In the bottom of the eighth, the Astros tried to start a rally when Alex Bregman hit a two-run home run to left field to bring the game to 7-5, but reliever Andrés Muñoz was able to contain the rally to just two runs, striking out two Houston batters to get out of the inning.
Rodríguez tried to help the Mariners tack on some insurance runs in the top of the ninth, hitting a sharp line drive to right field that looked like it was heading for the seats, but the ball was snagged by right fielder Kyle Tucker just in time for the second out.
The Mariners sent Paul Sewald to the mound in the bottom of the ninth to thwart an attempt of an Astros rally. With one out, Sewald hit the pinch-hitter David Hensley with a pitch, putting a runner on base for Jose Altuve, who stepped up to the plate one swing away from tying the game. Sewald struck out Altuve, but then Jeremy Peña hit a single to shallow center field.
In need of one out, Servais pulled Sewald, and replaced him with Ray. Alvarez stepped up to the plate with two runners aboard, and hit a commanding three-run home run to right field to give the Astros a walk-off win and a 1-0 lead in the series.
