What is BBCOR?

So what is BBCOR, and why do we need to know this for baseball?

BBCOR literally stands for "Batted Ball Coefficient of Restitution".

I know...sounds all complicated right?

Basically it determines the "bounciness" of the ball coming off the bat.

You need to make sure your bat is a BBCOR certified bat or you could be buying a bat that your child cannot use in any of their games at all!

There will be a BBCOR certified mark directly on the bat (as shown below), so you will definitely know it meets the new standard. It needs to be less than or equal to .500.

What is a BBCOR Bat?

A BBCOR bat is a standard of bat that is inforced by the NCAA (National Colliegiate Athletic Association) and the NFHS (National Federation of State School Associations) as a safety measure to pitchers, infielders and fans of the game.

Colleges (NCAA) started requiring the BBCOR standard in the 2011 season, and as of January 1, 2012 high schools (NFHS) began using this standard as well.

Going forward, this BBCOR standard baseball bat is to be used at the high school level and above.

The BBCOR standard replaces the old BESR (Ball Exit Speed Ratio) standard.

The BESR standard was no longer considered to be as accurate in determining the performance between different bat models.


BESR bats are the old standard for baseball bats, so you need to be sure you have the new standard BBCOR certified bat when playing baseball at the high school or above.

Many youth baseball leagues are also adopting the BBCOR certified bats, so you need to check with the coach of your team before buying your youth baseball bat.

The BESR bat has been known to hit a ball as fat as 115 miles per hour, which is a dangerous speed for infielders and fans in the foul zone.

Now with the BBCOR bat, the players and fans have more reaction time.

With the 5-6% decrease in performance of the BBCOR bat, it makes baseball games more "balanced" among players as well as being safer.
