For Pony, Cal Ripken, Babe Ruth, Dixie, and AABC, new 2018 Baseball bats must be approved and showing a 2018 USA Bat Stamp. On January 1, 2018, USA Baseball adopted a new bat standard. On December 30, 2010, officials announced a moratorium on using and Composite bat in all divisions and during the Little League World Series.Several manufacturers of BBCOR Baseball bats have subsequently obtained International approval for specific Composites. The rules committee met on August 17, 2009, to discuss their proposal with manufacturers, and on August 24, the NCAA Playing Rules Oversight Panel approved a temporary ban on any BBCOR bats made with composite materials. On July 22, 2009, the NCAA reported that the rules committee had requested to ban the use of composites. There are five main advantages for using composite: swing weight, trampoline effect, bending stiffness, bending vibrations, and sound.įor a time, the future of the Composite baseball bat at the collegiate level was in question. As has been chronicled in slow-pitch softball recently, a bat made from Composite Materials has outperformed the standard aluminum bat. There are many advantages to using composite compared to Aluminum. The Composite polymers used in a composite bat can be susceptible to cracking if used in cold temperatures. The most notable concern is the use in cold temperatures. When it comes to a Baseball bat and its performance there are very few disadvantages. MLB or affiliates for short season and rookie ball does allow a select few composite wood bats. Instead of swinging a 31 or 32, they could handle a 33- or 34-inch bat. No Metal or Composite BBCOR Bats are allowed in the MLB or its affiliates. The Green Easton, the B5 Pro, a 71/78 aluminum alloy with a 2-5/8 barrel diameter, changed the game by dropping weight. High school (NFHS) and Collegiate play are governed under the BBCOR Bats standards.
