As an 8th grader, AJ started at BRX with a below average arm for his age at 62 MPH.
Over the next 18 months, he made one of the most impressive throwing velocity improvements we've ever seen.
At his first showcase his freshman year, he threw 84 MPH across the diamond - that was the second highest in the ENTIRE state of Wisconsin!
You might be thinking, "Well he just got older and taller."
While that's certainly part of it, after compiling a mountain of showcase data, we found that the average throwing velocity improvement for players AJ's age over the same time span is only 6 MPH.
AJ nearly quadrupled it!
