The expanded usage of data, and the importance of it in regards to player development and player assessment is a legitimate, undeniable tool used by high school, college, and professional teams across the country. Today we break down some of the data from the Mid-Atlantic ProCase event in Richmond, VA. 



Had the highest average bat speed (77.0 mph), and in turn produced the highest max EV (exit velocity). Though he had 8th highest average EV. This is because 73.7% of his batted balls were with LA’s (launch angle) greater than 10 degrees. He has an average AA (attack angle) of 5 degrees, so his best batted balls come at lower LA’s instead of higher ones. He combines high end hand speed (22.4 mph) with high end rotational acceleration (RA); his average RA (23.97) was actually 9.98g higher than the average hitters in affiliate ball. 



Had one of the steeper VBA’s, with an average of -33 degrees, and the steepest coming at -45. When you combine a steep bat path with an average bat speed (75.1 mph) 12.7 mph quicker than the high school average, you get an average EV of 95.8 mph with 85.7% of the batted balls being equal to or greater than 90 mph. He hit the farthest projected ball (393 feet), and third hardest ball at 104.1 mph while putting it in play at a LA 25 degrees or steeper 42.9% of the time. The high end EV’s coming at ideal ball flights lead to home runs and the steep bat path leads to an increased probability in Nathan running high BABIP’s due to his ability to hit his miss-hits with authority.

 


Had the 11th highest average EV (86.2 mph) while having the 4th highest rate of batted balls steeper than 25 degrees. He was also 1 of just 7 players to record an EV in the triple-digits, and hit the least amount of batted balls under 25 degrees of the 7 players. Peak EV’s tend to come at lower LA’s (usually around zero, and the farther you get, the lower the Peak EV is) so the ability to produce high exit velocities at uncommon flights is unique, which Trimble does. Average VBA (vertical bat angle) was -27 degrees with the steepest being -33, and the flattest being -17. His farthest projected batted ball distance was 390 feet, the second highest of the event. His average bat speed (73.9 mph) was also 11.5 mph higher than the high school average.
