Scouting Report
Frame: Athletic, explosive, compact, 5-foot-11, 175 pound frame. Toolset/Profile: Biernacki has the classes' best present toolset. He burned a 6.61 60-yard dash, already a real tool, and his 1.58 10-yard split shows the acceleration he brings between the lines. There is real thunder in the barrel already with explosive bat speed (event-best max bat speed, 81.9 mph) and exits already eclipsing 98 mph. The arm is a present tool, reaching 92 mph, and he also has some upside as a RHP with a mid-80s fastball and high-spin breaking ball. He profiles best as a R/R CF and has speed/power upside offensively. Actions: Offensive - Sets up in a taller stance with open front foot. He starts with some tension in the back hip and the barrel laid perpendicular to the shoulder plane. There is a small leg-lift gather before an aggressive-but-controlled positive move and the upper body has a small pull-back load. I love how the barrel turns off the shoulder. There is exceptional launch quickness and the bat is on-plane throughout. Showed the ability to use the entire field with tons of back-side feel. Defense - Aggressive athlete with sure hands. Run time suggests elite upside in CF. The arm is ultra-quick. Summation: Biernacki is a dynamic player with real tools and showed a more-physical look at this event compared to last summer. The explosiveness shows up in all-parts of his game, and he also turned in a 28.5" vertical leap, 2nd-best at the event. I couldn't be more bullish on the offensive profile with a real chance to hit and speed that will play the hit tool even higher. The shorter R/R profile will follow him, but the tools play like he is 6-foot-4, and the arm and quickness could help mitigate that if he can show elite defensive skills in CF. Shooter Hunt often talks about "aggressive athletes with apptitude" and Biernacki fits that mold to a T.
