Gann’s height, or lack thereof, is the first thing you notice when he toes the rubber. He’s listed at 6’0”, which appears generous, and he doesn’t have an ideal physique, which makes what happens as soon as the batters dig in remarkable. Gann utilizes every single inch he has in his delivery, and he generates surprising plane with his fastball. It runs 91-to-93 mph and gets heavy down in the zone, making it difficult to hit anything flush off of him. His curveball runs in the 76-to-79 mph velocity band and can flash plus with depth and deception.
Gann uses both offerings to attack left-handed and right-handed hitters alike, utilizing his heavy fastball down in the zone and effectively elevating from time to time, as well. Gann will occasionally mix in a changeup, but it’s behind his other two offerings at present. There’s effort in the delivery with some crossfire, which can negatively impact his consistency and command, so remaining a starter may be a tall task for Gann. Out of the ‘pen, he profiles as a potential seventh-inning arm who pitches with good stuff and courage. – Mauricio Rubio
