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

VA/DC Last Chance Open
Kaczmarek is 6-4 with an athletic frame that has some strength present and some projection left to it. He hits from the right side from a slightly open balanced athletic stance, strides on line, smooth load back. Hips rotate completely and he maintains some lower half balance. Hands stay inside, quick to the ball, uphill swing path, some strength at contact with extension through the ball, showed a pull approach with the ability to use the whole field, natural loft in his swing, some power present to all fields, exit velocity was 92. In the outfield, gets body behind the ball and fields through it with soft hands, clean exchange, throws from a high three-quarters arm slot, long loose arm action, position velocity was 85. Ran a 6.91 60 yard dash. On the mound, he throws from a three-quarters arm slot, short free quick arm action and higher effort to his delivery. Drop and drive delivery, shoulders are slightly closed and level, lands on line with an athletic finish. Fastball was 78-83, with downward plane and a bit of late armside run. Curveball was 68-71 with good armspeed and gradual 11/5 break to it. Change-up was 75-77 with good armspeed and hard armside run.
TPG III
Kaczmarek is 6-4 with a lankier athletic frame that has long levers and some projection left to it. He throws from a higher three-quarters arm slot, short loose arm action that is quick and some effort to his delivery. Shoulders are level and closed, lands closed with a fall off finish. Fastball was 77-83, touching 84, with some downward plane and some late run to it that got some depth. Curveball had good armspeed and was 67-68 with gradual 11/5 break to it and some shape that has a chance to tighten into a good pitch. Change-up had some armspeed and was 68-72 with some sink.
Preseason All-State II
Kackzmerak is 6-4 with a lankier athletic frame that has plenty of projection left to it. He throws from a high three-quarters arm slot, very short loose arm action that is quick, some effort to his delivery. Shoulders are level and closed, lands closed with a fall off finish. Fastball was 82-84, with some run to armside. Curveball had good armspeed and sharp 11/5 break at 70-72. Change-up had good armspeed and was 70-72 with some late run.
Long projectable frame with long limbs at 6-foot-4, 180-pounds. At the plate started with a square upright stance, strides closed, and hands load back with a slight bat wrap. Level path through the zone with some bat speed and strength in the swing. Displayed some aggression in the swing with power potential, especially to the pull side. Exit velocity of 86 mph. Defensively showed best in the outfield. Solid glove presentation, fields out front, eyes follow to catch. Full arm circle from a three-quarter arm slot for a positional best 88 mph with plenty of carry. Had an infield velocity of 84 mph. Home-1st time was 4.07. Long term, Kaczmarek’s best fit may be on the mound. Worked primarily out of the stretch. Consistent leg lift, sinks in backside, and drives down the mound landing closed. Full arm circle and works from a three-quarter arm slot. Easy 81-83 mph on the fastball with what appeared to be plenty more in the tank. Offspeed stuff is still developing, but shows a lot of promise on all three secondary pitches with present armspeed. Curveball had tight late 12/6 shape at 72-75 mph. Changeup was 76-79. Slider sat 73-74 mph. This is definitely an arm to watch grow as we go into the spring season.
