Former Vanderbilt star Kumar Rocker underwent shoulder surgery in September, receiving what his agent called "a minor scope" on his right arm, sources familiar with the procedure told ESPN.

Rocker, the 10th overall pick in the 2021 draft, did not sign with the Mets after the team balked at the condition of his pitching arm. Now 22 and again draft-eligible, Rocker has steadily climbed teams' boards over the past month after regularly hitting 98 mph with his fastball in a dominant five-game stint with the Tri-City ValleyCats of the Frontier League.

"We have a very clear understanding, after a minor scope, of Kumar's medically documented health, which has allowed him to perform at the highest levels," said Scott Boras, Rocker's agent.
