Thomas Pannone: Everything you need to know

Pannone (forearm) struck out a batter and allowed three hits and no walks over three scoreless innings Thursday in his season debut for Triple-A Nashville after being reinstated from the 7-day injured list. Pannone sustained a left forearm flexor strain last spring and spent the entire 2025 campaign on Nashville's IL, and though his rehab bled into the start of 2026, he missed just a few weeks of the Triple-A season before slotting back into the rotation. The southpaw will serve as organization depth for the Brewers this season, but his lack of a 40-man roster spot makes it unlikely that he'll see action with the big club at any point.

Pannone was diagnosed with a torn flexor tendon in his left forearm Saturday, Adam McCalvy of MLB.com reports. The 30-year-old suffered the injury last weekend and will be shut down from throwing for at least one month. Pannone could miss the first couple months of the season before taking the mound for Triple-A Nashville.

Pannone left during the first inning of Sunday's spring game against the Guardians due to a forearm injury, Adam McCalvy of MLB.com reports. Pannone struggled in his short outing Sunday, during which he allowed four runs (three earned) on six hits and one walk across just 0.1 innings before being pulled. He'll be evaluated over the coming days to determine the severity of the injury, but it's a setback in Pannone's quest of breaking into the Brewers' rotation following a solid 2024 season in Triple-A in which he posted a 3.54 ERA and 136:38 K:BB over 152.1 innings.
