Findings

2024 was the first full season of implementation of ProBAT's CORTester by a number of MLB organizations.

Hundreds of bats were tested and labeled successfully across the league objectively increasing exit velocities while giving player's complete confidence in their bat selection before they step into the box.

2024 Spring Training

The bats pictured were part of 6 new, identical bats brought to us by a player for testing in 2024 Spring Training. Out of his preseason batch, the variance was obvious:

Results:

Best Bat: 31 RS#
Worst Bat: 21 RS#
Swing your best bat!

This could mean as much as a 5 mph difference in exit velocity this player could gain by differentiating his "gamer" bat from his "cage" bat.

Swing your best bat!

Record Breaking Technology

The hardest hit ball in MLB history was recorded this past season at 122.4 mph off the bat. Prior to the AB, our CORTester was utilized to pick out the optimal bat in the player's batch which graded out to a 33 RS# (average is ~27 RS#).

Player Application

Players are depending on it to help them pick their gamers. They have INCREASED CONFIDENCE each and every time they step in the box!
The full 4-quadrant test is helping players maximize their "pop" by identifying the best impact surface quadrant
Players that are feeling "soft" bats that are not giving the performance expected are being confirmed by the CORTester testing out with lower RS#'s

CORTester Results to Date

31-35

The cream of the crop. These are top tier RS#'s we've seen, the types of bats you want to get into your players' hands.

24-30

Good wood. This the the average range we have found after testing hundreds of bats.

15 (or less)-23

Time to take these bats out of game play and designate them for cage work only.

What's the Verdict?

After testing hundreds of bats, there is no clear "winner" among bat manufacturers or bat wood type (maple, birch, etc...). There is also no way to 100% predict the best impact surface or quadrant (edge grain, face grain, etc...). The virgin wood quality along with the manufacturing processes (sanding, boning, finishing, etc...) affect the rebound strength of the finished bat. Therefore, it is important to test each bat on-site to maximize each hitter's potential for each at-bat.
