2026 Projections
2026 Fantasy Outlook
Petit, a 6-foot-8 righty from Detroit's farm system, split the 2025 season between Double-A and Triple-A, working primarily as a reliever. The 26-year-old logged a 2.74 ERA, 1.26 WHIP, 33:10 K:BB and 51 percent groundball rate in 23 innings at Triple-A, and while he was used in relief, Petit has the stuff to start. He throws multiple mid-90s fastballs, with his four-seamer touching 98 mph, along with a nasty slider and a solid changeup. Being selected by the Rockies in the Rule 5 draft hurts his fantasy value though he could find a prominent role in the bullpen. Read Past Outlooks
Signed a one-year contract with the Rockies in March of 2026.
Diagnosed with UCL sprain
The Rockies announced Monday that Petit has been diagnosed with a UCL sprain in his right elbow, Thomas Harding of MLB.com reports.
Analysis
The diagnosis is often a precursor to UCL surgery, but Petit will consult with doctors before making a decision. A Rule 5 pick, Petit could be stashed on the 60-day injured list while he recovers, though the Rockies would still have to follow regular Rule 5 roster guidelines once Petit is off the 60-day IL.
