Primary Pitchers

Dylan Antonini, Phoenixville Area HS, RHP, 2023
5-foot-8, 140-pound righty sat 77-79 from a high 3/4 arm slot. Displayed a balanced, repeatable delivery while routinely getting downhill. Curveball showed 11/5 rotation at 66-67 with late, slider type action. Cutter is a solid pitch with gradual movement at 74-76. Definite follow in this class that should continue to see strides through physical maturity and strength gains.

Eric Gustofson, Easton Area HS, LHP, 2020
5-foot-11, 185-pound senior sat 83-85 from a high 3/4 arm with a strong lower half drive. Showed solid command of his fastball with heavy arm-side run. Curveball at 71-73 displayed 1/7 rotation. An above average cutter at 78-79 and a changeup at 76-78 with similar arm-side run completed an advanced four pitch arsenal. Gustofson announced his commitment to West Chester University the day following the event.

Brandon Holzinger, Liberty HS, LHP, 2021
6-foot-6, 185-pound lefty sat 77-78 from a high 3/4 arm slot. A high effort delivery includes a high knee stack and a hook in back during takeaway. Curveball showed late depth with 1/7 rotation at 60-64. Changeup at 67-72 was thrown at near fastball arm speed. Athleticism and balance along with a plus frame makes Holzinger a definite follow among uncommitted left-handers in this class.

Dante Mack, Easton Area HS, RHP, 2021
6-foot-1, 174-pound righty sat 75-76 out of a high 3/4 arm slot. Delivery is deliberate and balanced with a high-knee stack and a long takeaway. Repeats delivery well and commands three pitches. Curveball showed 11/5 rotation at 66-67. Displayed solid arm speed on changeup at 69-70.

Gavin Mikulski, North Penn HS, LHP, 2021
6-foot-2, 170-pound lefty sat 78-82 from a high 3/4 arm slot while creating some downhill angle on his fastball. Showcased a deliberate tempo with some hip coil to his stack. Displayed above average feel and depth on his curveball at 64-68 with 1/7 rotation. Also showed a feel for a cutter at 76-77. Athletic frame has room for added strength and velocity gains are likely moving forward.

Carson Renner, Brandywine Heights HS, RHP/SS, 2023
5-foot-11, 155-pound freshman sat 77-79, topping at 80 mph out of a 3/4 arm slot with hip coil to his delivery. Curveball at 62-65 showed some depth with 11/5 rotation. Changup at 69-71 was thrown at near fastball arm speed. Right-handed hitter starts from a square stance and initiates his swing from a high elbow load with a lift-and-replace stride. Lower half glide in stride phase leads to some length in swing. Displayed a feel for the baseball and a middle of the field approach. Registered a bat exit velocity of 84 mph and ran a 7.44 60-yard dash. Showcased developing defensive skills with active feet and accurate 77 mph arm strength across the diamond. Freshman showed advancement across the board since we last saw him eight months ago and will be a prospect to follow in this class.

Aaron Renninger, Carlisle Area HS, LHP, 2021
6-foot, 156-pound lefty sat 77-79 from an over the top arm slot. Repeats delivery well and creates downhill angles on his fastball. Curveball at 67-71 displayed 1/7 rotation with tight, late bite at its best. Changeup is thrown at near fastball arm speed with arm-side run at times and cut at others.  

Conner Rex, Notre Dame Green Pond HS, LHP, 2022
5-foot-9, 175-pound lefty sat 80-82 from a high 3/4 arm slot with a compact, repeatable delivery. Fastball showed some arm-side run and changeup at 71-73 showed similar fade with some late sink. Curveball lacks depth with 1/7 rotation at 68-69.

Steven Rinda, Boyertown Area HS, RHP, 2021
6-foot-1, 150-pound righty sat 79-81 out of a 3/4 arm slot. Arm action is long and easy. Delivery is balanced and repeatable. Curveball sat 68-70 with 11/5 rotation that showed two-plane depth at times. Changeup at 71-73 is an advanced pitch with arm-side run and sink. Athletic frame has room for added strength and velocity spikes are likely moving forward.

Dylan Robinson, Plymouth Whitemarsh HS, RHP, 2023
5-foot-8, 149-pound freshman sat 69-71 from a high 3/4 arm slot. Gets downhill routinely out of a balanced, repeatable delivery. Curveball at 61-66 showed 11/5 rotation. Slider at 60-63 displayed a shorter, more horizontal break.

The right-handed hitter starts from a square stance and initiates his swing from a high elbow load with a lift-and-replace stride. Some wrap leads to length in the swing.
