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.
Positional Profile: 3B/SS
Body: 5-10.4, 171.5-pounds. Lean, athletic frame with more room to add strength in the future.
Hit: RHH. Upright setup, quiet hands pre-pitch, toe-tap stride, utilizes lower half. Loose, longer path, line drive oriented to the middle/pull-side. 72.5 mph bat speed with 15g of rotational acceleration.
Power: 98 mph max exit velocity (88.8 avg.); 351-foot max batted distance.
Arm: RH. INF - 84 mph. 3/4 slot, easy.
Defense: Works around, steady one hand gather, clean double play turn, natural feel for the position.
Athletic Testing: 7.27 runner in the 60-yard dash; 21.10-inch max vertical jump.
Vizual Edge: 74.06 Edge Score.
Delivery: Deliberate delivery, high leg lift, tall and fall, smooth and loose actions.
Arm Action: RH. Compact, short arm action, 3/4 slot.
FB: T85, 81-84 mph. Easy out of hand, locates. T2211, 2050 average rpm.
CB: 72-74 mph. 11/5 break with feel. T2274, 2159 average rpm.
CH: 79-79 mph. Fastball intent, keeps low. T1703, 1703 average rpm.
Uncommitted. Stands in a 5-foot-10, 165-pound frame with more room to fill out. Pitched a perfect inning in relief for the Crusaders on Friday, collecting two strikeouts. Attacked hitters with a FB that sat 83-85 (T86) with arm-side run. Also flashed a low-70s SL with late 10/4 bite and showed an ability to locate the pitch glove side for swing-and-miss. Pitched with ease and athleticism down the mound with a low-tempo delivery, showed repeatability with a loose arm action. On Saturday, started on the mound. Settled in after the first, throwing four innings with two earned runs. He did damage at the plate going 3-for-4 with one RBI. Launched a solo home run to start the game, followed that up with two hard-hit singles to center. Must-know name in the 2027 class.
RHP Griffin Dobberstein (Ottawa Marquette, 2027) is an athletic mover on the mound with a projectable frame at 5-foot-9, 160 pounds. A two-way talent, he played on the infield in the 1A State Tournament enroute to the Crusader’s 1A State Title, further showcasing his athleticism. His fastball sat in the low-80s, T81.8 mph, with a curveball (67-68 mph) and changeup (73-74 mph) as secondary offerings. While the velocity isn’t there yet, his clean movement and overall athleticism suggest more is in the tank as he continues to develop. A name to watch in-game this spring and summer. On the other side of the ball, the right-handed hitter showed a whippy barrel and operation, working to stay up the middle of the field, upside swing, reaching up to 91 mph for his EV.
