The Braves selected the right-hander Osvaldo Bido by assignment, according to the group’s announcement. The right hand Ian HamiltonTriple-A Gwinnett’s contract was selected in the corresponding move. Atlanta also selected a southpaw reliever Hayden Harris in Gwinnett. That would clear another roster spot for the veteran lefty Martín Pérez. Braves captain Walt Weiss said last night that Pérez, who immediately re-signed to a minor league deal after being designated for assignment and waivers, will start on Friday.
Bido, 30, has become the guy on the endless DFA carousel that other players ride on in today’s game. Since the end of the 2025 season, he has been there six separate 40-man rosters with a series of DFAs and waiver claims. He spent the 2025 season with the A’s and has bounced around the Braves, Rays, Marlins, Yankees, Angels and back to the Braves. He may now find himself with a seventh organization in about five calendar months.
On the other hand, the DFA parade may suggest that teams feel that Bido is the league’s biggest arm. On the other hand, you will still go through the cancellation. 20 percent of the league has fielded Bido since the start of the 2025 Winter Meetings. The clubs clearly think there is a big league opportunity for the right-hander, but they have yet to put things together with any real consensus.
Bido pitched 10 innings against Atlanta and scored seven runs on seven hits and five walks. Walking five of the 41 batters he faced (12.2%) was already a problem, but Bido also struck out two batters and threw four wild pitches. Suffice it to say, his command did not exist in 2026.
Command has never been a strong point for Bido, but he hasn’t struggled at this level in the past. He entered this season having walked or struck out 12% of the batters he faced in the finals. He averaged a wild pitch every 10 or more innings. He’s walked/struck out 17.1% of his opponents this year and averaged a wild pitch every two and a half innings – not bad at all.
Bido has had an up-and-down run at the top levels, notching bad numbers in 2023, a strong performance in 2024 and further struggles in 2025. The 2026 season obviously hasn’t been kind to him. Overall, metrics like SIERA (4.62) and FIP (4.70) see him more favorable than his career 5.13 ERA, but Bido often pitches as a pitcher or sixth starter. He averages 94.7 mph on his four-seamer and sinker alike. He’s worse than average in terms of strikeout rate (20.6%) and walk rate (9.7%), but he’s an extreme fly-ball hitter whose best season was spent throwing home games in the cavernous Oakland Coliseum during the Athletics’ final season there.
Last year’s move to Sutter Health Park in West Sacramento, which served as a launch pad, did nothing for Bido. He has used 13 big flies in just 44 1/3 innings at home, compared to just six on the road (35 1/3 innings). He hit one home run in his 10 innings with the Braves.
Bido would land in a pitcher-friendly home park rather than with the A’s or Braves. Sutter Health Park was the fifth friendliest home park for left-handed hitters in 2025, according to Statcast’s Park Factors. Atlanta’s Truist Park was just behind, sitting in sixth place in the MLB. Time will tell if that happens. The Braves have five days to trade Bido or place him on waivers. Full waivers are a 48-hour process, so today’s DFA will be resolved in less than a week.
As for Hamilton, he will be ready for a seventh big league season. He pitched 150 1/3 innings for the White Sox, Twins and Yankees in his career, turning in a sharp 3.59 ERA overall. Horrible 2023 season (2.64 ERA, 58 innings) unfairly touches that long career mark; Hamilton had a 4.91 ERA in 14 2/3 innings before that season and has a 4.06 earned run average in 77 2/3 frames since then.
Hamilton, 30, has struck out just over a quarter of his opponents in the majors but also sported an 11.1% walk rate that is nearly three percent north of average. He showed a lower than average tendency (45.9%) and did a good job of avoiding homers and difficult contact in general. His first year with the Braves organization started well, with 6 1/3 innings of two-run ball and a 9-to-1 K/BB ratio at Triple-A Gwinnett.
Like everyone else in the Atlanta bullpen, Hamilton is out of the minor league league. Right now, it’s a southpaw Dylan Lee is the only pitcher you can choose – bullpen or rotation – on the Braves’ major league roster. It’s an unacceptable setup in the modern game, where teams tend to rotate different relievers in the bullpen to keep a stock of fresh arms to support starters who rarely work deep into games. That’s even more true given that Lee, while technically eligible, isn’t likely to be sent down anytime soon. He has been one of Atlanta’s most successful relievers since 2024, with a 2.65 ERA overall and a 1.13 ERA over his first eight frames in 2026.
