Diamondbacks reliever A.J. Puk underwent elbow surgery today, manager Torey Lovullo tells the Burns & Gambo show. Puk had visited Dr. Neal ElAttrache after experiencing recurring soreness as he tried to work back from a flexor strain. Lovullo didn’t have specific details as to whether he required a full Tommy John ligament replacement or some kind of modified internal brace procedure. Puk’s season is over in either case. He’s likely to miss most or all of 2026 as well.
Additionally, the manager told Burns & Gambo that catcher Gabriel Moreno has a hairline fracture in his right index finger. The D-Backs placed Moreno on the 10-day injured list yesterday but had initially called it a hand contusion. He has evidently been playing through an undiagnosed fracture for some time. A return timetable is unclear but will be measured in “weeks, not days.” Topping it all off, Nick Piecoro of The Arizona Republic reports that left-hander Tommy Henry is also headed for season-ending elbow surgery.
The news on Puk is terrible but unsurprising. He has been plagued by elbow issues for the past two months. He’d undergone Tommy John surgery once before in his career. The 6’7″ southpaw required the procedure in 2018 when he was a member of the A’s farm system. He missed that season and was limited to 28 combined appearances between the minors and MLB the following year.
Acquired from the Marlins at the 2024 deadline, Puk has been one of the most dominant relievers in the sport since getting to Arizona. He recorded 43 strikeouts in 27 1/3 innings after the trade last summer, working to a 1.32 ERA in the process. He had fanned 12 more hitters against two walks while collecting four saves in his first eight appearances this year. Aside from a terrible stint in Miami’s rotation early last season, he has been generally excellent since the A’s traded him to Miami over the 2022-23 offseason.
Depending on the nature of the surgery, there’s a decent chance this will end his time with the D-Backs. Puk has over five years of MLB service. He’ll be eligible for arbitration for the final time next offseason. He’d earn only a modest raise on this year’s $2.95MM salary, but a full ligament repair would make him a non-tender candidate. Players usually require 14-plus months to return from Tommy John surgery, and that would be Puk’s second such procedure. He’s likely to be out through next year’s All-Star Break even if he “only” needed the internal brace procedure, though the D-Backs would happily retain Puk for around $3MM if they felt they could get half the season from him.
The news on Puk comes a week after Justin Martinez, the team’s other top reliever, also went under the knife. Corbin Burnes and Jordan Montgomery have been Tommy John victims in the rotation. It’s difficult for any team to weather that kind of injury luck. Arizona has hovered around .500 despite having an elite offense because of their issues on the mound.
They’ll lose Moreno from that lineup for what seems like a decent chunk of time. There’s a significant drop off to light-hitting backup Jose Herrera. The Snakes selected Aramis Garcia to work off the bench behind Herrera. Adrian Del Castillo is the only other catcher on the 40-man roster. He’s a far better hitter than either Herrera or Garcia but isn’t regarded as a great defender. Del Castillo won’t be an option in the immediate future regardless, as he landed on the Triple-A injured list today with what is expected to be a minor back injury. Moreno will be the clear starting catcher once he’s healthy, but his injury could lead the Snakes to pursue a veteran #2 who can provide more punch than Herrera offers.
Henry, 27, is a former second-round pick who has a 5.07 ERA over 37 career appearances. He has an ERA above 8.00 over 11 starts in Triple-A Reno this year. This is his final minor league option season and he seems unlikely to stick on the 40-man roster throughout the offseason. His elbow injury occurred in Triple-A, so he’s on the minor league injured list. He’ll continue to count against the 40-man for now. The D-Backs may place him on the MLB 60-day IL or simply decide to release him (which would save them a bit of money relative to putting him on the MLB injured list) once they need another roster spot.
Dbacks “magic year” when everything was lined up and they pushed their payroll to the breaking point has not gone well. Just goes to show, whether it’s “on schedule” or early, you gotta go for it when the chance comes if you’re a mid to low revenue team.
The Dbacks have tried as hard as any team in baseball to build a contender these last few years.
It just goes to show, that even the best of intentions and plans go awry without a little good luck on the health front.
NOOOOOOOOOOOO
Didn’t I read this same article about an hour or two ago? No updates in this one over the last one.
You’ve got this!
In other news from the day, the Arizona Diamondbacks reported that GM Mike Hazen had Tommy John surgery and is out through the 2026 season.
Terrible when the GM is the emergency pitcher and he has Tommy John too.
Don’t trade for relievers with term left on their contracts. You open yourself up to this happening.
I can see them as one of the teams taking a flyer on Erik Swanson to help out with that bullpen.
As an organization, you can’t be afraid to go for it. They did and failed, unfortunately. You’re either the Rays who never take a risk or the Dbacks who do and lost the bet. I’d prefer to go for it.
