Scouting Report

2025

Scouting grades: Fastball: 50 | Slider: 60 | Changeup: 50 | Control: 45 | Overall: 40

Petit was a two-time All-Big South First Team selection at Charleston Southern, including as a junior starter in 2021 when he posted a 2.79 ERA in 84 frames. The Tigers selected him in the 14th round that summer and signed him for $125,000, making him the first Charleston Southern player drafted in three years. Petit immediately moved into a relief role in the pros and has remained there since. He pitched well in Double-A in 2024 but was left unprotected and unpicked in that December's Rule 5 Draft. After a strong 2025 campaign that saw him reach Triple-A, Petit was once again left unprotected, but this time the Rockies made him the top pick of the Rule 5.

Standing at 6-foot-8, Petit is a tremendous presence on the mound. He doesn’t get big extension out of that frame, instead using his height to create a steep downward plane leading to solid groundball rates. There is some velocity here, touching 98 mph while sitting 94-96, and he's worked to generate a bit more heat. Petit’s 83-85 mph gyro slider is much better at generating swing-and-miss and chase low in the zone with strong depth, and the Rockies think it's the kind of breaking ball that should play in Coors Field. He can tunnel his 86-89 mph changeup well enough off the fastball with just enough velocity separation for it to be effective.

Petit has shown the ability to get righties and lefties out at the upper levels, and he was able to get his walk rate back down in 2025 to 3.0 per nine after seeing it creep up in 2024 (4.1 BB/9). He'll get his chance to stick with the Rockies, who see him as a potential bulk reliever.
