Seth Brown led the Oakland Athletics to a 3-2 walk-off victory against the Seattle Mariners, marking the A's second consecutive walk-off win. Brown's performance included a home run in the fourth inning and a game-ending single in the ninth, contributing to a season where he has faced challenges with consistency, batting just .242. Meanwhile, Cal Raleigh showcased his power for the Mariners with a two-run double but could not prevent the team's fourth consecutive loss. Seattle remains 5.5 games behind for the last American League wild-card spot, while Oakland has now secured six walk-off wins this season. Both teams are struggling, with Seattle losing four straight one-run games, and Mariners' pitcher Luis Castillo expressing hope for a playoff chance. The Athletics’ G.T. Ginn had a solid outing, allowing two runs over six innings, while Hogan Harris provided three hitless innings of relief.
