CF Mason Biernacki, 2028, Penn: I’ve now seen ~7 at-bats from Biernacki this spring and he continues to further cement himself as one of the top prospects in the class. Athletic frame at 6-foot, 180-pounds and still some room to grow into it. Hits out of a balanced stance before a slight wrapping load. Adjustable stride; will hover at times while also using a toe tap to maintain balance. Turns an on-plane barrel that works uphill out-front. Gets off advanced bat speed for the age. I saw two hits across my looks, one firm, head-high liner through the middle, and another out-front single where he showed the ability to use his hands and manipulate the barrel. He consistently turned in plus run times (4.19 average) and was quickest on a jail-break (4.02). He uses his speed on the bases as well as just about any prospect that I’ve seen at this age. The instincts are outstanding and he looks to take the extra base. An elite defensive CF with plus arm strength - I think Biernacki may be the best present day performer amongst position players in this class and is likely to be recruited heavily by schools across the country come August.

Continuing to show the dynamic all-around abilities that our staff has come to expect, Biernacki was easily one of the top offensive prospects at this event. Uber-athletic and explosive at 6-foot, 180-pounds, Biernacki turned the barrel tight for a familiar look from the right-side with as much or more barrel feel than any in attendance. Peaked at 102.4 and averaging 95 throughout, the combination of launch quickness and length through the zone calls from premier hit/power projections that are elevated by a 6.71 run time. For good measure, Biernacki concluded his performance with an event-best 93 mph OF arm.

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.
