LATEST PG SHOWCASE REPORT
2023 13U/14U Coastal Prospect Showcase  
Corey Mack is a 2028 SS/RHP/C with a 5-11 140 lb. frame from Upper Marlboro, MD who attends Undecided. Medium frame with long levers, wiry strength and some twitch to his actions with a tremendous amount of time to add physicality. Ran the 60 yard dash in 7.14 seconds. Primary position IF, showing a good foundation from a fundamentals standpoint and smooth glove work as he secured the ball well. Plays a bit high in his legs but showed first step quickness and lateral mobility especially to his glove side. Lower slot on throws and changed angles with a peak velocity of 70 mph across the diamond. Reps behind the plate as well, with emerging overall actions here. Getting out of crouch early but made accurate feeds with a pop time best 2.34 seconds. Secondary RHP, utilizing his leverage well and hinging at the waist in transition down the slope. Low-3/4 arm angle with a quick, full arm path in back. Crossbody stride creating deception, just a tough look with some funk to the delivery. FB up to 67 mph fairly true through the zone and developing SL in the low-50s with some sweeping action. RHH with a nice initial setup, using his length well and maximizing leverage. Stays over backside as he works to contact with a bit of torso tilt and creates loft. Repeats well, gets through the ball nicely with his hands and projects both hit and power tool longterm. Outstanding student as well.
