Former Vanderbilt Commodores baseball star Kumar Rocker, draft-eligible again, had September shoulder surgery, sources say

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 New York Mets after the team balked at the condition of his 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 Valley Cats of the independent 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.

Rocker's medical information, including the procedure performed by Dr. Neal ElAttrache, was distributed to teams in recent days leading up to the July 17 draft, in which he's expected to again go in the first round. In a draft short on pitching, Rocker's combination of pedigree and the stuff he showed in Tri-City could compel teams to consider him far earlier than they were in recent months.

Following a breakout performance as a freshman during which he was named Most Outstanding Player during Vanderbilt's run to a College World Series title, Rocker spent the next two years as the most recognizable name in college baseball. His final season with Vanderbilt in 2021 was characteristically excellent, with 179 strikeouts in 122 innings and a 2.73 ERA, but his fluctuating velocity concerned teams at the top of the first round.

The Mets were initially elated he dropped to them and planned to offer a $6 million signing bonus — $1.26 million more than the slot value of the 10th pick.
