Marlins Claim Osvaldo Bido

The Marlins have claimed right-hander Osvaldo Bido off waivers from the Rays, reports Daniel Alvarez Montes of El Extra Base. Tampa Bay designated Bido for assignment last week. Miami has an open spot on the 40-man roster after trading lefty Ryan Weathers to the Yankees, so a corresponding move won’t be necessary.

Bido turned 30 this past October. He spent seven seasons in the minors with the Pirates prior to making his debut as a 27-year-old rookie in 2023, and he’s spent the past two seasons pitching with the A’s, who signed him to a big league deal in the 2023-24 winter after Pittsburgh cut him loose. The wiry 6’3″, 175-pound righty has had an up-and-down run in the majors across the past three seasons, posting ugly numbers in 2023 and 2025 but logging 63 1/3 innings of 3.41 ERA ball with solid rate stats in 2024.

Overall, Bido has pitched 193 2/3 innings as a big leaguer. In that time, he carries a collective 5.07 earned run average. Metrics like SIERA (4.60) and FIP (4.67) are a bit kinder, but he’s pitched like a serviceable swingman/sixth starter for much of his time in the league. Bido averages 94.7 mph with both his four-seamer and sinker. His strikeout rate (20.9%) and walk rate (9.6%) are both worse than league average, but not by much. He’s an extreme fly-ball pitcher but hadn’t been especially prone to home runs until the 2025 season — though that was surely due to the Athletics’ temporary home at Sutter Health Park in West Sacramento playing like an absolute launching pad; Bido surrendered 13 home runs in 44 1/3 home innings but just six in 35 1/3 frames on the road.

Bido is out of minor league options, so he’ll need to either break camp with the Fish — presumably in a long relief role — or else clear waivers before he can be sent to Triple-A. Miami has been on the lookout for some rotation depth after trading not only Weathers but also righty Edward Cabrera. Bido provides some for the time being, but an out-of-options journeyman coming off a 5.87 ERA is far from a lock to stick on the roster.

At the moment, Miami’s rotation will include Sandy Alcantara, Eury Perez and (health-permitting) Braxton Garrett. There’s no shortage of other arms to compete for starting jobs. Former top prospect Max Meyer will be healthy after a long injury layoff. Janson Junk, like Bido, came to the Marlins as a journeyman long reliever last year but pitched well enough to carve out a spot on the big league roster in ’26 — whether as a starter or swingman. Righty Ryan Gusto, acquired last July for Jesus Sanchez, offers a similar skill set. Former top prospects Dax Fulton and Adam Mazur have missed time with injury but should be healthy and in the mix for innings. Most notably, top prospects Thomas White and Robby Snelling — two of MLB’s most highly regarded left-handers — are both on the cusp of the majors.

There’s plenty of talent in the mix for Miami’s rotation but also a lot of injury risk and uncertainty. It wouldn’t be a surprise to see them bring in a veteran starter, even if only on a non-roster invitation to spring training, in order to add some stability to the current group.
