Spencer Schwellenbach, Hurston Waldrep To Undergo Elbow Surgery

Braves righty Spencer Schwellenbach underwent surgery to remove loose bodies from his right elbow today, manager Walt Weiss told the team’s beat this morning (link Mark Bowman of MLB.com). Fellow righty Hurston Waldrep, who was also diagnosed with loose bodies in his elbow this spring, will undergo a similar operation on Monday. Weiss and the Braves have not put a formal timetable for a return on either young righty. Schwellenbach is already on the 60-day injured list, and Waldrep will surely join him there whenever Atlanta needs to open another 40-man spot.

Neither revelation is especially surprising, but both are notable all the same. Schwellenbach suggested that an arthroscopic procedure was likely last week when he was placed on the 60-day injured list. He said at the time that he was unsure what the recovery time period for such a procedure would be, and the team provided no further details today. Beyond the fact that he’ll miss at least the first 57 days of the seasons — the Opening Day IL placement can be backdated by three days — Schwellenbach can just be considered to be out indefinitely.

It’ll be the same story for Waldrep, who was cleared of structural damage to his ulnar collateral ligament in a recent MRI but found to have loose bodies in his elbow as well. As with Schwellenbach, Waldrep implied that surgery was likely when telling reporters that the loose bodies in his elbow “probably need to be dealt with.”

Heading into camp, Schwellenbach and Waldrep looked like locks for rotation spots. Schwellenbach missed time last summer with an elbow fracture but had completed five to six bullpen sessions, by his own estimate, before feeling pain at the end of a session a bit more than two weeks ago. The 2021 second-rounder has been brilliant since making his MLB debut in 2024, pitching to a combined 3.23 ERA with a 25.2% strikeout rate and 4.4% walk rate in his first 234 1/3 MLB innings.

Waldrep just debuted last season and wasn’t quite as cemented on the starting staff, but he was the heavy favorite for Atlanta’s fifth starter gig. In 56 1/3 innings last year (nine starts, one relief appearance), the 2023 first-rounder posted a tidy 2.88 ERA with a 24% strikeout rate and 9.6% walk rate. He also posted a 4.42 ERA in 19 Triple-A starts, shaking off a rocky stretch early in the season with a pristine 1.99 ERA over his final seven minor league starts before being promoted.

With Schwellenbach and Waldrep sidelined indefinitely, Atlanta’s rotation includes Chris Sale, Spencer Strider, Reynaldo Lopez and Grant Holmes. It’s a talented quartet, but Sale has a lengthy injury history and has only had one fully healthy season since the 2017 season wrapped. He won the NL Cy Young Award in that lone (mostly) healthy year, but there’s considerable injury risk for the lefty, who’ll turn 37 next month.

Strider, meanwhile, posted pedestrian results and rate stats during last year’s return from UCL surgery. Lopez made only one start in 2025 due to arthroscopic shoulder surgery. Holmes suffered a UCL tear last summer but has been rehabbing it without surgery and is said to be full-go this spring.

All four of the Braves’ set-in-stone rotation members come with some combination of injury, performance and/or workload concern. Be that as it may, the organization continues to downplay the possibility of bringing in further help from outside the organization. Gabe Burns of the Atlanta Journal-Constitution recently wrote that the Braves’ previously reported interest in Chris Bassitt (who’s since signed in Baltimore) and Lucas Giolito (still unsigned) was overstated. There’s been speculation that perhaps president of baseball operations Alex Anthopoulos is simply at or close to the budgetary limit set by ownership, though the team obviously wouldn’t publicly disclose that even if it were true.

In-house options to round out the staff include Bryce Elder, Joey Wentz, José Suarez, prospect Didier Fuentes (still just 20 years old) and non-roster veterans Martín Pérez, Carlos Carrasco and Elieser Hernández.
