Mariners 10, Astros 2

The Seattle Mariners defeated the Houston Astros 10–2 on Tuesday night after capitalizing on multiple Astros mistakes during the middle innings. Starter Bryan Woo controlled the strike zone across six innings, highlighted by Dominic Canzone’s grand slam in the fourth inning.

The Mariners finished with 11 hits as the Astros managed five. The Astros continued struggling to generate offensive consistency during key moments throughout the game.

Astros-Mariners Game Summary

The Mariners opened the scoring during the second inning after Cal Raleigh drew a walk against Astros starter Tatsuya Imai. Randy Arozarena followed with a two-run home run into the Crawford Boxes, marking the first home run surrendered by Imai during his major league career.

The Astros answered during the bottom half of the second inning. Zach Dezenzo lined a double into the gap before Braden Shewmake delivered an RBI single into shallow center field to cut the deficit to 2-1.

The Astros tied the game during the third inning after Jose Altuve and Yordan Alvarez drew consecutive walks. Christian Walker later lined an RBI single down the left-field line to score Altuve and even the score at 2-2.

The Mariners regained control during the fourth inning. Imai plunked Arozarena and Luke Raley before issuing a walk to J.P. Crawford to load the bases. Dominic Canzone, up next, launched the first grand slam of his major league career into right field to give the Mariners the lead again, this time 6-2.

The Mariners continued adding pressure throughout the remainder of the night. Crawford added an RBI single during the fifth inning before Arozarena drove in another run with a double during the seventh.

The Mariners scored their final run during the ninth inning after Crawford drew a bases-loaded walk.

Woo finished with nine strikeouts while allowing two earned runs across six innings before the Mariners relief core completed the final three scoreless innings.

What Went Right for the Astros

Braden Shewmake Delivered on Both Sides

Shewmake provided one of the Astros’ strongest moments during the third inning after turning an unassisted double play on a hard hit ball from Julio Rodriguez. The shortstop also recorded an RBI single during the second inning to drive in the Astros’ first run.

Christian Walker Continued Driving in Runs

Walker tied the game during the third inning with an RBI single over Brendan Donovan’s head in left field. The first baseman consistently produced hard contact and prevented the game from slipping away early.

Jayden Murray Stabilized the Staff

After Imai exited during the fourth inning, Jayden Murray helped settle the game by limiting additional damage across three innings. Murray allowed one earned run as he forced multiple fly-ball outs against the middle of the Mariners lineup.

What Went Wrong for the Astros

Command Trouble

Imai kept the Mariners relatively contained through the opening three innings before command issues changed the game during the fourth. Two hit batters and a walk loaded the bases for Canzone’s grand slam, ending Imai’s night after 3 2/3 innings.

Bryan Woo

Woo controlled the Astros lineup from the opening inning as he mixed elevated fastballs with effective secondary pitches. The Astros struck out nine times against Woo, including multiple strikeouts from the middle of the lineup.

Mariners Capitalized on Traffic

The Mariners consistently converted scoring opportunities throughout the night. They generated timely extra-base hits and forced Astros pitchers into difficult counts after drawing walks and creating traffic.

Quick Hits

Arozarena reached base five times and finished 4-for-4 with a home run, double, three RBI, and two runs scored for the Mariners.

Canzone recorded the biggest swing of the night with the first grand slam of his major league career during the fourth inning.

Mariners starter Bryan Woo tied his season high with nine strikeouts while allowing four hits across six innings against the Astros.

Altuve reached base twice and, during the third inning, scored after extending an early rally with a walk.

The Mariners relief corps combined for three scoreless innings as Alex Hoppe did not allow a hit across the seventh and eighth innings.

Cal Raleigh snapped an 0-for-38 cold spell with a base hit during the seventh inning, ending a prolonged hitless skid and helping the Mariners generate a late-inning scoring opportunity.
