After a brutal White Sox debut, there’s little justification for keeping Osvaldo Bido on the active roster any longer.
Osvaldo Bido, a 30-year-old right-handed pitcher, got into his first game with the Chicago White Sox on Tuesday night. And it’s already clear the Sox need to cut him loose.
Bido was claimed by Chicago on waivers from the Atlanta Braves on April 18. In bringing him in, the White Sox added a relief arm who could be stretched out over multiple innings—a potentially valuable asset for a team with an already depleted bullpen in April.
From 2023–2025, Bido served as a swingman for the Pittsburgh Pirates and Athletics, occasionally working in the starting rotation and at other times handling long relief duties.
His best season came in 2024, when he posted a 3.41 ERA over 63.1 innings with strong underlying metrics. But in 2025, Bido completely fell apart. He finished with a 5.87 ERA and a 1.61 WHIP for the Athletics, and the underlying numbers backed up the surface-level results suggesting he was one of the worst pitchers in baseball.
It hasn’t been much better in 2026.
In six bullpen outings for the Braves, Bido threw 10 innings with a 6.30 ERA—hence why he was designated for assignment and made available for the White Sox to claim.
And in his White Sox debut on Tuesday, he needed 53 pitches just to get through two innings. The Diamondbacks tagged Bido for three hits, four walks, and three earned runs in those two frames, and he nearly turned a blowout victory into a save situation for another White Sox reliever.
The entire purpose of a multi-inning “mop-up” arm is to preserve the rest of the bullpen in low-leverage situations. The White Sox can’t afford to carry a pitcher with control issues who turns comfortable wins into nail-biters.
At this point, there’s no real reason for the White Sox to keep Bido around.
If Chicago wants a multi-inning reliever who can provide length, they could simply recall Duncan Davitt, who debuted on April 10 before being optioned back to Triple-A immediately afterward.
Davitt is 26 years old and already on the 40-man roster, but he doesn’t currently have a path into the starting rotation with all the pitching talent coming up through the organization. Still, he could stick with the White Sox for years if he proves capable of getting outs at the big league level, and he’s shown plenty of promise in the minor leagues to justify that opportunity.
There’s nothing Bido does that Davitt can’t. I’d argue Davitt is actually better suited to make an immediate impact in a multi-inning relief role—if for no other reason than he’s far less likely to issue 6.8 walks per nine innings like Bido has so far this year.
Of course, that’s just one option. And frankly, I don’t really care who the White Sox bring up to replace Bido—as long as he’s no longer on the roster.
If he’s not going to do his job, the White Sox need to give that MLB roster spot to a more deserving young player who’s hungry for the opportunity.
