10/21/23

Blahnik’s fastball sat in the low-80s throughout his ‘pen, topping out at 83.5 mph. His fastball played with occasional cutting and sinking action and flashed the ability to work around the zone. Blahnik also showed the ability to throw a low-80s sinker that he was able to consistently throw for strikes with slight sinking action. Blahnik threw two offspeed pitches that project to be potential weapons; a heavy fading changeup that averaged 15.1” of run and a sweeping slider that played with 16” of sweep on average.

3/18/23

Blahnik is an uncommitted junior that left Saturday’s event with an arrow up. Listed at an athletic 6-foot-1, 180-pounds, Blahnik works with an up-tempo delivery and loose ¾ arm to produce sinkers in the 82-84 mph range with dive through the zone - also featuring a four-seam fastball with finish through the zone. His slider looks to be a potential out-pitch, playing with sharp 2/8 shape and sweep. His final offering was a fading changeup, thrown with fastball intent at 78-79 mph.

8/22/22

Standing at 6-foot-1, 180-pounds, the southpaw has room to add strength to his lean and projectable frame. On the mound, Blahnik moves with a high leg-kick into a drop/drive lower-half, remaining in-line with the plate throughout his stride. His arm plays with a long/loose arm swing out of the glove into a high ¾ slot. The left-hander’s fastball cruised in the 80-82 mph range, topping out at 83 mph (T2255 rpm). He went to two different breaking balls to pair off his fastball; the first being a sharp 1/7 curveball with late break at 68-69 mph (T2426 rpm) and the second being a sharp 2/8 slider (T2428 rpm).
