The Mariners walked into Thursday with a soft landing in front of them and came out with another mess on their hands.
What looked like a favorable opener against the A’s turned into a 7-4 loss, with the Mariners striking out 18 times, watching another starter fail to give them enough length, and seeing Dan Wilson get ejected before the night was over. Julio Rodríguez did his part with three stolen bases, becoming the first player ever to begin a career with five consecutive 20-20 seasons, but the milestone disappeared into the loss column.
Seattle struck first and struck fast. Randy Arozerana led off the game with a walk, Julio doubled him in, Cal Raleigh singled home another run, Cole Young followed with a hit of his own, and Lazaro Montes added one more single to make it 3-0.
J.P. Crawford then walked to load the bases, but Brock Rodden struck out on a dropped third strike play to end the threat before it became a knockout punch.
That missed chance was a preview of the night. The Mariners kept putting runners on base, drawing walks in the second and third innings, but they couldn’t cash in. They eventually ran Jack Perkins after three innings, but he escaped with most of the damage limited to the first.
The problem was that Seattle’s pitching never let the game settle down.
Anderson, making the third start of his career, worked 4 2/3 innings and needed 79 pitches to get through the fifth. He opened by allowing a solo homer to Zack Gelof on a middle-middle fastball, then worked through traffic in the second and third with a pair of double plays helping him survive. He looked settled for a stretch, then the third trip through the A’s order got him.
Henry Bolte walked on four pitches, Gelof ripped a single, stole second, and Lawrence Butler followed with another hard hit that drove in two runs and put Oakland ahead 4-3. Anderson’s line ended at five innings, four runs, seven hits, two walks, and three strikeouts.
“Tonight doesn’t hold up to the standard I put on myself and my teammates put on me. Just a little unacceptable tonight,” Anderson said postgame.
“The [in]ability to put dudes away when I should have and walks is not really part of what I am as a pitcher. So I’ve got to clean that up.”
The Mariners briefly answered in the sixth. Arozarena doubled down the left field line, Canzone singled, and Julio cut the deficit to 5-4 on a ball that should have been a hit, though Alika Williams made a strong play to keep it on the infield.
But the bullpen couldn’t hold the line. Carlos Vargas gave up a solo homer to Donovan Walton to start the sixth, then hit Brian Serven, which brought warnings for both benches and set off Wilson’s ejection.
Vargas surrendered another single but got out of the inning. Gabe Speier then punched out the side in the seventh, but Eduard Bazardo allowed a run in the eighth on a walk and three singles, and Hoby Milner gave up another in the ninth on a pair of doubles.
The A’s finished with seven runs on 14 hits and three walks. Seattle’s staff has been the worst in the majors for two months, and Anderson’s debut into that group didn’t change the picture.
The offense kept giving itself chances, though it rarely finished the job. The Mariners piled up nine hits and eight walks, but the strikeouts kept swallowing rallies whole.
They had another two-walk inning in the second and again in the third, only to come away empty. They chased Perkins after three innings, but he still escaped with seven of his nine outs coming by strikeout.
Seattle’s last real push came in the seventh, when a two-out rally died with Arozarena striking out and throwing his bat down the third base line. They got a one-out chance in the eighth and came up empty again, with Josh Naylor and Cole Young unable to deliver. The ninth was quiet, and the game ended 7-4.
It came against the majors’ worst team, in the first game of the stretch where the Mariners face the easiest strength of schedule in baseball. After starting September 2-0 in Boston, the setup looked almost ideal for a late charge. Instead, Thursday became another reminder that nothing has come easy for this 2026 Mariners season.

Julio Rodriguez Is Giving Mariners A Long Term Problem They Can't Ignore
Julio Rodriguez is still contributing enough at the plate to keep the Mariners invested, but the shape of his season has become harder to ignore. His offensive profile has trended backward since his rookie year, and in 2026 he has settled at a .245 average with a .306 on-base percentage while still managing a respectable .708 OPS and 104 OPS+.
The bigger concern for Seattle is that the decline is not limited to one side of the ball. Rodriguez went from plus-9 runs saved last season to minus-4 this year, and when a player with his pedigree starts sliding both offensively and defensively, it puts the organization in an uncomfortable spot. The Mariners do not need a referendum on his talent, but they do need a clearer answer on where this is headed. [Read more 🡒]
Mariners Suddenly Have A Lazaro Montes Concern They Cant Ignore
Lazaro Montes gave the Mariners a brief scare after running into the right field wall and feeling soreness in his left hip, a jarring moment for a club that has leaned on his arrival as one more sign of the systems depth. He initially stayed in the game, but the discomfort lingered enough that he was eventually pulled for evaluation, turning a routine outfield play into a concern the Mariners had to sort out immediately.
The encouraging part is that X-rays came back negative, which at least removes one obvious worry from the equation. Even so, Seattle will keep a close watch on Montes and decide whether anything else needs to be done, a reminder that the margins for a young player can get thin fast when a hard collision sends him from the field to the training room.

Kade Anderson Is Forcing Mariners Fans To Reconsider One Rotation Hope
Kade Andersons first stretch in the majors has been bumpy, and it has given Mariners fans a reason to slow down on the early excitement around one of the organizations rotation hopes. The rookie has allowed several earned runs in his first few starts, but the underlying ingredients still look encouraging enough to keep the long view intact. His pitch mix has already shown it can work, which is usually the first sign a young starter has something worth developing.
What Anderson is learning now is less about raw stuff than about how to survive lineups that punish mistakes fast. The next step is sharpening pitch location and sequencing, the kind of refinement that often separates a promising arm from a reliable big-league starter. There is still room for optimism, too, since experience tends to settle this sort of adjustment, and a little more velocity could help the whole package play up if the command follows. [Read more 🡒]
