Mariners 8, Astros 3: Raley, Garver Homer as Seattle Wins Series

The lead

May 14, 2026 - Houston - The Seattle Mariners kept owning this matchup. Luke Raley hit a three-run homer in the first, Mitch Garver added his first long ball of the season, and Seattle beat the Houston Astros 8-3 at Daikin Park, per the Associated Press recap on CBS Sports.

The Mariners improved to 7-1 against Houston this season and took three of four in the series, according to AP.

How the game turned

Raley's 10th homer of the year and third of the road trip scored the game's first runs in the first. Garver, starting behind the plate for the injured Cal Raleigh, homered in the fourth to score J.P. Crawford and make it 5-1.

Cole Young doubled in a run in the sixth, and Crawford doubled in the eighth to plate Brice Matthews and cap Seattle's scoring. Yordan Alvarez homered for the 14th time this year in the third, and Braden Shewmake doubled in two runs in the sixth for Houston.

Alvarez and Shewmake went a combined 5-for-7; the rest of the Astros lineup was 0-for-25, per AP.

Pitching and matchup notes

Luis Castillo (1-4) earned his first win of the season with 5.2 innings, three runs, four hits, six strikeouts, and four walks. Domingo Gonzalez worked the final two frames. Mike Burrows (2-5) took the loss after seven runs on eight hits in 5.2 innings.

Bats that changed the board

Raley and Garver supplied the early leverage Seattle needed on the road. Crawford stayed in the middle of the action with multiple extra-base hits in a lineup that did not need Raleigh's bat to carry the night.

AthX Engine fantasy angle

Seattle's 15 AthX Engine team FP paired with Raley's 13 hitting FP and Castillo's 20 pitching FP on the daily board. Road power in the first inning still moves AthX Engine team totals before the bullpen finishes the job. AthX Engine scoring is separate from dynamic pricing.

What comes next

Houston hosts Texas on Friday. Seattle returns home for San Diego, per AP.
