Grip Strgth (LH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Grip Strgth (RH)
Grip strength is a measure of a players bat control and ability to transfer power and speed during impact, measured in pounds of force generated; collected with elbow bent at 90 degrees.
Uncommitted. 6-foot, 170-pound frame, athletic, high-waisted build, plenty more room to add strength in the coming years. Started at shortstop and hit in the eight-hole for the Patriots. High-level defender on the dirt, captain of the infield with clear feel for the position and IQ, vocal leader. Rangy actions with fluid feet, moves well to both sides of his glove, soft and confident hands, crisp transfers with a clean arm and quick release. Upside right-handed swing with a loose operation. One to follow closely in the coming years.
Positional Profile: SS/RHP
Body: 5-11, 160-pounds. Proportionate, athletic build.
Delivery: Up-tempo mover, hybrid delivery, medium leg lift into drop-and drive lower half.
Arm Action: RH. Full arm action, clean 3/4 slot.
FB: T84, 81-84 mph. Clean out of the hand, slight arm-side run. T1821, 1756 average rpm.
SL: 68-69 mph. Sweeper shape, heavy horizontal movement. T1934, 1830 average rpm.
CH: 71-74 mph. Late arm-side run. T1741, 1460 average rpm.
Hit: RHH. Narrow, upright setup, minimal load and short stride. Loose, easy hands, fluid, sits into lower half. 65.1 mph bat speed with 10g of rotational acceleration.
Power: 88 mph max exit velocity (83 avg.); 257-foot max batted distance.
Arm: RH. INF - 82 mph. Longer arm circle, high 3/4 slot.
Defense: Two hand gather into body, shuffle through to target, feel for the position, clean double play turn, athletic.
Athletic Testing: 7.60 runner in the 60-yard dash; 22.40-inch max vertical jump.
Vizual Edge: 65.54 Edge Score.
RHP Blake MacMillin (Stevenson, 2028) is a young right-hander to follow moving forward. He’s an athletic mover with a hybrid, up-tempo delivery, working into a medium leg-lift and drop/drive lower-half. The arm action is clean and full out of the glove, playing from a ¾ slot. The fastball jumped out of the hand in the 81-84 mph range with running action arm-side, playing around the zone. His slider showed shorter 10/4 shape with developing spin, 68-69 mph - while the changeup played 71-74 mph with heavy arm-side run and some feel around the zone.
