SEATTLE -- Mike Zunino hit his first grand slam and drove in a career-high seven runs to power the Seattle Mariners to a 9-2 victory over the Tampa Bay Rays on Saturday night.
Zunino, sent down to Triple-A Tacoma for two weeks in May after struggling offensively, had a two-run double in the second, an RBI single in the fourth, and capped a five-run fifth with his slam that put the Mariners up 9-1.
Rookie right-hander Sam Gaviglio (2-1) allowed one run -- a homer by Corey Dickerson to lead off the game -- and four hits in five innings.
