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.
One of the day’s top performers, OF/LHP Jace Koth (Jacobs, 2027) gave a strong look on both sides of the ball. The left-handed hitter has all sorts of upside in his swing, displaying athletic hands with whip in the barrel and a line-drive approach, extremely athletic operation with body control and balance through impact. On top of his impressive round of BP, Koth tied an event-best 3.80 in the 30-yard dash. He’s an impressive and fluid athlete in the outfield, attacking the baseball with fluid footwork, fielding the ball in-stride and moving efficiently into a crowhop (T85 mph). He also showed well on the mound, working his fastball up to 80 mph to go along with a curveball he could land for strikes and a changeup.
Positional Profile: OF/LHP
Body: 5-10, 155-pounds. Athletic, sloped shoulders, more fill on its way.

Hit: LHH. Slight back knee bend, early load into a longer stride, lands in-line. Athletic hands with whip in the barrel, possesses slight lift. 65.1 mph bat speed with 10g of rotational acceleration.
Power: 88 mph max exit velocity (79.8 avg.); 310-foot max batted distance.
Arm: LH. OF - 87 mph. Longer action, quick arm, 3/4 slot.
Defense: Attacks the ball, athletic footwork and actions, fields the ball in-stride off front foot, short shuffle step to target.
Athletic Testing: 3.80 runner in the 30-yard dash; 24.20-inch max vertical jump.
Vizual Edge: 77.85 Edge Score.
Positional Profile: OF/LHP
Body: 5-10, 145-pounds. Wiry, lean frame with room to add on strength.
Delivery: Loose, athletic delivery, controlled leg-lift into balance point, sits into back leg and rides it down the mound, stride works in-line with a closed landing foot.
Arm Action: LH. Loose, easy arm, long in the back into a low 3/4 release.
FB: T78, 76-78 mph. Plays with heavy sinking action to the arm-side. T1831, 1749 average rpm.
CH: 74-76 mph. Similar profile to the fastball, sinking/running action, landed for some strikes, missed up at times. T1669, 1580 average rpm.
Positional Profile: OF/LHP
Body: 5-10, 145-pounds. Wiry, lean frame with room to add on strength.
Hit: LHH. Crouched, athletic stance, small up/down leg lift. Hands drop into a flat path, some rhythm in the hands, balanced and controlled finish. 60 mph bat speed with 6 G’s of rotational acceleration.
Power: 82 max exit velocity, averaged 77.4 mph. 251’ max distance.
Arm: LH. OF - 85 mph. Loose, quick arm action, 3/4 arm slot.
Defense: Easy, athletic actions, long quick-strided and plays through in rhyhtm.
Run: 4.12 30-yard dash.
