Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
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
Curveball
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Curveball
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Positional Profile: LHP
Body: 6-2/190. Tall, lean build with some room to fill.
Delivery: Stretch from the glove side of the rubber, leg kick up to the waist, long stride, glides down the mound, finishes over front side. Repeatable throughout, consistent mechanics.
Arm Action: LH. Looks to have a more moderate/compact arm swing from a ¾ slot. Stays around the zone and deceptive with offspeed. High spin efficiency.
FB: T78, 77-78. Carry type FB with high end IVB. High efficiency. 29% in-zone.
CB: 63-65. 11/5 shape. Larger rolling break.
CH: 72-73. Slight fade. Kills some IVB off the FB.
Positional Profile: LHP
Physical: 6-1, 170-pounds; Lean, lanky build.
Pitching: Uses a glove side setup working primarily from the stretch. Belt high leg drive with shoulders outside the hips. Has a long stride landing inline with the plate. Moderate arm swing while showing some scap load; high 3/4 slot. Upright with finish. FB: Peak velo of 76 MPH, while sitting 75-76 MPH; arm side run with sink. CB: 61-63 MPH; lands for strikes. SL: 70-73 MPH; short action. CH: 69-72 MPH; sinks. Classic lefty repertoire, feel of CB is above average, creates scissor effect off the FB action, ball hidden on backside.
Bay Area World Series Underclass
Pitching notes: Stretch only. High front leg kick with high glove side having small rock at top of lift. Fluid and full swing to H-3/4; got the front side into the ground well with some crossfire and still more available from backside drive. FB mainly armside with ability to extend plate, go up and have angle that way. FB up got swings. CB overhand 12/6 with late drop; long and fluid pitch. Simple and repeatable actions and FB could tie up hitters, attacing with it. FB 72-76 / CB 59-60
