Overview

• Burnes sustained a tear in the ulnar collateral ligament during his June 1 start and will have Tommy John surgery, ruling him out for the remainder of 2025.
• The procedure typically requires 12 to 18 months of rehabilitation, potentially delaying his return until the 2027 season.
• Before the injury, Burnes was 3-2 with a 2.66 ERA across 11 starts in his first season with Arizona.
• He signed a six-year, $210 million deal last winter that includes an opt-out clause after the 2026 campaign.
• Right-hander Ryne Nelson will step into Burnes’ rotation spot as the Diamondbacks seek to climb back into the NL West race.
