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.
Bullpen Locks Down Four Frames, Mariners Eke Out 3-1 Win in Houston
It was power on power in the bottom of the ninth. Mariners closer Andrés Muñoz, who had reached 101.3 miles an hour two pitches earlier, had a 2-2 count against Yordan Alvarez himself. Alvarez represented the tying run, and with 13 home runs already this season, he was a real threat to knot the game.
Muñoz tossed his rarest pitch, a 93.2 mile an hour changeup that tailed away from Alvarez. Expecting either a roaring fastball up or a slider along the lower edges, he was completely flummoxed; the Mariners won 3-1 as Alvarez struck out.
For a team desperately in need of a hot streak, getting any win on the board against Houston was a plus. George Kirby didn’t go as deep into the game as the M’s would have hoped and the bats fell silent for nearly the entire game, but they got just enough production while Kirby and every other arm stepped up enough run-prevention wise to notch Seattle’s 20th victory.
Mariners hitters put three early runs on the board but fell familiarly silent as the game wore on.
The second inning was fruitful for Seattle. Randy Arozarena knocked a one-out single into right and Luke Raley walked to set a two-runner table, and with two outs, both Dominic Canzone and Cole Young found the outfield for an RBI each. Julio Rodríguez rocked a towering homer to begin the third.
And then 20 of the next 23 batters made outs.
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.
Banged Up Mariners’ Bullpen Needs to Weather Mid-May Storm
During a 162-game marathon of an MLB season, there is bound to be some attrition and injuries. It’s a natural part of the game. Every team goes through it. It’s not very often that a specific position group on one team gets hit seemingly all at once with the injury bug.
The Seattle Mariners are currently down three different relievers that they were counting on to get big outs late in games. Flamethrower Matt Brash and lefty Gabe Speier seemingly got hurt on the same day. That means they quite literally are without the two top bullpen arms manager Dan Wilson uses to get through the seventh and eighth innings before the closer Andres Muñoz closes it down in the ninth.
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.
Mariners Bats Give Kirby Vintage King Félix Treatment, M’s Drop Winnable Contest to Braves
The names and faces change but the general concept remains the same. Gone are the days when a pitcher like Steve Carlton could win 27 games for a team that only won 59 games total; in modern baseball, such pitchers get saddled with no-decisions, a concept pioneered by a 13-12 Félix Hernández in 2010 who won the Cy Young Award on the back of his league-leading 2.27 ERA.
That was still 21.3% of that awful Mariners team’s wins. They weren’t quite as bad as Carlton’s old side. They may have given 702 plate appearances to Chone Figgins and 278 more to Milton Bradley, but there are few teams who were ever as bad as the ‘72 Not-Really-Phightin’ Phils.
Arisen during the career of that selfsame Hernández was the term “Félix Quality Start”, based on the definition of quality start (six innings or more, three earned runs or less) but narrowed in scope to seven innings or more and two earned runs or less. Hernández got plenty of those in his career.
Another Mariner got such a start on Tuesday night, and like a lot of those “King Félix” outings of old, his team lost 3-2. Whether it is an aberration or a harbinger, it is still too soon to tell. But the hour of judgment is drawing nearer than those in T-Mobile Park might like to admit.
George Kirby put together a “Félix Quality Start” against one of the best teams in baseball.
With a direly stretched bullpen, the Mariners needed their starter to go deep into the game. And with an offense once again struggling to put anything together, he needed to keep the Braves to a low score.
Bumpy Stretch For Rotation Blocking Mariners’ Breakthrough
One of the clear strengths of the Seattle Mariners at the beginning of the 2026 season was their starting rotation. Last season, they ranked fourth in Major League Baseball in innings pitched as a starting rotation and 11th in FIP (which is ERA but factoring out fielding luck).
Bryan Woo and Luis Castillo eclipsed 180 innings pitched. Two of their starters had an ERA better than 3.50. Three of them exceeded 160 strikeouts. Four of their starters made at least 23 starts last season. Eight different players needed to make at least two starts. For context, the World Series champion Dodgers had 14 different players make multiple starts. The American League champion Blue Jays needed 11 such starters.
