Probable Pitchers
Athletics: RHP Joey Jump
Jump has been one of Oakland’s most consistent arms, featuring a mid‑90s fastball and a sharp slider. He has allowed three runs or fewer in five of his last seven starts and has shown improved command in June. His challenge will be navigating San Francisco’s left‑handed bats in a park that suppresses right‑handed power.
San Francisco: RHP Tyler Mahle
Mahle continues to work back into form after injury, leaning on a four‑seam/slider mix with above‑average strikeout potential. He has been more effective at home, where his ERA sits below 3.80. However, he has struggled at times with walks and deep counts.
