Michael Saunders beat out an infield single in the bottom of the seventh inning to help the Seattle Mariners past the Houston Astros 3-1. Saunders infield hit came with the bases-loaded and two runs scored breaking the tie. Saunders hit a chopper to first and narrowly outraced pitcher Tony Sipp, who was covering the bag. The batters were running on the pitch, allowing two runs to score. The play was upheld after a brief replay review.

Dominic Leone picked up his first major league win in relief of Roenis Elias. Leone pitched one and two-thirds innings of scoreless relief. Fernando Rodney pitched a one-two-three ninth for the save.

The win gave the Mariners an even five hundred record at 23-23.
