Puk (elbow) has begun throwing bullpen sessions off a mound, MLB.com reports.

EDGE Analysis

The sessions are described as "short box," which is when a catcher sets up just in front of home plate. Puk underwent internal brace elbow surgery last June and is expected back sometime around the All-Star break.

The Diamondbacks placed Puk (elbow) on the 60-day injured list Sunday.

EDGE Analysis

The left-hander will be unavailable for at least the first couple months of 2026 while rehabbing from Tommy John surgery, so his move to the 60-day IL is just a procedural move. After reporting for spring training last week, Puk said that he expects to make his season debut before July.

Puk (elbow) said Tuesday that he expects to be ready for his season debut before July, Alex Weiner of ArizonaSports.com reports.

EDGE Analysis

Puk had an internal brace procedure last June rather than a full Tommy John repair of his UCL injury. The less invasive surgery gives him a chance at a quicker return, so a season debut before the All-Star break is possible. The left-hander expects to be cleared to throw off a mound by the end of March, and a clearer picture of his timetable could be available around that time. Puk will have a good shot to assume the closer role in Arizona when he does return, as the Diamondbacks bullpen lacks established options.

Puk (elbow) agreed to a one-year, $3.1 million deal with the Diamondbacks to avoid arbitration Thursday, Jack Sommers of DBacks on SI reports.

EDGE Analysis

Puk was limited to only eight appearances in 2025 and underwent Tommy John surgery in mid-June. He's expected to miss most of 2026, but might be able to contribute in the final couple of months.

Diamondbacks Torey Lovullo told reporters Friday that Puk (elbow) underwent Tommy John surgery Thursday, John Gambadoro of Arizona Sports 98.7 FM reports.

EDGE Analysis

Puk was pulled from his throwing program last week after experiencing left elbow discomfort. He visited Dr. Neal ElAttrache in Los Angeles on Thursday, where it was determined that Tommy John surgery is the best option for the 30-year-old southpaw. Puk will miss the rest of the 2025 season, and given the significance of the procedure, he could miss most -- if not all -- of 2026. He'll end the season with a 3.38 ERA, 1.25 WHIP and four saves across eight innings out of the bullpen.

Manager Torey Lovullo said Puk (elbow) will visit Dr. Neal ElAttrache in Los Angeles on Thursday after experiencing some left elbow discomfort, Steve Gilbert of MLB.com reports.

EDGE Analysis

The 30-year-old had his throwing program paused last week due to the discomfort, and the fact he's visiting a well-known surgeon could be cause for concern. The Diamondbacks will already be without closer Justin Martinez for the rest of the season due to Tommy John surgery, and Puk is now being evaluated for further elbow issues after landing on the shelf with inflammation in mid-April.

Manager Torey Lovullo said Friday that the Diamondbacks have paused Puk's (elbow) throwing program, Nick Piecoro of The Arizona Republic reports.

EDGE Analysis

Puk has been on the injured list since mid-April due to inflammation in his elbow, and he was recently cleared to begin throwing from 120 feet out. However, he's now been shut down from throwing and is scheduled to see a doctor within the next few days. More details on what that might mean for his return timeline will have to wait until after his appointment, but pausing a throwing program rarely leads to good news.

Puk (elbow) has been cleared to throw out to 120 feet, Arizona Sports reports.

EDGE Analysis

Puk, who was placed on the 15-day injured list April 19 due to left elbow inflammation and was shifted to the 60-day IL on May 1, continues to make steady progress in his throwing program. The team still hasn't provided a firm timetable for the southpaw's return, though he's eligible to be activated July 1.

Puk has stretched his throwing program out to 60 feet, Alex Weiner of ArizonaSports.com reports.

EDGE Analysis

Puk has been making slow progress in his recovery from left elbow inflammation, and he'll soon expand his throwing program to 90 feet. The left-hander isn't eligible to return from the 60-day injured list until July 1, so he still has plenty of time to ramp up his activity prior to then.

Puk (elbow) is expected to begin a throwing program in the coming week, Alex Weiner of ArizonaSports.com reports.

EDGE Analysis

Puk was placed on the 15-day injured list April 19 with left elbow inflammation before later being transferred to the 60-day IL on May 1. The left-hander isn't eligible to be activated for over a month, but beginning a throwing program will be the first step in his build up to returning to action down the road this season.
