Miami Marlins AAA
2026 Fantasy Outlook
Bido bounced around via waivers from the Athletics to Atlanta and then Tampa Bay in the offseason. The right-hander had an unsightly 5.87 ERA and 18.7 percent strikeout rate in 2025, but he was much better in 2024 with a 3.41 ERA and 24.3 percent strikeout rate. Bido does not have minor-league options left, but he offers the flexibility to be used either in a starting or relief role. He'll likely be fighting for a low-leverage relief role with the occasional spot start, but perhaps the Rays can work their magic and get something more out of him. Read Past Outlooks
$Signed a one-year contract with the Athletics in March of 2025. Claimed off waivers by Atlanta in December of 2025. Claimed off waivers by the Rays in December of 2025. Claimed off waivers by the Marlins in January of 2026.
Removed from 40-man roster again
PMiami Marlins  AAA
January 20, 2026
The Marlins designated Bido for assignment Tuesday.
Analysis
The transaction clears a spot on the 40-man roster for the addition of Bradley Blalock. Bido has already been in four organizations this offseason and could make it a fifth if he gets claimed on waivers again. He held a 5.87 ERA and 18.7 percent strikeout rate in 2025 with the Athletics.

Past Fantasy Outlooks
2025
2024
Bido proved to be a nice addition for the A's after he was non-tendered by the Pirates in November of 2023. He made 16 appearances between the rotation and bullpen, pitching to a 3.41 ERA and 1.09 WHIP over 63.1 MLB innings before right wrist flexor tendonitis ended his season. He had an 11.81 ERA the third time through the order, which leaves open the distinct possibility that his future lies in the bullpen. His four-seamer, slider, changeup and cutter all had xBAs under .200 last season, and with that kind of repertoire, the book is not closed on Bido starting. Despite the team context, Bido might be worth a flier to see if he can break camp with a rotation spot.
Bido made his big-league debut in his age-27 season with the Pirates in 2023, though he didn't find much success in a split role between starting and relief. He relies primarily on a fastball, slider and sinker, but he doesn't generate many swings and misses and has only a moderate groundball rate. That leaves Bido without a clear path to getting outs. After the close of the 2023 season, he was non-tendered by the Pirates but quickly struck a deal with the Athletics. That gives him a legitimate shot at a roster spot out of spring training, with the benefit of playing in one of the more spacious home parks around the league. He could be a streaming option in good matchups, but that's the best-case scenario entering 2024.

Latest Fantasy Rumors
Could debut Monday
PPittsburgh Pirates  AAA
June 26, 2022
Bido is a possibility to start Monday's game in Washington, reports Mike Persak of the Pittsburgh Post-Gazette.
Analysis
The Pirates have yet to announce who will start Monday's game, but Bido would be available to pitch on full rest. The other option would be a bullpen game. If called upon, Bido would be making his major-league debut. The 26-year-old has struggled with command and giving up the long ball this season and has a 4.86 ERA with 10 homers allowed and a 46:36 K:BB in 50 innings for Triple-A Indianapolis.
