Corbin Burnes (shoulder) throws bullpen session

Burnes was shut down from throwing in early June after suffering a teres major strain. He had a follow-up MRI over the All-Star break, which showed positive healing, and he has begun his throwing program again. Until he progresses enough to begin throwing full bullpens, it’s hard to predict any kind of timeline for his return. At this point, it would be unlikely he makes more than one or two appearances for the Diamondbacks this season.

Lovullo added that Burnes suffered a teres major strain in his shoulder during a recent live batting practice session and is unlikely to return until September following the setback. The 31-year-old former fantasy ace, who was working his way back from last year’s Tommy John surgery, was on track to return to Arizona’s rotation sometime around next month’s All-Star break. It’s an extremely tough development for the Diamondbacks and fantasy managers that were stashing Burnes for a potential second-half impact. There should be a clearer return timetable once he’s cleared to resume throwing.

Burnes is making steady progress towards rejoining Arizona’s rotation sometime in the second half of the season after undergoing Tommy John surgery last year. The 31-year-old former fantasy ace will face hitters a couple times before he’s cleared to head out on a minor league rehab assignment at some point in June.

Burnes continues working his way back from last year’s Tommy John surgery and figures to be ready to rejoin Arizona’s rotation at some point in the second half. The 31-year-old former fantasy ace’s next big hurdle is progressing to facing hitters in live batting practice as he ramps up his throwing program.

The star 31-year-old right-hander is currently recovering from Tommy John surgery and is tentatively targeting a return around the All-Star break. This was done primarily as a procedural move to free up a spot on the team’s 40-man roster to make the Zac Gallen signing official on Sunday.

Burnes was saying the same at the end of last season, so he’s apparently made steady progress since. Burnes underwent Tommy John surgery in June, so a July return is fairly aggressive, though hardly unprecedented. The 31-year-old is entering the second season of a six-year, $210 million contract.

Burnes underwent Tommy John surgery in early June, so this is not an unexpected timeline. Shane Bieber was on a similar timeline last year before a setback delayed him, so fantasy managers can draft Burnes with the same confidence or expectations that they had for Bieber coming into the 2025 season.

The procedural move frees up a spot on Arizona’s 40-man roster for backup catcher Aramis Garcia. Burnes is set to undergo season-ending Tommy John surgery on Wednesday and will likely be sidelined until the second half of the 2026 campaign. The 30-year-old ace was in the first season of a six-year, $210 million contract with the Diamondbacks.

Ugh. The worst-case scenario was always a potential outcome once Burnes went for a second opinion on his elbow. Diamondbacks manager Torey Lovullo confirmed the decision on Friday to reporters that Arizona’s ace will undergo reconstructive surgery. The 30-year-old right-hander, who is in the first season of a six-year, $210 million contract with the Diamondbacks, will miss the remainder of the 2025 season and most of the 2026 campaign as well while recovering from the procedure. It’s just an absolutely brutal blow to both the Diamondbacks and to fantasy managers. Ryne Nelson should now have extra runway to stick around in the club’s starting rotation.

Burnes, who was hurt during his start Sunday, is getting a second opinion on his elbow after initial tests failed to produce a definitive diagnosis. Ryne Nelson is taking his spot in the Arizona rotation. Burnes is 3-2 with a 2.66 ERA in 11 turns this season. He missed one start last month due to shoulder inflammation.
