Mariners offense who had scored 40 runs in their first 13 games finished up a 29-run four-game set with a 6-2 victory over their rivals on Monday, completing as big a sweep as an April series can offer.
Josh Naylor finally broke through his early-season slump, mashing two homers and knocking in five.
For much of the beginning of the year, even during the sparse games when the offense put up strong numbers, the bulk of the production had been coming from the bottom of the lineup. Even in the turnaround game on Friday and the thunderous comeback on Saturday, it was Randy Arozarena and bottom of the order that got the party started.
Crawford Completes Comeback with Walk-Off Single, Mariners Best Astros 8-7
“J.P.! J.P.! J.P.!” rang out the chorus of 43,294 happy, exhausted spectators on Saturday night. Perhaps some of the Central Washington students among them (who had a special discount for the game and got some CWU-themed jerseys) were planning on continuing the night on Lower Queen Anne or Capitol Hill; the older and wiser CWU alums in the crowd were probably set to take their modes of transportation home so as to get some shuteye. All of them shared in the electricity of the evening’s end.
Mariners shortstop J.P. Crawford hadn’t been part of much of the first two weeks of the season for Seattle, nursing a shoulder injury sustained in Spring Training, and the first five games of his season saw him hit a paltry .118 over 26 plate appearances.
“I was going crazy not being able to play,” Crawford told Mariners TV’s Ryan Rowland-Smith after the game.
The Mariners shortstop had put together a 1-3 game with two walks during Seattle’s skid-breaking win on Friday, hitting leadoff with Brendan Donovan out of the lineup with an illness. But Saturday night saw him punch through a pair of massive bases-loaded singles to bookend the team’s biggest comeback of the young year.
Randy Arozarena’s Mammoth Fifth Inning Homer Reverses Hitting Woes, M’s Beat Stros 9-6
The look on Andrés Muñoz’ face told it all as Leo Rivas stepped on third to complete the final out: exhaustion and catharsis.
It was a feeling that reverberated around Mariners country as the team won its first game and nearly a week, put more than two runs on the board for the first time in a few days, and had a solid defensive showing after scores of innings full of botched glovework.
The Astros’ struggling pitching and the Mariners’ struggling offense both showed early on Friday.
Ichiro’s statue unveiling outside T-Mobile Park on Friday night encountered an unusual mishap: the bat cracked and bent at the handle as the tarp was taken off to unveil it.
It was the proverbial picture that said a thousand words about the Mariners offense. Over the first 13 games, the Mariners had failed to score before extras in four of them. The whole batting crew had looked about as lost as three Roman legions in the Teutoberg Forest.
Analysis: What Does Underlying Data Say about Mariners’ Hitting Abyss?
There have been a lot of bad results with the bat in the first 13 games the Mariners have played in 2026, and for every bad result, there are 1,000 ways to quantify and describe it: worst in the league in average (.184), on-base percentage (.280), and slugging percentage (.301). The league’s second-lowest hard-hit rate (34.2%) and highest whiff rate (32.9%). Bat speed declines for Cal Raleigh, Julio Rodríguez, Josh Naylor, and others.
But with 149 games left to go, how much of this is actually meaningful and predictive? How much of it is pure noise?
The top lines are too early to tell right now; any answers will come from underlying data.
There isn’t much that can be told from the first 13 games as to which disappointing slash stats are because a good player is in a slump and which are because the player is plain overmatched. Both Aaron Judge and Willi Castro entered Friday with a .222 batting average, but it’s safe to say that their career OPSes of 1.025 and .696, respectively, are good indicators of who is more likely to get hot.
