Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Tall and strong build, standing at 6-foot-4, 198-pounds. The southpaw begins his windup from the third base side of the rubber. Starts with his hands up high and never dips below his midsection. Big leg kick leads right into his hip hinge, is on time. Drops the back shoulder and comes at you from a lower slot. Maintains his stride direction with even shoulders down the mound. FB sat in the 81-82 MPH range. Dropped the arm a bit on the SL, inducing more lateral break at 67-70 MPH. CH plays well off the FB, was 71-72 MPH.
