Gavin
Trevillian

RHP Gavin Trevillian (Kingsford, MI, 2025) has an up-tempo delivery that allows him to work quickly down the mound, a dynamic mover. It’s a repeatable delivery with a quick arm and strong finish, generating good velocity despite his short frame. The right-hander worked mostly 83-85, reaching 85.9 mph on the fastball. The fastball has a downhill angle with feel to work in the zone. Likewise, his changeup was around the zone at 72-76 with some depth, a pitch the junior threw with fastball arm speed. The slider is a notch slower at 70-73 mph but with a sharp, 10/4 break. Trevillian has the makings of a strong three-pitch mix.
