Mariners Beat Astros 3-2 in AL West Series Finale as Raleigh, Arozarena Homer

On Sunday, August 16, 2026, the Seattle Mariners edged the Houston Astros 3-2 at Daikin Park in the rubber game of a pivotal American League West series. Randy Arozarena and Cal Raleigh homered for Seattle, Bryan Woo worked six strong innings, and Andrés Muñoz closed out his 22nd save in a nationally televised Sunday Night Baseball finale that tightened the division picture.

The Mariners took two of three in Houston after Friday’s 10-inning Astros walk-off and Saturday’s 10-5 Seattle blowout. Sunday’s low-scoring win pushed Seattle to a 9-2 edge in the season series and gave the club meaningful ground in a race Houston still leads — but one that no longer looks comfortable.

Houston entered the weekend with a slim division lead and a chance to put distance between itself and a Mariners club that had already owned the head-to-head matchup. Instead, Seattle left town having won the series and carrying momentum into a week that will test both rotations before a potential late-September rematch in the Pacific Northwest.

How the game unfolded

Arozarena set the tone in the first inning, driving a Hunter Brown offering to left-center for a 1-0 Seattle lead. Brown labored with his command from the start — he walked the first two batters he faced in the third — and the Mariners capitalized when Dominic Canzone lined a two-out RBI single to right-center. Seattle led 2-0.

Houston answered in the fourth. Jeremy Peña opened the bottom of the inning with a solo home run to right, cutting the deficit to 2-1 and giving the Daikin Park crowd its first burst of energy on a humid August night.

Brown escaped further damage in the fourth after walking three straight batters to load the bases with two outs, striking out Brendan Donovan to end the threat. He finished with five walks in five innings, allowing three hits and two earned runs while striking out five.

Woo, meanwhile, held the Astros to three hits and two runs over six frames with five strikeouts, continuing a pattern of effective starts against Houston. The right-hander improved to 9-8 on the season and has been especially sharp in this matchup historically.

Raleigh’s blast and Allen’s answer

The sixth inning delivered the game’s decisive swings — and a snapshot of two hitters moving in opposite directions.

Josh Naylor singled to open the top half but was caught stealing for the second out, briefly killing a rally. Raleigh then turned on a pitch and sent a solo shot to left, extending Seattle’s lead to 3-1. It was only the catcher’s 13th home run of 2026 after he led the majors with 60 a year ago, a power drop that has shadowed the Mariners’ offense all summer.

Nick Allen answered immediately for Houston, leading off the bottom of the sixth with his second homer of the season to make it 3-2. The Astros loaded the bases again in the seventh after a walk and two singles, but reliever Bryan Abreu retired Raleigh on a popout to end the threat.

Seattle threatened once more in the seventh, loading the bases with two outs before Abreu again got Raleigh to pop out — this time keeping the one-run margin intact heading into the late innings.

Late-inning drama

The eighth inning nearly flipped the game. With Houston down a run, Jose Altuve singled on a pop-up that Seattle reliever Seranthony Domínguez tripped and failed to catch, loading the bases with two outs. Manager Joe Espada had Yordan Alvarez available off the bench, and the crowd at Daikin Park rose expecting a tying knock.

Domínguez recovered. He struck out Daulton Varsho on three pitches to escape the jam, preserving Woo’s lead and setting up Muñoz for the ninth.

Muñoz walked one batter but otherwise navigated a scoreless final frame for save No. 22, sending the Mariners to their second win in three nights in Houston and capping a series that felt far larger than a mid-August date on the calendar.

Standout performances

Player	Line / moment
Randy Arozarena	Solo HR in 1st; early offense
Cal Raleigh	Solo HR in 6th; 13th of season
Bryan Woo	6.0 IP, 2 ER, 3 H, 5 K — W (9-8)
Andrés Muñoz	Scoreless 9th — SV (22)
Dominic Canzone	RBI single in 3rd
Jeremy Peña	Solo HR in 4th
Nick Allen	Solo HR in 6th
Hunter Brown	5.0 IP, 2 ER, 5 BB — L (3-3)

Woo’s outing stood out on a night when both bullpens had been taxed through the weekend. Houston had leaned on returning arms including Ronel Blanco and Hayden Wesneski during Saturday’s loss, and Sunday’s tight scoreline meant every pitch from the middle innings onward carried division weight.

Brown’s control issues — five walks in five innings — echoed concerns raised in Houston media after the Astros’ pitching staff absorbed another difficult weekend against a team that has had their number all year.

AL West standings and what’s next

The loss did not cost Houston the division lead, but it narrowed the margins in a crowded West.

Team	Standing snapshot (postgame)
Houston Astros	First place — two games ahead of Texas
Seattle Mariners	Four games back — hold the season tiebreaker over Houston
Season series	Mariners lead 9-2

The clubs are scheduled to meet once more — for a two-game series in Seattle during the final week of the regular season — a slate that could decide the division if the race stays this tight.

Both teams are off Monday, August 17. On Tuesday, Seattle opens a road series at Milwaukee, while Houston hosts the Los Angeles Angels at Daikin Park.

Discussion

A 3-2 Sunday night game rarely tells the whole story of a division race — but in Houston, it underscored how thoroughly Seattle has handled the Astros in 2026.

1. The Mariners are 9-2 against Houston this season. Can the Astros flip that script in a potential late-September two-game set in Seattle, or has Seattle already seized the psychological and tiebreaker edge?

2. Cal Raleigh has 13 home runs after leading MLB with 60 in 2025. If his power does not return down the stretch, can Seattle still make a serious AL West or wild-card push — or does this win paper over a larger offensive problem?

Where do you see the AL West landing — and does Houston’s pitching depth hold up through six more weeks?
