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.

Puk (elbow) is asymptomatic, Alex Weiner of ArizonaSports.com reports.

EDGE Analysis

Puk has been sidelined since April 19 and was then shifted to the 60-day injured list May 1. While he'll still face an extended absence, it's a positive sign that he's no longer feeling significant pain in his elbow.

The Diamondbacks transferred Puk (elbow) from the 15-day injured list to the 60-day IL on Thursday.

EDGE Analysis

The move frees up a spot on the 40-man roster for right-hander Jose Castillo, whose contract was selected from Triple-A Reno on Thursday. Puk is dealing with a left flexor strain, and while he will not undergo surgery at this time, he is facing an extended absence. Justin Martinez (shoulder) was also placed on the IL on Thursday, so the Diamondbacks are down their top two relievers and could turn to Ryan Thompson, Shelby Miller and Kevin Ginkel as options to close games.

Puk will not undergo surgery to repair his left elbow flexor strain, Nick Piecoro of The Arizona Republic reports.

EDGE Analysis

Although Puk won't be going under the knife, he's still expected to miss quite a bit of time. The plan is for him to pause all throwing for the next 2-to-3 weeks, at which point the D-backs will re-evaluate him and determine next steps. Justin Martinez will act as Arizona's primary closer while Puk is out.

Puk (elbow) is unlikely to pitch for at least a couple of months, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

The Diamondbacks have not officially announced a timeline for Puk, who is awaiting word from two orthopedic doctors as to the severity of his elbow injury. However, team officials have spoken as if they are preparing for Puk to be sidelined for a lengthy period, and potentially the rest of the season. His absence will likely solidify Justin Martinez's role as the closer, though Kevin Ginkel (shoulder) is also nearing a return.
