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.
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.
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.
Familiar Culprits Waste Kirby Complete Game as M’s Drop Fourth Straight
The Mariners fielded their first full top-depth lineup of the 2026 season on Tuesday, but it didn’t lead to much production on the offensive side of the ball. The defense - this time, even standout defender Cole Young, though through positioning and not bad glovework per se - continued giving away runs to the Mariners’ opponents on the way to a one-run loss thanks to said baffled bats.
Kirby worked very efficiently early in the game, but yet more hibernating hitters and letdowns on defense gave him his first career loss to Texas.
Brendan Donovan hit a home run on the very first pitch of the game. Cal Raleigh had an excellent two-out piece of hitting against a top-edge fastball, driving it into center for an RBI single. That was the only hit with runners in scoring position, bringing the team’s RISP slash line down to .216/.327/.371.
But with a guy on the mound with a career 1.04 ERA against the Texas Rangers, those two runs still gave them a shot.
Bats Go from Quiet to Silent, Mariners Drop Third Straight to Open Texas Series
Sometimes, when a good team is in a rut of bad performance, it only takes one good break to open the floodgates and turn things around.
But when the M’s put up eight against the Guardians, or walked off the Yankees, or stole a theretofore scoreless match in extras from the Angels - or when Cal Raleigh launched one halfway into the upper deck on Monday night in Arlington, Texas - it was less like the great floodgates opening and releasing an overpowering torrent and more like little droplets of water gathering on the collection surface of a solar desalination plant: the tiny pellet of hydration was followed by yet more aridity.
Cal Raleigh finally found his stroke in his first at-bat of the game, torching a middle-middle Jacob DeGrom fastball 418 feet to right field.
What’s that old saying about the darkest time of the night? Well, the sun only shone for one at-bat in the top of the first and then quickly went away again (what’s the inverse of an eclipse?), but at least Cal Raleigh got himself into the .500s in OPS (talk about scarce droplets of water!) by the end of the night.
Sluggish Mariners Start Hitting Late, Drop Series to Yankees
Things won’t usually go well when you are scoreless for 16 straight innings and score one run in the span of 23 innings. Seattle dealt with quite a lot of those stretches in 2025, and even with a bolstered offense for the new year, it looks like that issue won’t go away, even if it’s the heart of the lineup in the doghouse this time.
Seattle made it interesting in the late innings, but too many mistakes on all sides of the ball gave Cole Young, one of the M’s riding a hot streak, the unfortunate task of being the final out.
George Kirby deals through five but gets some dear punishment from Paul Goldschmidt after walking two in the sixth.
If “Furious George” had forgotten how much he hates walks before Wednesday’s action, his second start of the season surely reminded him. All three batters Kirby walked came around to score, starting in the first inning as Cody Bellinger walked and stole second before Ben Rice scorched a double down the right field line for New York’s first run.
Cal Raleigh Walks Off Yankees, Mariners Take One-Run Win Despite Missed Chances
The Mariners exited the weekend four-game set against the Guardians having scored nine more runs than their opponents but with just as many losses as wins. One-run games on Thursday and Saturday both went against the hosts, with the team seemingly figuring out how to deploy its roster in close matchups.
Seattle faced another one-run game against a 3-0 Yankees team on Monday night, and although the pitching was filthy, both the defense and offense seemed to have a bad case of the Mondays, letting several opportunities slip past at the dish and serving up a key non-out to New York in the seventh. But all’s well that ends well, and none other than Cal Raleigh knocked the winning run home in the bottom of the ninth to put all the night’s adversity behind them.
Luis Castillo notches his 1500th strikeout against Aaron Judge to cap off six shutout innings.
Mariners starter Luis Castillo isn’t the ace he once was. His once-elite grounder rate from his time with the Reds fell to around league average in his last few years with the Mariners, and his above average ratio of homers to fly balls in 2025 suggested he got on the good side of the Seattle marine layer. Still, his decline into his 30s has thus far been a graceful one, with a 3.54 ERA and 3.88 FIP last year.
Hancock Stuns in First 2026 Outing, Mariners Thump Guardians 8-0
It all seemed to come together on Sunday afternoon. Unlike the first or third game of the series, where the Mariners kept it close but fell in the end thanks to some bullpen mismanagement, defensive miscues, and lethargic hitting - and unlike the second game, where two timely homers brought them to victory - there wasn’t a single moment of the fourth game between Seattle and the Cleveland Guardians where it seemed the pressure was on for the home crew.
Hitters up and down the lineup did their duty, the defense looked good, and that whole tone was set when a once-touted prospect whose bad luck had eaten his star finally seemed to turn a corner.
Hancock impresses in first 2026 start, tossing six no-hit innings and setting a career high in strikeouts.
Mariners starter Emerson Hancock came into 2026 with one more chance to become a major league starter. The former first-round draft pick has pitched to a 4.81 ERA, 5.23 fielding independent pitching (FIP), 1.359 walks and hits per innings pitched (WHIP), and a 2.06 strikeout-to-walk ratio. He had particularly struggled with control even more than walks as such, with errant pitches forcing him to groove a strike or two and get punished in bad situations.
