Astros blank Mariners 7-0 behind Walker, Paredes, Alvarez homers

A Three-Homer Showcase

The Houston Astros dismantled the Seattle Mariners 7-0 at T-Mobile Park on Wednesday, September 23, 2026. The decisive factor was a trio of solo and multi-run home runs that stretched the lead into insurmountable territory. Yordan Alvarez provided the finishing blow in the eighth inning, launching a 386-foot shot to right field.

That blast drove in Jose Peña and marked the final run of the afternoon. Earlier, Carlos Correa and Jose Altuve contributed to the offensive surge, but the power hitting from Alvarez, Walker, and Paredes defined the game's flow.

Early Momentum and Relief

Houston struck first in the top of the first inning. Alvarez singled to right field, allowing Peña to score and establish a 1-0 lead. The margin widened significantly in the third inning when Walker connected with a 377-foot home run to left field.

That blast cleared the bases, sending Altuve and Diaz home to extend the Astros' advantage to 4-0. By the sixth inning, Paredes added to the total with a 372-foot homer to left field, pushing the score to 5-0. The Astros maintained their offensive pressure without allowing Seattle to score a single run.

Pitching Performance

The Astros' pitching rotation and bullpen combined for a perfect shutout. Cristian Javier started the game, pitching two innings while allowing one hit and walking two batters. He was followed by a deep bench of relievers who kept the Mariners' offense in check.

Miguel Ullola recorded the win, pitching two scoreless innings with two strikeouts. Bennett Sousa also pitched two innings, striking out three batters. AJ Blubaugh and Logan VanWey finished the game, each pitching two scoreless innings.

VanWey struck out two batters in his appearance. The staff collectively limited Seattle to just five hits.

Mariners Struggles

Seattle's starting pitcher, Logan Gilbert, faced a difficult outing. He pitched four innings, allowing ten hits and four earned runs. He walked two batters and struck out three.

The Mariners' bullpen failed to stop the bleeding as they entered the game. Jose Ferrer pitched one and two-thirds innings, allowing one earned run. Eduard Bazardo, Carlos Vargas, and Michael Rucker also took the mound, but the damage was already done.

The Mariners finished with a record of 73-84, while the Astros improved to 78-79. Attendance at the venue was 33,382.
