Michael Saunders hit a two-run infield single in the seventh inning to lift the Seattle Mariners to a 3-1 win over the Houston Astros on Thursday night.

With the game tied at 1, the bases loaded, two outs and a full count, 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.  Replays showed Saunders beat the pitcher to the bag by a half foot.

Jose Altuve homered on the game's first pitch for the Astros, who have lost three in a row.

Dominic Leone (1-0) pitched 1 2-3 innings for his first major league win in 16 appearances, and Fernando Rodney pitched a perfect ninth for his 12th save.

Houston starter Jarred Cosart (3-4) had kept Seattle's offense largely bottled up until the seventh inning.
