Diamondbacks' Corbin Burnes: Feels good following session
Rotowire
Burnes (elbow) began a throwing program July 10 and felt good following the session, MLB.com reports.
Burnes had been working his way back from Tommy John surgery during April and May but was forced to shut down in early June. The plan calls for him to throw off flat ground every other day and then progress to throwing off a mound. The Diamondbacks hope the right-hander can return in time for a September playoff push.

Diamondbacks' Corbin Burnes: Cleared to throw
Rotowire
Burnes (elbow/side) was cleared to begin a throwing program Friday after an MRI showed signs of healing, Nick Piecoro of The Arizona Republic reports.
Burnes has been on the injured list since June 2025 while recovering from Tommy John surgery, though his time on the shelf was extended when he suffered a teres major strain while throwing to live hitters last month. Now that he's made encouraging progress in his recovery from both injuries, he's been given the green light to restart a throwing progam. It will take him a while to ramp up after missing more than a full season, though the team hasn't yet shut the door on Burnes returning before the end of the year.

Diamondbacks' Corbin Burnes: Set for evaluation in early July
Rotowire
Arizona manager Torey Lovullo said Monday that Burnes is expected to receive follow-up imaging on his elbow in the first or second week of July, Alex Weiner of ArizonaSports.com reports.
After facing hitters May 29 for the first time since undergoing Tommy John surgery June 11, 2025, Burnes reported discomfort following the workout and was diagnosed with a teres major strain. He'll remain shut down from activity for at least another week or two, but he could be cleared to resume a throwing progression if his imaging shows improvement. Burnes will presumably need a lengthy ramp-up period once getting the green light to throw, so he would appear unlikely to make it back from the 60-day injured list until the second half of August or possibly September.
Manager Torey Lovullo said Wednesday that Burnes (elbow) has been shut down from throwing after suffering a teres major strain, Bob Nightengale of USA Today reports.
Burnes has been throwing to live hitters over the past couple of weeks while working his way back from a Tommy John procedure he underwent last June, and he reportedly felt something in his side/shoulder during his last session. The team is hopeful that the 31-year-old righty will still be able to return sometime in September, though a more precise timeline will likely take shape once he's cleared to restart his throwing program.

Rotowire
Burnes (elbow) threw to a hitter Friday for the first time post-surgery, MLB.com reports.
The rehabbing Burnes faced the rehabbing Jordan Lawlar (wrist), marking the first time either player has faced a live opponent during their respective recoveries. Next up for Burnes is another batting practice session Tuesday. The right-hander is expected to return midseason, likely following the All-Star break.
Burnes (elbow) is expected to begin throwing live batting practice Friday, Nick Piecoro of The Arizona Republic reports.
Burnes will first have to make it through two more bullpen sessions, but assuming he doesn't suffer any setbacks, he'll be cleared to face live hitters for the first time since undergoing Tommy John surgery last June. The 31-year-old righty said he also expects to begin playing in rehab games in a few weeks and is aiming to make his season debut for the D-backs around the All-Star break.
Burnes (elbow) threw a bullpen session Tuesday, Jose M. Romero of the Arizona Republic reports.
Burnes has been throwing occasional bullpen sessions since spring training -- Tuesday's session was his fourth -- so there was nothing particularly notable about Tuesday's activity. "He just wants to make sure everything is feeling right, he's duplicating his delivery," Diamondbacks manager Torey Lovullo said of Burnes. The pitcher is still on track to return near or after the All-Star break.
Diamondbacks' Corbin Burnes: Adds curveballs in BP session
Rotowire
Burnes (elbow) threw a bullpen session Monday, Steve Gilbert of MLB.com reports.
Burnes threw a second bullpen session and mixed in curveballs after tossing 15 pitches (all fastballs) last Friday. The plan going forward calls for the right-hander to pitch again this coming Friday, and to then complete two sessions per week for the next month while incorporating all his pitches. At the moment, Burnes is estimated to be throwing at about an 80-to-85 percent effort level.
