Previous success stories

A strong performance at the Combine can help prospects boost their stock. At the inaugural event in Cary, N.C., in 2021, Gardner-Webb right-hander Mason Miller threw seven of the eight fastest pitches clocked, averaging 98.2 mph and topping out at 99.1. An Athletics third-round pick that July, he needed just 28 2/3 innings in the Minors before making his big league debut; he's been the A's closer since 2024 and was an All-Star that season.

In 2022 in San Diego, Crowder (Mo.) JC right-hander Jacob Misiorowski was even more electric, averaging 99.8 mph and topping out at 100.7 while unleashing the eight hardest fastballs and also popping a slider at 90.3 mph. Signed for $2.35 million as a Brewers second-rounder, he blossomed into one of the game's top pitching prospects before making a sensational big league debut with Milwaukee on June 12.

In 2023 in Phoenix, prep outfielders Brandon Winokur (Edison HS, Huntington Beach, Calif.) and George Wolkow (Downers Grove, Ill., North HS) put on the most impressive batting-practice displays. Winokur had the highest average exit velocity (108.3 mph) and produced triple-digit EVs on 21 of his 22 swings, including a 437-foot shot, while Wolkow had the best max exit velo (116.2 mph) and smoked five straight pitches 400 feet or more. Both earned above-slot seven-figure bonuses -- Winokur $1.5 million from the Twins as a third-rounder and Wolkow $1 million form the White Sox as a seventh-rounder.

Last year, Colorado prep righty Trey Gregory-Alford jumped 20 spots, from 125 to 105, in our rankings after touching 100 mph at the Combine, then got $1,975,500 as the Angels’ 11th-round pick, setting a record for highest post-fourth round bonus since the bonus pool era began in 2012.

Florida prep infielder Kellon Lindsey was the highest-ranked Draft prospect to participate in on-field workouts last year. He impressed and went to the Dodgers in the first round with pick No. 23, signing for $3.3 million.

Similarly, South Carolina prep outfielder PJ Morlando also benefitted from a great Combine showing last spring, showing off his power in batting practice and then jumping from No. 57 to 43 in our rankings. He signed with the Marlins for $3.4 million as the No. 16 overall pick.

In '24, 224 of the 305 players who participated in the Combine were selected in the MLB Draft (73.4%), including 75 of the first 100 picks. As the Combine continues to grow, the event’s impact is being felt across the game with 55 Combine participants making their Major League debuts as of June 16.
