The Seattle Mariners and Oakland Athletics are set to clash at T-Mobile Park, opening a three-game series on April 20, 2026. Expectations were mixed before this matchup. The Mariners had just come off a crucial series win against the Rangers, while the Athletics were trying to find their footing after an inconsistent start to the season.

On the mound, Emerson Hancock (2-1, 2.28 ERA) will take the start for Seattle, while J.T. Ginn (0-0, 3.31 ERA) is expected to pitch for Oakland. This matchup presents a decisive moment for both teams—Hancock’s solid performance could help lift the Mariners back into contention.
