Mariners edge Astros to take AL West series and close division gap to four games

A tight series finale decided by Mariners relief pitching

Seattle closed a three-game series at Houston with a 3-2 victory, leaning on its bullpen to navigate two late bases-loaded jams and secure its first road series win since early May. The game unfolded as a Sunday night matchup with both clubs still in the American League West race, and the Mariners improved to 59-66 while the Astros fell to 63-62, narrowing their division gap to four games.

Key swings on offense

Randy Arozarena opened the scoring with a solo homer, his 17th of the year, and Dominic Canzone added an RBI single later in the third to push Seattle ahead 2-0. Cal Raleigh extended the lead with a sixth-inning solo shot, his 13th, before Houston answered. Jeremy Peña hit a fourth-inning solo homer, his 14th, and Nick Allen added a sixth-inning solo blast, his second, to pull the Astros within a run at 3-2.

Two late jams and a save milestone

The game's tense finish hinged on consecutive bases-loaded threats. Houston loaded the bases with one out in the eighth inning, prompting Seattle manager Dan Wilson to call on Seranthony Domínguez, who struck out Daulton Varsho on a splitter to escape the inning. The Astros again loaded the bases in the seventh before Bryan Abreu recorded a key out. Andrés Muñoz then closed the ninth by striking out Taylor Trammell for his 100th career save, preserving the one-run margin.

Astros' missed chances at the plate

Houston's late-inning urgency produced traffic on the bases but not the decisive hit. Yordan Alvarez's two-out single in the eighth put the potential tying run on first, and manager Joe Espada pinch-ran Cam Smith, removing the major-league OPS leader rather than carrying him through the late innings. After Isaac Paredes singled and Altuve followed with a pop-up infield single that fell when Domínguez tripped, the Astros still could not push across the tying run, with Varsho's foul ball and strikeout ending the rally.

What remains on the Mariners' plate

Beyond the standings shift, the series win marks Seattle's first road series victory since May 2, a streak that has now ended in a division setting against the team it trails. The loss leaves the Astros with a four-game cushion in the AL West with six weeks left in the season and questions about whether late-inning offensive execution can match the tight margins the division race is producing.
