2015 Top 40 Season in Review

Physical Description: Athletic, projectable frame. On the skinny side at present, with room to fill out. Low-mileage arm.  

Mechanics: Arm-heavy delivery. Doesn’t utilize his lower half much and has some effort, especially when viewed from the side. Three-quarters arm slot. Almost short-arms the ball and has a slight stab.  

Fastball: 93-95 mph. Topped out at 98 in college. Potential plus-to-better offering. Pitch shows late life and plus sink. Potential to miss bats at the highest level. Loose arm and elite arm strength that helps him generate easy velocity even though he doesn’t use his lower half to great effect. Below-average command and control.  

Curveball: 71-74 mph. Plus potential. Loose and rolls to the plate at lower velocities. Shows sharp break and depth through the zone when he snaps it off.  

Changeup: 82-83 mph. Average potential. Throws with similar arm speed to his fastball. Shows drop and fade in on right-handed hitters. The pitch looked much improved in 2014 fall instructs from where it reportedly was during his junior-college season.  

Slider: 84 mph. Short 10-4 break. Thrown sparingly as a pro thus far.  

Career Notes: Redshirted his freshman season at Duke as an outfielder, then transferred to Seminole State to become a pitcher. Brother Jarred is a starting pitcher for the Miami Marlins.  

Summation: Has the arsenal and athleticism to profile as a number three starter, but has a lot of development to go. Delivery isn’t something you’d teach, but it works for him mainly due to elite arm speed. Potential for three average-to-better offerings, including plus-plus velocity. Improving command and control will be key for his development, as will refining his secondary pitches. Stuff will play out of the bullpen if need be.
