wholesale blank baseball caps,
Our baseball athletes are always looking to the future. They are training for their next game, drilling for the next level of performance and trying to find the perfect bat. wholesale blank baseball caps , We love that about them.
It's time to get serious about BBCOR. This new standard measures bat performance and replaces the old standard called BESR. Starting in January 2011 for NCAA (college level) play and January 2012 for NFHS (high school level) play, all bats must be BBCOR certified. BESR (Ball Exit Speed Ratio) is no longer considered accurate enough to determine the actual performance of differing bat models.
What is BBCOR?
BBCOR (Batted Ball Coefficient of Restitution) is a name convoluted enough to make even the geekiest ballplayer gulp. We'll try to explain it to you as best as we can.
Instead of measuring the speed of the ball after it is batted, BBCOR measures the "bounciness" of the ball and bat, or the "trampoline" effect. Whenever a bat hits a ball during a game, the ball actually compresses by nearly a third. red bull hat , cheap fitted hats wholesale ,
A pitched ball holds a lot of energy that you can see in the spin and speed of the ball. With solid wood bats, much of that energy is lost as the ball compresses at impact. The batted ball speed gets a lot of its energy from the bat. With hollow-core aluminum or composite bats, the thin walls "give" a little, and the ball distorts less and retains its pitched energy and adds to it the power of the bat speed. That's why non-wood bats hit balls faster.
