The Astros score was buried early and never recovered Tuesday night, as the Mariners rolled to a 10-2 win on May 12, 2026, behind Dominic Canzone’s first career grand slam and Randy Arozarena’s four-hit night. Seattle turned a tight game into a runaway in the fourth inning, then kept adding to it while Houston kept missing chances to stop the slide.
Canzone’s slam came on the first pitch he saw with the bases loaded and nobody out, a shot that gave Seattle a 6-2 lead and landed after J.P. Crawford drew a four-pitch walk to open the inning. The ball left the bat at 105.5 mph and sailed into a night that had already started to tilt. It was the first grand slam of Canzone’s career, and it came just after the Mariners had put traffic on the bases with no one retired.
Arozarena helped turn the game into a blowout from the middle of the order. He drove a two-run homer into the Crawford Boxes, went 4-for-4 and finished three hits shy of the cycle, reaching base once on a successful ABS challenge of a would-be strikeout before being hit by a pitch. By the end, Seattle had put up 10 runs and kept Houston chasing a scoreline that only grew more lopsided as the innings passed.
Bryan Woo set the tone from the mound. He worked six innings, allowed two runs, struck out nine hitters and threw a career-high 104 pitches, finishing with 14 whiffs while keeping the Astros from ever fully settling in. Woo said after the game that it “wasn’t six-shutty, but it’ll do,” a blunt assessment from a starter who gave Seattle exactly what it needed while the offense did the rest.
The rest of the Mariners’ pitching held the door. Alex Hoppe threw two scoreless innings in the seventh and eighth, giving Seattle a clean bridge to the finish, and Domingo González made his major league debut in the ninth. Cal Raleigh, meanwhile, snapped an 0-for-38 slump with a single to right-center in the seventh inning and finished 2-for-4 with three runs scored, a small but important sign that the lineup was not running on just one hot bat.
The game carried a wider edge because of how Houston got to this spot. Tatsuya Imai had been activated for the start after spending the previous month on the injured list with arm fatigue, and his night again exposed how quickly the Mariners could turn patience into pressure. He retired only one batter, walked four and was pulled after 37 pitches on April 10 at T-Mobile Park in his earlier meeting with Seattle, a reminder of how the matchup had already tilted once before. On Tuesday, the Mariners were also working around missing bullpen pieces of their own, including Gabe Speier, Matt Brash and José Ferrer, but none of that slowed the result.
That is the part Houston has to sit with now: Seattle scored 10 runs without needing a clean, mistake-free game to do it. The Mariners did enough early, hit hard when the opening appeared and got enough from Woo and the bullpen to make sure the Astros score never got close enough to change the shape of the night.
