San Diego Padres at Seattle Mariners

SEATTLE -- Gavin Sheets homered twice and drove in four runs, Lucas Giolito won his San Diego debut and the Padres beat the Seattle Mariners 8-3 on Sunday to sweep their six-game season series. Giolito, who signed a one-year contract with San Diego in April, was called up from Double-A San Antonio before the game to make his first start of the year. The veteran right-hander allowed only one hit, but was lifted after issuing three consecutive walks to begin Seattle's three-run sixth inning. Giolito (1-0) was otherwise strong, aside from hitting Mariners shortstop J.P. Crawford in the right triceps with a fastball in the third. Crawford exited in the fifth and was replaced by Leo Rivas.
