Following a loss last night after coughing up a three-run lead, the Mariners are hoping to even the series against the Athletics on Tuesday night.
Castillo Seeks First Win
Luis Castillo will start for the M’s, still looking for his first win of 2026 in his fifth start. Castillo has a 5.40 ERA this season. His 3.30 FIP suggests some bad luck.
Last time out in San Diego, Castillo allowed quite a bit of hard contact for one earned run over 5.1 innings. He gave up four runs in total, all of which came during an ill-fated second inning in which he made an error on a throw to Josh Naylor at first that maybe should’ve been picked, making three of the runs unearned. No one is accusing the Mariners infield of putting on a defensive clinic lately, but Castillo didn’t exactly look sharp either. He’ll look to bounce back in the friendly confines of T-Mobile Park.
Athletics’ Pitching and Mariners’ Lineup
The Athletics will counter with Jacob Lopez (1-1, 6.38 ERA), who is also making his fifth start of the season. The Mariners are rolling out their righty platoon to face the lefty Lopez. Cal Raleigh will get a DH day while Mitch Garver is behind the dish. With Rob Refsnyder in the lineup batting leadoff, J.P. Crawford slots down to sixth.
Roster Moves: Legumina Designated, Hoppe Recalled
The Mariners designated RHP Casey Legumina for assignment in the aftermath of his losing decision last night. RHP Alex Hoppe was recalled from Triple-A Tacoma and will join the Mariners bullpen as a corresponding move. His first appearance will be his major league debut.
The game will be broadcast on Mariners.TV, with Aaron Goldsmith, Ryon Healy and Ryan Rowland-Smith. Radio coverage is on 710 AM Seattle Sports, with Rick Rizzs and Gary Hill Jr.
