Top 2019 Defensive Arm Velocities





By Jeff Markle
Assistant State Director

PBR Colorado strives to be the most comprehensive source of player information across the state. The Prep Baseball Report is the No. 1 resource for high school baseball in each state we cover through our variety of events, boots-on-the-ground scouting staff, daily coverage, and multimedia platforms. Our multimedia platforms and events work in tandem, ultimately creating the most powerful source of high school baseball promotion in each state.  While other organizations take a national approach, our goal is to become the authoritative voice on the ground level of each state.

We recently did a series on the top uncommitted pop-times, 60-times, arm velos, and exit velocities. Now we are doing a series on our Top 5 overall numbers for each class.

Top 2019 Defensive Arm Velocities:

Riley Cornelio, Pine Creek, SS/RHP (Texas Christian)
Defensive Arm Velocity: 88
6-Foot-2, 160 pounds. Bats and throws right. Tall balanced stance. Hands start a little lower then last time we saw him. Generates good bat speed by swinging down to the ball, and has slightly uphill path. Good extension through finish. Good rotation on lower half. Gap to gap power. 89 mph exit velo off the tee. Ran a 7.2 60 time. Arm is electric at both short and on the mound. At short glove to hand separation works good. Tall lanky short stop with good range to both glove hand and back hand sides. 88 mph across diamond with accuracy. On mound Cornelio has athletic frame, and arm works great. In two innings struck out 6. Delivery is very simple and explodes to the mound. Very good leg drive. Fastball sat 87-88 and will easily increase with age. Could project to be mid 90's going into college especially since he's only 160 pounds. One of the top prospects in the country in the 2019 class.

Parker Gregory, Pine Creek, OF/RHP
Defensive Arm Velocity: 85
The 5-foot-11, 160 pound RHP has a nice loose arm from high 3/4 arm slot and repeatable delivery with a lot of projection. Fastball touched 85 mph at the Top Prospect Games with a solid 3-pitch mix. Curveball had nice late tilt at 69 mph, and change was same arm speed as fastball with fade at 72 mph. At the plate has a tall narrow stance, short stride, and quick hands through the hitting zone producing a 83 mph exit velo. From the OF threw 85 mph from right. Goes back on the ball well. Ran a 7.4 laser timed 60. Projects as a D-1 pitching prospect.

Tyler Shelley, Ponderosa, SS/RHP
Defensive Arm Velocity: 85
5-foot-6, 140 pounds. Bats left throws right. Shelley is a do-it-all baseball player. At the plate hits from a crouch, toe-tap stride, hands load back with uphill swing. Gets full rotation in lower half. Off the tee produced a 79 mph exit velocity. Shelley has plus arm strength with body size in the outfield had top arm velo of 89 mph, and in the infield was 85 across the diamond from a high 3/4 arm slot. Looks fundamentally solid from both positions. On the mound throws from same arm slot, was inline towards plate, comes through then recoils back after pitch. Fastball lived at 80-82 touching 83 mph. Has high hips so you can see he's going to grow a lot more. Curveball had tight spin with 11/5 shape living at 66-67 mph. Ran a 7.3 laser timed 60. When he grows into body could easily project into upper 80's arm..possibly 90. 

Ethan Frasier, ThunderRidge, 3B/RHP
Defensive Arm Velocity: 84
6-foot-0, 185-pound right hand hitter who ran a 4.6 home to first.  At the plate he hits from a balanced stance with a slight toe tap for timing hands drop at the beginning of the swing creating an uphill swing path exit velocity was 83 MPH.  In the field he shows quick feet and smooth actions through the ball throws from a 3/4 arm slot and showcased an 84 MPH arm.  On the mound he has a balanced leg kick and lands in line with the plate, shows good arm speed on all three pitches showcased a 78 MPH fastball, a 63 MPH curve and a 64 MPH change.   

Kian Manmano, Legend, OF/RHP
