Top Prospects: LHP Analysis

Les Lukach
State Scouting Director

The inaugural Top Prospects Showcase took place on Wednesday, August 1st at O'Malley Field, home of the Harvard Westlake Wolverines. The event attracted over 100 players in the 2019 class many of whom are in our Class of 2019 Top 100 rankings. With over 20 colleges and seven (7) MLB clubs in attendance, the participants were put through a pro-style workout to showcase their abilities.

As part of our continuing coverage of the event we will continue to break down all the data, roll out stats, content, and videos from the event. In this edition we present the left-handed pitchers analysis from the Top Prospects Showcase.
