The Athletics erased an early deficit and beat the Seattle Mariners 7-4 at T-Mobile Park, turning a three-run first inning by Seattle into a controlled road victory. Oakland scored in five different innings and took command with a two-run fifth before adding insurance in the eighth and ninth. Seattle’s offense produced only one run after the opening frame, while the Athletics’ bullpen combined strikeout power with enough late execution to protect the lead.

The difference came on the mound after Seattle’s fast start. Jack Perkins struck out seven across three innings, overpowering hitters with swing-and-miss stuff, although his five walks gave Seattle repeated opportunities to extend innings. Scott Blewett added four strikeouts in two scoreless innings, and Luis Medina struck out three in 1.1 innings. Kade Anderson worked five innings for Seattle and kept the Mariners within reach, but four earned runs allowed left the home club chasing Oakland’s offense for most of the afternoon. Julio Rodriguez drove in two runs for Seattle, yet the Mariners could not sustain pressure once the Athletics’ relievers took over.

The win moved Oakland to 55-86 and left Seattle at 66-75, a result that underscored the difference between an offense that kept adding pressure and one that stopped producing after its opening burst. For the Athletics, the formula is clear: timely contact from Butler and McNeil, power from Walton and a strikeout-oriented bullpen can turn early deficits into wins. Seattle must find more consistent at-bats beyond Rodriguez and prevent promising starts from dissolving into late-inning losses.
