In the third inning, a single by Canzone allowed Rodden to score, extending their lead to 2-0. The Astros responded in the fourth inning when Jeremy Peña hit a home run to right, narrowing the gap to 2-1. However, the Mariners struck again in the sixth inning with a homer from Cal Raleigh, making it 3-1. The Astros managed to pull one back with another home run, this time from Allen, but it was not enough to overcome the Mariners.
