First Pitch: 9:40 PM ET / 6:40 PM PT
Television: NBC Sports Bay Area / NBC Sports California
The Bay Bridge rivalry resumes Friday night as the San Francisco Giants (18–26) travel across the water to face the Athletics (22–21). The Giants enter in a slump, sitting eight games under .500 and struggling to find consistency on both sides of the ball. The A’s, meanwhile, have been one of MLB’s early surprises, hovering above .500 thanks to improved pitching and a scrappy, contact‑driven lineup. The pitching matchup features veteran right‑hander Tyler Mahle, still working back to full form after injury, against Aaron Civale, who has quietly stabilized Oakland’s rotation with his command‑first approach.
