Prep Baseball Report

Underclass Games: Blast Leaderboard

Brett Thorney
State Scouting Director

On Wednesday, June 16th PBR Arizona had a chance to hold its Underclass Games. This event is held at the beginning of the summer each year and gives us an opportunity to start to get a feel for some of the younger prospects that our state has to offer. This event features some of the top prospects in the 2024-2025 grad class from all around the state of Arizona. This has become a popular event as players start to get their names out there and start their HS baseball careers.

The event at Cactus Shadows included 35 + players including 13 pitchers that participated in a pro-style workout followed by simulated game play. As always, we gathered loads of valuable information on players that will live in player profiles that include Trackman & Blast data as well as 60-yard dash, positional velocities and more. Surly progress will be made in these statistics while players get older and mature physically but players were able to get a baseline of data to help understand their starting points. Scouts will use this information along with video to start to separate players more in the future.

Since the beginning of the summer, one of the important tools Prep Baseball Report has started to implement at its events is the use of Blast Motion sensors. During batting practice, the Blast Motion sensors measure Swing and Impact Metrics across several categories. Swing metrics measure pre-impact mechanics centered around plane, connection, and rotation while Impact metrics measure pre-impact performance outcomes based on ball contact.


Top AVG Bat Speed: 72.93mph | 2024 Brody Matcuk (Chandler)

Top PEAK Hand Speed: 26.73mph | 2024 Brody Matcuk (Chandler)

On-Plane Efficiency: 85% | 2024 Gavin Short (Sunnyslope)

Rotational Acceleration: 34.58g | 2024 Oscar Rocha (Salpointe Catholic)

Below will you find the swing & impact metrics from the event in four different categories (Top-10 listed):
