The Oakland Athletics and Seattle Mariners engaged in a series of matchups in early September 2026.

Initially, the Athletics secured two consecutive victories against the Mariners. In one 7-4 win, Lawrence Butler drove in the go-ahead run, supported by 18 combined strikeouts. In a subsequent 7-6 victory, the Athletics became one of only two Major League teams that season to hit four home runs in a single inning, featuring home runs from Zack Gelof, Max Muncy, Alika Williams, and Jeff McNeil.

The Mariners later responded with a 2-0 victory, avoiding a four-game sweep. Starting pitcher Bryan Woo pitched eight shutout innings, allowing only one hit and striking out nine.
