Rockies Reliever RJ Petit to Miss 2026 Season After Tommy John Surgery

SCOTTSDALE, Ariz. — Colorado Rockies reliever RJ Petit will miss the entire 2026 season after undergoing Tommy John surgery with an internal brace on Friday, according to MLB.com [1]. The surgery was performed by Dr. Keith Meister in Dallas.

Petit’s Background and Recent Performance

The Rockies selected the 6-foot-8 Petit in the first round of the 2025 Rule 5 draft from the Detroit Tigers [2], [3]. Originally drafted by the Tigers in the 14th round of the 2021 MLB Draft, Petit progressed through the minor leagues, reaching Triple-A Toledo before being selected by Colorado.

In the 2025 season, Petit posted a 10-2 record with a 2.44 ERA in 47 appearances (two starts) for the Double-A Erie and Triple-A Toledo [1]. He recorded 79 strikeouts and 22 walks across 66 1/3 innings.

Injury Details and Recovery

Petit suffered the injury on March 4th during a game against Team USA [2], [3]. Prior to the injury, he appeared in three spring training games, pitching three innings and allowing four hits, three runs (on a home run), two walks, and one strikeout [2], [3].

Rule 5 Draft Implications

Due to the Rule 5 draft rules, Petit will be subject to those regulations during the 2027 season upon his reinstatement from the 60-day injured list [2]. This situation will create an open roster spot for the Rockies as they finalize their Opening Day plans.

Career Statistics

Over five minor league seasons, Petit has a career record of 21-15 with a 3.40 ERA and 14 saves in 182 relief appearances and five starts [1].
