07/20/2020 - All-In Membership - Rosemont (Chicago), IL Joshua is an athletic/projectable LHP who has upside on the mound. This lefty toes the rubber and works to a controlled balance point with smooth separation. Delivery is a little deceptive giving hitters an uncomfortable look. He works quickly and attacks the zone. FB ranges from 68-70 mph while showing slight arm-side run. Breaking ball has 1/7 shape while changeup has slight run. Working to stride more square to his target will allow for more drive from his lower 1/2, aiding in increasing his velocity. As a hitter, Joshua shows an athletic setup with centered balance. He tracks pitches into the zone, gets loaded and swings against a firm front side. He squares the ball up and has some pop to his pull-side (exit velocity = 82 mph). Delvalle is a couple adjustments away from unlocking his potential on the mound.
