Background & Official Comments
The Padres signed Lucas Giolito to a contract in April to stabilize a rotation. Manager Craig Stammen adjusted the lineup, moving Fernando Tatis Jr. to leadoff, dropping Manny Machado to fourth, and placing Gavin Sheets in the third spot for consistency. Stammen said he trusted Sheets’ production and expected Giolito to live up to his “big-game” reputation.
Offensive Highlights: Gavin Sheets Leads Attack
Gavin Sheets delivered two home runs and an RBI double. He opened the game with a pitch from Mariners starter George Kirby for a 400-foot shot that gave San Diego a 1–0 lead. In the sixth, Sheets turned a changeup from Kirby into a 404-foot homer, extending the lead to 4–0. He finished 3-for-3 with walks, four RBI and scored twice. Sheets has faced Seattle, posting 15 hits, five homers and five doubles. Ty France added three hits and three RBI; Machado, Merrill and Tatis Jr. also scored.

Right-hander Lucas Giolito made his Padres debut after a call-up from Double-A San Antonio. He pitched five innings, allowing one hit, three runs, walks and three strikeouts. After issuing walks to start Seattle’s sixth inning, manager Craig Stammen replaced him with left-hander Yuki Matsui.
