Sacramento Athletics
2025 Fantasy Outlook
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. Read Past Outlooks

From Preseason

Signed a one-year contract with the Athletics in March of 2025.
Used in bullpen Saturday
PSacramento Athletics
September 1, 2025
Bido struck out a batter and allowed two earned runs on three hits and no walks over 2.1 innings of relief in Saturday's 9-3 loss to the Rangers.
Analysis
Bido made a three-inning start in his last appearance Tuesday against the Tigers, but he shifted back to the bullpen over the weekend and looks poised to serve as a reliever moving forward. Rookie Mason Barnett entered the Athletics rotation Saturday, and Luis Severino (oblique) is set to be activated from the 15-day injured list Tuesday, so the team won't have a starting spot available for Bido.

2024 Fantasy Outlook
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
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.
