D-Backs’ Tyler Locklear To Undergo Elbow, Shoulder Surgeries

Diamondbacks first baseman Tyler Locklear will undergo surgery on both his left elbow and shoulder later this month, reports Nick Piecoro of The Arizona Republic. The rookie suffered a ligament tear in his elbow and a labrum injury in his shoulder.

The procedures make it likely that Locklear will open the 2026 season on the injured list. John Gambadoro of 98.7 FM reports that the team is hopeful he’ll be ready for game action by the end of Spring Training. That wouldn’t give him much time to get used to facing MLB pitching, and the Snakes would probably have him open the season on the IL so he could go on a minor league rehab stint. It’s possible he’s back sometime in April, though there’s obviously a wide range of outcomes for a player coming off simultaneous significant surgeries.

Both injuries occurred on the same play. Locklear, a right-handed thrower, was playing first base against Boston on September 7. Connor Wong hit a grounder to third that Jordan Lawlar threw high and wide to first base. Locklear stretched his left arm up and away from his body while trying to keep his foot on the bag. Wong collided with Locklear’s arm as he ran through the base. The play resulted in a two-run error to give Boston a 5-4 lead they’d never relinquish. Locklear was knocked out for the season.

A former second-round pick by the Mariners, Locklear was the key piece of Arizona’s return in the Eugenio Suárez trade. Seattle hadn’t given him much of a big league opportunity. The D-Backs had traded Josh Naylor to the M’s a week earlier, so they plugged Locklear in as their primary first baseman. He had a tough time in his first regular look at big league pitching. The Virginia Commonwealth product batted .175/.267/.262 while striking out 37% of the time across 116 plate appearances.

While it wasn’t an impressive MLB look, Locklear has little left to prove against minor league pitching. He’d turned in a .316/.401/.542 slash with 19 homers and 18 stolen bases over 98 Triple-A contests in the Seattle system. That’s fantastic production even in the Pacific Coast League.

On Wednesday, Gambadoro downplayed the likelihood that the Diamondbacks would make a significant offseason move at first base. It’s unclear if the extent of Locklear’s injuries will change the calculus. The Snakes presumably still want to give him the opportunity to get more comfortable against big league pitching. Yet he’s likely to at least begin the season on the injured list and it’s not hard to imagine elbow and shoulder injuries impacting his swing even when he’s able to get back on the field.

Pavin Smith is the presumptive starter for the time being. He’s coming off a solid .258/.362/.434 showing overall, though the positives were mostly concentrated in a huge first month. Smith hit .222/.311/.351 while striking out a third of the time after the start of May. He missed all of September with a quad strain. The Snakes also don’t have a true designated hitter, leaving open the possibility of bringing in a veteran bat to fill one of those positions while letting Locklear, Smith and Adrian Del Castillo compete for playing time at the other.

Pete Alonso and Naylor top the free agent class at the position. That kind of splash is unlikely given Arizona’s greater need for additions in both the rotation and bullpen. A reunion with Paul Goldschmidt or a one-year deal for Rhys Hoskins or Dominic Smith could be on the table. Nathaniel Lowe is unlikely to be tendered a contract by the Red Sox, while Ryan Mountcastle or Spencer Steer may find themselves in trade rumors.
