Athletics Option Osvaldo Bido, Designate Jason Alexander For Assignment

By Anthony Franco | May 16, 2025 at 5:28pm CDT

The A’s made a few moves on the pitching staff before tonight’s series opener in San Francisco. They selected relievers Anthony Maldonado and Matt Krook into the big league bullpen. They’ll take the roster spots of righties Osvaldo Bido and Jason Alexander. Bido was optioned to Triple-A Las Vegas, while Alexander was designated for assignment. They only needed to open one 40-man roster spot, as they still had a vacancy after returning Rule 5 pick Noah Murdock to Kansas City last week.

The pitching staff took a beating yesterday. The Dodgers put up 19 runs. Bido and Alexander took most of the damage. Bido started the game but was unable to escape the second inning, allowing six runs. Alexander was the first man out of the bullpen. He had an even tougher time, allowing nine runs on seven hits (including a trio of homers) and four walks across 2 1/3 frames. Mitch Spence took the next three innings before backup catcher Jhonny Pereda got a mop-up frame.

Bido has operated as Mark Kotsay’s fifth starter all season. He’d pitched well in a swing role last year, turning in a 3.41 ERA through 63 1/3 innings. This year has been a struggle. Bido has allowed 5.82 earned runs per nine over 43 1/3 frames. His strikeout rate has plummeted from a solid 24.3% mark to this year’s 14.6% clip. He has surrendered 10 home runs, more than two per nine innings. Bido has yet to complete six innings and has allowed four or more runs in all but one of his last five starts.

That kind of production clearly isn’t cutting it. The A’s don’t have an off day until Memorial Day. They’ll need to find another starter to operate behind Luis Severino, Jeffrey Springs, Gunnar Hoglund and JP Sears. That might be J.T. Ginn, who has been out for three weeks with elbow inflammation. He tossed 64 pitches in a rehab start in Las Vegas on Wednesday and might make his next start in the big leagues.

Alexander loses his 40-man roster spot entirely. The A’s had signed him to an offseason minor league deal and selected his contract two weeks into the season. He has given up 13 runs (12 earned) in six innings over four MLB appearances. Alexander has been far better over five Triple-A starts: a 1.27 ERA with a 23.6% strikeout rate and massive 63.6% grounder percentage across 21 1/3 frames.

Maldonado and Krook were offseason acquisitions who’ll be in line for their team debuts. The 27-year-old Maldonado debuted with 19 innings of 5.68 ERA ball for the Marlins last year. The A’s claimed the righty off waivers early in the offseason and ran him through waivers a few months later. He has been excellent for Las Vegas, reeling off 12 1/3 frames of one-run ball with 17 strikeouts. Maldonado leans most heavily on a mid-80s breaking ball and has a low-90s sinker.

Krook, 30, is a left-hander who has five career big league innings. He signed a minor league deal over the winter. Krook has allowed six runs (five earned) over 14 innings with the Aviators. He has racked up 21 strikeouts but has walked eight batters and hit another. He has gotten an impressive combination of whiffs and ground-balls throughout his minor league career, but that has been undercut by well below-average command.

    You’re giving him the “It’s not him, it’s me” routine!?! He INVENTED “it’s not you it’s him”. If it’s ANYONE, it’s him.

    If Jason Alexander was DFAed because they signed Kevin Newman, THAT would be a story.

    Well, that explains why the Aviators bullpen was so awful last night (They lost, 11 – 4.). For anyone watching the Athletics’ prospect list, don’t expect Mason Barnett to be listed as their #3 prospect much longer. He’s been a dumpster fire all season.
