# Mariners 3, Astros 1: Pitching Depth Carves Up Houston in AL West Tilt

> Seattle's bullpen and clutch hits deliver a 3-1 win over Houston, tightening the division race.

The Seattle Mariners beat the Houston Astros 3-1 on Tuesday night, leaning on a deep pitching staff and timely hitting to secure a critical AL West victory.

Starter Bryce Miller worked five efficient innings, allowing one run on four hits while striking out six.

The bullpen took over from there: Trent Thornton, Justin Topa, and Andrés Muñoz combined for four scoreless innings, with Muñoz earning his 15th save.

The Mariners broke a 1-1 tie in the sixth inning when Julio Rodríguez laced an RBI double off Astros reliever Bryan Abreu.

Cal Raleigh added an insurance run with a sacrifice fly in the eighth.

Houston's lone run came on a solo homer by Kyle Tucker in the fourth, but Seattle's arms silenced the rest of the lineup, which went 1-for-9 with runners in scoring position.

This win tightens the AL West race, pulling Seattle within two games of first-place Houston.

The Mariners have now won four of their last five against the Astros this season, proving their formula of elite pitching and opportunistic offense can hang with the division's perennial powerhouse.

What's next: The Mariners send Luis Castillo to the mound Wednesday for the series finale, looking to sweep Houston and seize sole possession of first place.
