White Sox Outright Osvaldo Bido

May 9th: Bido has been sent outright to Triple-A Charlotte, per Brooke Fletcher of Chicago Sports Network.

May 8th: 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 and 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.

White Sox Option Shane Smith, Promote Tyler Schweitzer

The White Sox sent right-hander Shane Smith to Triple-A, the team announced. Left-hander Tyler Schweitzer was promoted to the big-league club. To clear a 40-man roster spot for Schweitzer, outfielder Brooks Baldwin was moved to the 60-day IL. Baldwin recently underwent an internal brace procedure and is expected to miss the entire season.

Smith was knocked around for 10 earned runs over 8 2/3 innings across three outings to begin the season. He tossed 3 2/3 scoreless frames against the Orioles on Tuesday, but it was far from an effective outing. Smith walked five and threw just 57 of his 99 pitches for strikes. He was able to dance around the traffic on the bases with the help of eight strikeouts, but the erratic showing ultimately cost him his roster spot.

It’s a swift fall from grace for Smith. The former Rule 5 pick was one of the few success stories from a forgettable 2025 campaign. The righty broke camp with the team and hit the ground running, allowing three earned runs or less in 13 straight starts to open the season. Smith faded as the innings piled up, but finished the year with a solid 3.81 ERA with just under a strikeout per inning.  The solid effort earned Smith an All-Star selection and the Opening Day nod for 2026.

Smith hasn’t been hit particularly hard during this difficult three-start run, but he’s struggled to consistently find the strike zone. The righty has now issued nine free passes following Tuesday’s five-walk performance. He had similar challenges in MLB Spring Training, walking nine over 10 2/3 innings. Smith has frequently fallen behind opposing hitters, posting a 51% first-pitch strike rate. That mark was 60.4% in 2025. Heading to the minors will give him a chance to iron out the control issues.

Schweitzer was selected in the fifth round of the 2022 draft. The lefty has steadily moved up the minor league ladder, reaching Triple-A by the end of last season. Schweitzer’s stint with Charlotte didn’t go so well (7.92 ERA over 50 IP), but he got off to a better start this year. The 25-year-old allowed just one earned run over five frames with the Knights before getting called up.

MLB Pipeline ranks Schweitzer at No. 23 among Chicago’s prospects. The southpaw boasts a mid-90s heater that reaches 98 mph, along with a changeup, slider, and curveball. MLB Pipeline’s scouting report identified the changeup as Schweitzer’s best pitch, given its movement and deception.

James Fegan of Sox Machine first reported Smith’s demotion. Elijah Evans of Just Baseball was first to report Schweitzer’s promotion.
