CB: 66-68 mph. 12/6, heavy vertical drop, out pitch, keeps it low. T2388, 2319 average rpm.
SL: 68-70 mph. Gradual break, 11/5, horizontal mover. T2240, 2142 average rpm.
CUT: 73-75 mph. 10/4 shape, sharp, works inside half to right-handers.
ATH: 7.44 runner in the 60. 1.72 and 4.04 in the 10 and 30 yard splits. 23.00 max vertical.
+ LHP Austin Adamczewski (St. Thomas More, 2027) measures 5-foot-11, 170-pounds, impressed in his bullpen at last week’s event. The southpaw worked out of a hybrid windup and threw five pitches from a higher ¾ arm slot. The fastball worked at 78-81 mph with 17 in. of avg. IVB, the sinker played in the low 80s for strikes, and the cutter was in the mid 70s. Adamczewski threw a curveball at 66-68 with -14 in. of avg. IVB and 2300+ rpm, and the slider worked at 68-70 mph for strikes and gradual break. The left-hander impressed and showed feel for multiple pitches. A southpaw in the 2027 class to follow.