They had one of the strongest, most reliable rotations in baseball last year. With the same cast of characters coming into 2026, the consensus was the Mariners would be able to lean on their starting pitchers to another postseason run. However, over the last few weeks, the starting pitching has not been the strength, but the weakness of this Mariners club.
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.
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.
Randy Johnson’s Legacy with Mariners is Indelible
The Mariners are set to retire Randy Johnson’s No. 51 this weekend during their series against the Kansas City Royals. The festivities kick off with “Randy Johnson ‘80s Jersey Night” on Friday. The ceremony will be held before Saturday’s game.
It’s not very often that a franchise has two of its icons wear the same number. Ichiro Suzuki also wore No. 51 for Seattle, which was retired on August 9, 2025, after he was inducted into the Baseball Hall of Fame.
“The Big Unit,” Randy Johnson, was inducted into the Baseball Hall of Fame in 2015. Now, 11 years later, he gets the ultimate honor from the Seattle Mariners of having his number retired. He was also inducted into the Mariners’ franchise Hall of Fame in 2012.
It’s Time to Take Mariners’ Cole Young Seriously Among MLB’s Best Young Second Basemen
There were a lot of different paths the Seattle Mariners could have taken this offseason when it came to second base.
Jorge Polanco hit .329 with a 1.015 in the final five weeks of the season last year, splitting time between second base and designated hitter, but that path closed when the New York Mets signed him to a two-year, $40 million contract this winter, ending his tenure in Seattle. Luis Arraez was also a popular free agent who could play second base, while buzz surrounded a potential blockbuster trade for Ketel Marte. The Mariners decided to not pursue external candidates for second base. When they traded for Brandon Donovan, it was for him to play third.
This partially paved the way for the Mariners to give Cole Young a long runway as one of the franchise’s staple infielders.
Apparently, all Young needed was more time to settle into his Mariners uniform. Because now, he looks like one of the best young middle infielders in Major League Baseball.
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.
Rodríguez, Naylor, Young Hack Timely Hits as Mariners Mash Minnesota Late
Here’s a stat: Julio Rodríguez has more triple doubles in the city of Minneapolis than Nikola Jokić does in the calendar year 2026.
Well, adding a three-double baseball game into the widely accepted hoops definition of “triple double” allows that to be true. It’s also a testament to the defensive skill of one Rudy Gobert, who has finally and resoundingly managed to convince the world that he is actually good at basketball.
As far as Rodríguez is concerned, his three doubles - the baseball version - set a couple of tables for Seattle and cleared their last, and the center fielder accounted for two runs scored and two others knocked in during the Mariners’ 7-1 victory over the Minnesota Twins.
It wasn’t just Rodríguez, as Josh Naylor and Cole Young offered some timely hits of their own while starter Logan Gilbert wriggled himself out of enough pickles and jams to make some truly unique culinary concoctions, even while only going five innings. The M’s, after all their tribulations to start the season, are a game behind .500.
Logan Gilbert showed a bit of adjustment but still had to Houdini his way out of a five-inning start.
It is often said that pitchers are crazy. Usually, this refers to intensity or the way the staff interacts with the rest of the players, and it is most stereotypically associated with the isolated (and thus mysterious) bullpen.
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?
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.
Living on the Sweet Spot, Two Mariners Dialed in to Open 2026 Season
You hear it the second you start playing baseball as a kid. “Find the sweet spot” on the bat. If you rope one to center field, you might hear a parent or coach yell “way to find the sweet spot!” They call it the sweet spot of the bat for a few reasons. In my personal experience, that was the spot on the bat where it didn’t even feel like you made contact. The contact between ball and bat was so optimal, that it didn’t reverberate into my hands at all.
Of course, for big leaguers, the sweet spot really means, the highest quality of contact. In fact, MLB’s glossary has an official definition for “the sweet spot.” It states, “colloquially, a player who hits the ball solidly is said to have gotten the "sweet spot" of the bat on the ball. The sweet spot classification quantifies that as a batted-ball event with a launch angle ranging from 8 to 32 degrees.”
So, it’s not necessarily a geographic location on the bat itself. Rather, it’s the quality of the contact, mostly considering the launch angle.
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.