Mariners Turn Three Hits into Five Runs, Tie Opening Guardians Series
The Seattle Mariners still haven’t hit a single through the first two games of the season. That didn’t matter on Friday night.
Cleveland Guardians starter Gavin Williams may have spun good enough stuff to punch out seven Mariners, but he also walked six, and timely round-trippers from Cole Young and Luke Raley put the M’s far ahead of the visitors and brought the team to its first win of the year.
“Furious George” deals with early homer and puts together a quality start to begin his 2026.
Chase DeLauter’s prospect stock is about as high as can be right now. After mashing two home runs in his regular season debut on Opening Day, day two hurler George Kirby became the third Mariner to foolishly leave a pitch on the lower inside part of the plate, exactly where the 24-year-old rookie likes it.
Old Mariners Bugbears Continue Biting in Opening Day Loss to Guardians
The more things change, the more they stay the same. It’s hard to say there wasn’t an air of that feeling in T-Mobile Park after the Mariners dropped their Opening Day contest 6-4 thanks to some shoddy relief work, unimpressive defense, and one-trick offense.
Four solo home runs were all the production the M’s could muster, and in a lot of games against the Cleveland Guardians, that might be enough (they scored slightly less than four runs per game last year). But Logan Gilbert once again struggled to go deep, outfielders lacked urgency on fly balls with men on base, and Gabe Speier caught the bad end of some J-Ram magic with men on base.
But for all the lingering of long-lamented woes, the newest guy on the roster burst his way onto the scene in a big way.
Brendan Donovan made the best first impression possible as the M’s new leadoff man.
The Mariners franchise is entering its 50th season this year, having notched its first game in the books all the way back on April 6, 1977. In all that time, no leadoff Mariner had hit a home run in his first at-bat of Opening Day. Not Dave Collins all the way back in that first season nor Harold Reynolds in the late ‘80s nor Ichiro in his Hall-of-Fame Mariners career. Of the 49 season-inaugural batters, not one had left the yard in that first at-bat.
Mariners Release Opening Day Roster; Crawford, Miller Notably Absent with Injury
With opening day right around the corner for the Seattle Mariners - at 7:10 p.m. Pacific on Thursday against the Guardians - the team has released its first 26-man roster for the 2026 season. The top of the depth chart, of course, is very much all over the M’s roster, from returning superstars in Cal Raleigh and Julio Rodríguez to new additions like Brendan Donovan and Jose A. Ferrer.
But of course it is not all sunshine and roses for the defending AL West champions. Longtime shortstop J.P. Crawford is out for the beginning of the year with a shoulder injury while Bryce Miller is working through an injury of his own, leaving holes in the middle infield and the back of the rotation. Leo Rivas is going to get some playing time at short in the meantime (and perhaps Cole Young might swivel
Assessing Three March Mariner Concerns Ahead of 2026 Regular Season
If the Seattle Mariners started the 2026 regular season 6-16-1 (ignore the tie), things would probably be nearing panic mode in T-Mobile Park. But given that it’s Spring Training, the record isn’t all that concerning as Opening Day begins. But from injury concerns to slow starts for stars, there are some points of worry for the M’s as the season comes into view. Just how worrying are these signs, however? Is there any meaning to be derived from them?
Concern 1: Injury questions for players up and down the roster.
Concern level: 4/10
The most-discussed injury question for the upcoming season has been Bryce Miller, and it seems likely by this point that he won’t be ready to start the regular season. The Mariners have Emerson Hancock and Cooper Criswell both available to fill in the fifth starter role - and I personally expect they’ll start with Hancock, with Criswell in the tank if Hancock again struggles as a starter - but they at least have some good indications due to both players’ performance in Spring Training. That doesn’t necessarily mean much for the regular season, especially in the top-line stats such as ERA and FIP, but the M’s have to be impressed with Hancock’s feel for the ball.
Three X-Factors in Mariners’ Success For 2026
For the Seattle Mariners to return to the playoffs in 2026, it’s obvious which usual suspects have to have strong seasons. Cal Raleigh, while unfair to be expected to mash 60 homers again, needs to be among the league leaders in home runs with a slugging percentage at least near .500. Julio Rodriguez needs to be a 30-30 threat again (30 home runs/30 stolen bases). The top three of the rotation need to be reliable and healthy. Andres Muñoz needs to keep throwing gas and stay healthy as well. That’s all a given.
But to get further than the Divisional Round this time around, Seattle will need contributions from other sources to get over the top. Which X-Factors, if they perform perhaps better than expected, could drive the Mariners finally to their first World Series berth?

Decisions Behind Disaster: Managerial Tendencies Sunk Mariners in Game 7
Mariners manager Dan Wilson made a decision that will live in infamy during Game 7, and the mistake cost the M’s the season. That decision and others on Monday reflected long-visible managerial tendencies that Wilson will have to adjust come 2026.
