SEA Mariners @ Athletics - Money Line - SEA Mariners Win - 2026-05-27 15:05:00 for Today, 05/27/26

The Seattle Mariners and the Athletics wrap up a three-game series at Sutter Health Park in West Sacramento on Wednesday night. Seattle is going for the series sweep, too, posting a 9-2 win on Monday night behind veterans RHP Luis Castillo and RHP Bryce Miller, while easing by the A’s 4-1 on Tuesday night as slight underdogs, as RHP Emerson Hancock twirled six innings of scoreless baseball, allowing just a single hit with two walks in an 87-pitch quality start. The Mariners will send RHP Logan Gilbert to the hill, as Seattle looks to cap off the series sweep. Gilbert has managed a 1.19 ERA (22.2 IP, 3 ER) in 22 2/3 IP across four road outings this season, as he has been ace-like away from home.

The A’s send LHP Jeffrey Springs to the hill, looking to salvage the finale. He has had issues on his home mound, going 2-3 with a 4.60 ERA with six homers allowed in just 31 1/3 IP. The Mariners are just 8-9 this season against left-handed starting pitchers, so don’t get carried away here. However, with first-place on the line, with Seattle just a half-game back, look for the division lead to change hands, as the Mariners sweep the A’s.

Mariners ML (-105) at time of publishing. Playable to -120.
