SEATTLE (AP) — Luis Valbuena hit a pair of solo home runs, including a go-ahead eighth-inning shot, to give the Houston Astros a 7-5 victory over the Seattle Mariners Monday night.

Valbuena, who started the scoring with a blast in the first inning, opened the eighth with a homer to right on 1-1 pitch from Danny Farquhar (0-1). It was his fifth this season.

It was the first home run allowed by a Mariners reliever this season. Jed Lowrie added an RBI single in the inning.

Colby Rasmus also had his second home run on a 2-0 pitch from starter Hisashi Iwakuma in the fifth.

Tony Sipp (1-0), who worked the seventh and eighth, picked up the victory.
