White Sox Designate Osvaldo Bido For Assignment

The White Sox have designated right-hander Osvaldo Bido for assignment, per a club announcement. His spot on the roster will go to southpaw Tyler Schweitzer, who’s being recalled from Triple-A Charlotte.

Incredibly, this is the sixth DFA for Bido since mid-December — to say nothing of a seventh time he was placed on waivers in early December went went from the A’s to the Braves. In essence, that’s seven DFAs in a span of five months.

That may make Bido seem like an unwanted player, but the fact that he continues to land on major league rosters despite being out of minor league options is a clear indicator that big league evaluators think there’s another level to be unlocked in the wiry right-hander. Since Dec. 5, he’s gone from the A’s to the Braves, to the Rays, to the Marlins, to the Angels, to the Yankees, back to the Braves and finally to the White Sox. Despite hitting waivers seven times — soon to be eight, unless he’s traded first — he’s never once passed through waivers unclaimed.

Bido, 30, has pitched 18 2/3 innings between Atlanta and Chicago this season. In that time, he’s been tagged for 13 runs (6.27 ERA) on 15 hits and 10 walks with 11 strikeouts. He’s also plunked four batters and tossed four wild pitches. It’s the second straight season of unsightly results; Bido served up a 5.87 ERA in 79 2/3 innings as a swingman with the A’s in 2025 as well.

Back in 2024, the 6’3″, 175-pound righty logged 63 1/3 innings with a 3.41 ERA for the A’s in their final season in Oakland. He set down 24.3% of his opponents on strikes, issued walks at a 10% clip and did an outstanding job avoiding hard contact (85.6 mph average exit velocity, 27% hard-hit rate).

Bido spent seven seasons in the Pirates system before making his MLB debut as a 27-year-old in 2023. In 212 1/3 major league innings, he’s posted a 5.17 ERA (4.67 SIERA, 4.81 FIP). He’s an extreme fly-ball pitcher who’s shown passable but not great command and missed bats at a slightly below-average level. Bido averages 94.7 mph on his four-seamer and sinker alike, coupling those heaters with an 86 mph slider and a lesser-used, upper-80s changeup.

The White Sox have five days to trade Bido, place him on outright waivers (a 48-hour process) or release him. If they can finally be the team to pass him through waivers, he’ll head to Triple-A Charlotte, as Bido lacks the prior outright or three years of service time needed to reject a minor league assignment in favor of free agency.
