1B/OF/LHP Greyson Alesia (Hinsdale Central, 2027) put together one of the better all-around showings at the event. Presenting a projectable frame at a trim, 6-foot-3, 160-pounds, the left/left prospect was among the event leaders in the 60, posting a 6.95. He showed a loose and athletic swing from the left side that reached a max EV of 91 mph (avg. 86.1 mph), while hitting his furthest ball 339 feet. Alesia also showed natural actions and feel for the first base position during defense; picking balls with ease and showing flexibility around the bag. His fastball showed natural heavy running action up to 76 mph, pairing with a slider and a changeup.
+ OF/1B Greyson Alesia (Hinsdale Central, 2027) gave one of the stronger defensive looks on the day, showing versatility with quality rounds both in the outfield and at first base. In the outfield, he has long/easy strides that allow him to cover ground easily, pairing with a loose/easy arm that was up to 83 mph from a crow hop. At first base, he showed natural, confident actions around the bag with some flexibility in his hips/lower-half, pairing with soft hands and fluid footwork. Also a left-handed hitter, the 6-foot-1, 153-pound prospect has more power to come in his balanced, projectable operation at the plate.
Positional Profile: OF/1B
Body: 6-2, 150 pounds. Athletic, high waisted frame with room to add size.
Hit: LHH. Balanced setup, small leg load, rhythmic hands pre-pitch. Direct path with some whip, utilizes lower half, drives ball in air to pull side. 65.8 mph bat speed with 16g of rotational acceleration.
Power: 88 mph max exit velocity (72.2 avg.); 273-foot max batted distance.
Arm: LH. INF - 77 mph. OF - 83 mph. Quick, compact path, low 3/4 slot.
Defense: Athletic movements, soft hands, smooth gather.
Athletic Testing: 7.37 runner in the 60-yard dash; 27.60-inch max vertical jump.
Vizual Edge: 85.47 Edge Score.
