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.
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

Janczak is a high wasted, long and projectable 6-foot-2, 180 pound prospect. Janczak works the ball downhill with a long, loose and whippy arm from a high three-quarter slot. His fastball topped at 84 mph with notable spin rate (2200+) showing feel for the zone and ride and carry to the pitch. He pairs the fastball with an 11/5 breaking ball with notable depth at the plate making it a potential out pitch weapon for both handed hitters. The change up has late sink at the plate giving him three offerings to get hitters out. Janczak is an upside prospect in the state.
Positional Profile: RHP/OF
Body: 6-2, 180-pounds. Long lanky frame, high waisted.
Delivery: Balanced delivery, short medium lift, lands square and works online.
Arm Action: RH. Loose arm with arm speed, high 3/4 slot.
FB: T84, 83-84 mph. Typical arm side action, average feel. T2221, 2158 average rpm.
CB: 71-73 mph. Flashed downer action, mostly 11/5 shape. T2191, 2108 average rpm.
CH: 78-79 mph. Plays with sink to arm side. T1723, 1652 average rpm.
CUT: 78-81 mph. Shows slight cut action.
Extra long levered wiry frame with projection, quick arm from high 3/4 slot, indicating there may be more velocity in future, ability to time up mechanics. Throughout his outing Janczak produced fastballs at 75-80 mph all around the zone and showed feel/shape for slurvy-type breaking ball that registered at 67-70 mph.
