Corbin Burnes will undergo Tommy John surgery, Arizona Diamondbacks manager Torey Lovullo revealed Friday.

Burnes injured his right (throwing) elbow Sunday against the Washington Nationals and left during the fifth inning. He was placed on the injured list Tuesday with what was termed elbow inflammation.

Lovullo told reporters that Burnes’ surgery will take place next week.

“It was a lot of information, a lot of fast-moving information, a lot of people weighed in on this, and Corbin felt like this was the best decision for him to continue pushing forward,” Lovullo said, adding that there was no timetable for his recovery.

The Diamondbacks signed Burnes, 30, to a six-year, $210 million contract in free agency in December.

Burnes won the 2021 National League Cy Young Award while with the Milwaukee Brewers and finished fifth in American League Cy Young balloting last year in his lone season with the Baltimore Orioles.

The four-time All-Star finishes his first season in Phoenix 3-2 with a 2.66 ERA and 63 strikeouts in 11 starts.

Burnes is 63-38 with a 3.15 ERA and 1,114 strikeouts in 210 appearances (149 starts) in eight seasons with the Milwaukee Brewers (2018-23), Baltimore Orioles (2024) and Diamondbacks (2025).
