Athletics

Contreras will enter Athletics camp vying for a spot in their bullpen after making 14 relief appearances for the Astros over the past two seasons, finishing with a lackluster 7.50 ERA (4.15 FIP) and 19/10 K/BB ratio across 18 innings. The 29-year-old righty has a lengthy track record of missing bats in the upper minors and represents a low-risk lottery ticket.

Stefanic was with the Blue Jays last season, going just 4-for-22 at the big league level and hitting .287/.403/.383 with six home runs and six steals in 106 games at Triple-A. He figures to serve as organizational depth for the Athletics, given his ability to play everywhere on the infield.

Bido, 30, was successful in 2024 with a 3.47 ERA for the Athletics, but struggled in 2025 with a 5.87 mark over 79 2/3 innings. The right-hander will have a chance to earn a spot on the Atlanta staff in spring training.

Anderson bolsters the Athletics’ relief depth heading into next season after struggling to a bloated 6.14 ERA across 14 2/3 innings over 12 appearances for the Rockies last year. he 35-year-old once profiled as a legitimate late-inning weapon during his Rays days, but the swing-and-miss stuff has faded in recent years. He’ll compete for a spot in the Athletics’ bullpen during spring training.

Suero, who debuted with the Nationals back in 2018, spent time in the Braves and Mets pen last season, though he gave up eight earned runs in 5 1/3 innings for Atlanta and never actually made an appearance in two brief stints with the Mets. He has a 4.96 ERA in 196 career major league appearances, all of them coming in relief.

Krook also signed a minor league deal with the A’s about this time last year. He joined the major league team briefly in May and allowed two runs in 3 1/3 innings before being claimed on waivers by the Guardians. He spent the rest of the year in Triple-A, posting a 3.18 ERA and a 40/24 K/BB in 34 innings. Poor control has kept Krook from establishing himself in the majors, but he can both miss bats and generate grounders. He’ll probably get another look at some point.

The financial terms for the deal are not yet available. Waldichuk missed all of 2025 while recovering from Tommy John surgery, and assuming good health, should be an option in the back of the A’s bullpen in 2026.

No word on how much Medina will get in 2026. The 25-year-old right-hander missed all of 2025 while recovering from Tommy John surgery, but should be an option for the A’s rotation at some point this spring/summer.

This was no surprise after Bleday was designated for assignment Tuesday. The 28-year-old hit 14 homers with a .698 OPS, and likely will sign on as a bench option for a new club this winter.

Hartlieb made four relief appearances between the Tigers and Yankees last season before finishing the year in the Royals’ system. The well-traveled 31-year-old journeyman will compete for a spot in the Athletics’ season-opening bullpen during spring training.
