Top 2017 Defensive Arm Velocities

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.

A 6-foot-0, 175-pound right hand hitting OF/RHP who ran a 7.10 60.  At the plate he has a wide balanced stance with a short stride on the pitch.  He shows strong drive with his lower half and good extension out front.  Swing path is flat through the zone with good pull power.  Exit velocity was 92 MPH off the tee.  In the field he glides to the ball and shows max effort on his throws.  He delivers from an over the top arm slot at 86 MPH with accuracy to the bag.  On the mound he is balanced and smooth in his wind up.  He lands in-line with the plate and stays square on his follow through.  Fastball was 84 MPH with good command of both sides of the plate. He also showcased a 67-69 MPH curve with 11/5 break and a 72-73 change.  

Mason Speirs, Broomfield, C/INF
Arm Velocity: 86
5-foot-11, 202 pounds. Bats and throws right.  Currently one of the top uncommitted catchers in the state. Hands are loose in load and swing path is short to the ball with good bat speed. Goes gap to gap. Generated a 90 mph exit velo off a tee, and there is more room to improve if lower half gets a little more involved. Was the best defensive catcher at event. Made framing and blocking look easy, and was 1.83 off pitcher in between innings down to 2nd. 82 mph down to 2nd. Back picked a runner off 1st from knees during games. Solid catching prospect.  We saw Speirs at 3rd base during this event, he showed soft hands and quick feet.  He throws from a high ¾ arm slot with a quick release.  Arm velocity was 86 MPH across the diamond.

Eric Cox, Cherokee Trial, OF/RHP
Arm Velocity: 83
A 5-foot-10, 205-pound right hand hitting OF/RHP who ran a 6.90 60.  Starts open at the plate with a slight leg kick and long stride to get even.  Aggressive weight transfer and quick hands with a slightly uphill swing path created balls with good carry to the gaps.  He registered a 95 MPH exit velocity off a tee.  In the field he uses his speed to cut balls down.  He is max effort on his release and delivers an 83 MPH ball with accuracy.  On the mound he gets to balance and rocks back before landing in-line with the plate.  He delivers from a high ¾ arm slot and featured an 81 MPH fastball.  He finished with a 68-69 MPH curve with 11/5 break and a 74-75 MPH change.
