The Oakland Athletics and Detroit Tigers are set to determine the winner of their three-game series on Sunday. In a dramatic 13-inning game on Friday, Seth Brown's walk-off RBI single secured a 7-6 victory for the Athletics, dealing a blow to the Tigers' playoff hopes. The Athletics have shown resilience with multiple walk-off wins recently, as they prepare for a future move to Las Vegas. The Tigers, currently 5.5 games behind in the wild-card race, will need a strong finish to stay in contention.
