Overall, he generated a 20.1 Swinging Strike% with the fastball, which was tops in Division 1 last season.
His second claim to fame is his two-plane slider, which generates 6 in. of gloveside movement at an 85.8 MPH average velocity.
It tunnels well off the heater, with over 18 inches of vertical offset, 15 inches of horizontal offset, and a 10.3 MPH velocity difference from the fastball.
While his changeup is a work in progress, scouts can find solace in the fact that he still gets almost 18 inches of vertical offset from the heater, as well as an 8.8 MPH difference from the fastball.
When hitters are used to his high-90s fastball, it’s no easy task to adjust when Doyle slams the brakes.
For someone who induces as many whiffs as he does, he showed impressive command, as shown by his aforementioned 8.3 BB%.
He’ll likely have fringy to average command as a big-leaguer, hovering in the high-single digits to low-teens in walk rate. This is entirely passable given his arsenal’s ability to make hitters look absolutely foolish.
This past Fall, Doyle made his professional debut with Single-A Palm Beach, making one start before jumping to Double-A Springfield for another, where he’s expected to begin 2026.
