Osvaldo Bido is a Major League baseball pitcher that you may have heard of. Particularly if you are the type of person that monitors the transactions logs.
Bido, a right-handed pitcher from the Dominican Republic, has three years of Major League game time under his belt, but a fourth consecutive year is proving hard to come by. He has been all over the transaction logs this winter on account of having been designated for assignment five times in a single offseason – a total that, as best as can be established, ties an all-time record.
In just the gap between the end of the 2025 season and today – a span of barely three months – Bido has passed through the hands of each of the Athletics, Atlanta Braves, Tampa Bay Rays, Miami Marlins and Los Angeles Angels. At the time of writing, he remains on waivers from the Angels’ designation, and may have at least one more flying visit left in him. And if he does, he will surpass Lewin Diaz’s ignominious record.
Former A’s RHP Osvaldo Bido has now been designated for assignment for the 5th time in the last 2 months. First by the A’s, then by the Braves, then by the Rays, then by the Marlins, and now by the Angels. Just call him Mr. 41!

Bido’s Late Start
Bido debuted in Major League Baseball relatively late. Signed as an international free agent by the Pittsburgh Pirates in March 2017, he spent seven seasons in the minor leagues before his first MLB call-up. He eventually made his major-league debut on June 14 2023, at age 27, starting a game in which he threw 4.0 innings, allowed 4 hits, struck out 6, walked 3, and gave up 1 earned run. It was a fair microcosm of his career to date.
Across his three MLB seasons to date, Bido has appeared in 58 games, including 28 starts, and compiled a 9–13 win-loss record with a 5.07 ERA and a 1.41 WHIP over 193.2 innings. He has allowed 191 hits and 82 walks while striking out 179 batters in that span, below MLB average in both run prevention and contact suppression, albeit with a solid 2024 campaign on a bad Athletics team.
In his debut year of 2023 with the Pirates, Bido went 2-5 with a 5.86 ERA, threw 50.2 innings, struck out 48 and walked 21. In 2024 with the then-Oakland Athletics, he posted a 5-3 record with a 3.41 ERA, a 1.09 WHIP, 63.1 innings, 63 strikeouts and 26 walks, including posting a truly excellent month of August that ranked amongst the best in baseball before an injury interrupted his campaign. In 2025, though, he returned to the Athletics and appeared in 26 games with 10 starts, but went only 2-5 with a 5.87 ERA, a 1.61 WHIP, 79.2 innings, 68 strikeouts, and 35 walks, and notching one save. So began the shuffle.
Like so many others before him, Bido has been in the churn between the Triple-A and Major Leagues, on account of having four decent pitches that he does not sufficiently command. Of all those others before him, though, only Diaz has been through the DFA process quite this much.

Back On Waivers Once Again
The journey began in early December 2025, as Bido was designated for assignment for the first time by the Athletics after finishing the 2025 season with his 5.87 ERA. Over the ensuing weeks, the Braves claimed him on December 5, then the Rays claimed him and DFA’d him within days after making a trade for another fellow Athletic starter in Ken Waldichuk. Next, the Marlins would claim him on January 16 before within days once again designating him, before finally the Angels claimed him, before they too traded for a different arm in Jayvien Sandridge and needed the 40-man spot that the option-less Bido was taking up.
All four franchises had hoped that with his good stuff, Bido would clear waivers, and be an in-season option should he develop his command any. None of these teams are competing for the World Series, and all were hoping to buy low on someone with resale value. At least four of them, though, were wrong. And the Angels may soon be the fifth.
Bido’s tally of as it stands five DFAs matches the modern high mark set by Diaz, who had a similarly busy winter of 2022. The big first baseman – once a prized prospect of the Minnesota Twins – would pass through each of the Marlins, Pirates, Baltimore Orioles and Braves before winding up back up with the Orioles for the 2023 season. He would however never quite click at the plate at the majors level, and now plays in Korea. That move is not yet necessary for Bido, who clearly has MLB suitors, albeit on a conditional basis.
Being designated for assignment five times in one offseason does not automatically disqualify a player from going on to achieve good things, but it does underscore the volatility that fringe pitchers can experience. Teams frequently use waivers and DFA transactions to manage 40-man roster space, particularly in the winter months when trades, signings and Rule 5 considerations put pressure on available spots. A pitcher like Bido, who profiles as organizational depth at this age but without the consistency to turn it into regular work, is especially susceptible to that turnover. Maybe next time.
