Fastball
Hop+
A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.
Fastball
Sink+
A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.
Fastball
Rise+
A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
Slider
Hammer+
A hammer breaking ball drops vertically with velocity through the zone, or 12-to-6 movement. Hammer+ of 100 is MLB average.
Slider
Sweep+
A sweeping breaking ball moves horizontally with velocity through the zone. Sweep+ of 100 is MLB average.

Tanner Buhlmann, Arrowhead (WI), 2026
Positional Profile: LHP/OF
Body: 5-9, 165-pounds. Wiry build, more fill and strength coming.
Delivery: Side step into higher leg lift, drop and drive downhill, athletic and simple.
Arm Action: LH. Longer action out of glove, loose, 3/4 slot.

The southpaw utilized a two-pitch mix to earn 11 strikeouts complete game, shut-out efforts. His fastball sat in the high-70s throughout his appearance, topping at 81 mph early on and it played with some hard running action, too. His breaking ball sat in the high-60s, featuring lateral action with 2/8 shape and he also flashed a running changeup, too. The pitchability that Buhlmann currently possesses is noteworthy and he is certainly a name to follow as he continues to develop as a prospect.

Power: 80 max exit velocity, averaged 70.8 MPH. 254' max distance.
Arm: LH. OF-76 mph. Medium arc, 3/4 slot, quick arm.
Defense: Shuffle-step gather, good direction good lines.
Run: 7.62 runner in the 60.

LHP/OF Tanner Buhlmann (Arrowhead, 2026) was another freshman from the event that jumped out to our staff. Listed at 5-foot-8, 140 pounds, the lefty is athletic and well-proportioned with strength coming as he matures. On the mound, he showed a loose and clean arm, and a fastball that sat 75-76 mph with run to the arm side. His slider showed lateral action with a 2/8 shape. When throwing his changeup, he maintained fastball arm speed and he was able to create fade to his arm side.
