ASA Ban Bat list.

New National Guidelines for Banned Bat Recognition
1/22/2008 - The ASA recently changed the non approved bat listings located at  This was a recommendation by the ASA Equipment Testing and Certification Committee.  The reasoning behind this was an attempt to make it easier for ASA leagues, tournament directors and umpires to clarify questions surrounding legal and/or illegal bats.

The original master list has been removed and replaced with two lists that separate bats that have been declared illegal that bear the 2000 mark and bats that bear both the 2000 and 2004 mark.  This master list contained bats that were never intended to be certified by ASA that were made by bat manufacturers.  The committee felt like this was confusing the issue and making it more complex than needed out in the field. 

Bat manufacturers, against ASA’s guidance, will continue making bats intended for HR derby’s, outlaw leagues and other associations thus making it nearly impossible to continue listing every non-certified bat along with a photo.  All of these new non ASA certified bats do not contain the ASA certification mark so the easy answer for umpires and league/tournament directors is as follows:

Choosing the right bat

  One of the most frequent questions I get ask from parents and some coaches is

          “How do I choose the right bat for my daughter”  


 Simply choosing the right bat for a player can make a huge difference in how they swing and what kind of results they get. The bat determines the velocity of the swing, the strength of the impact with the ball and how far the ball will go. It also controls the aim of the ball and affects the beginning of the batter’s sprint to first base. Because the bat affects so many aspects of the game, having the right bat is essential. 


 There are two main characteristics to look for with a bat: length and weight. A bat that is too short will not allow the batter to hit all the balls in their strike zone, even if the batter knows they should be able to reach it. It might cause them to reach for the ball, which throws off their stance, rhythm, and ability to get behind the ball with real power.A bat that is too long is often also too heavy. This will make the swing slower and the motion clumsier.A bat that is too long also puts the batter at danger for hitting the ball with the wrong section of the bat, making the ball go in a different direction than intended.To pick a bat that is the right length for the player, batters should stand in the middle of the batter’s box and place the bat against the inside corner of home plate. The knob of the bat should come to the batter’s palm. If the bat is too short, it will only reach to the fingers. If the bat is too long, it will go up to their wrist and beyond.  


  A bat’s weight is extremely important to the overall swing and success of the bat. Normal bats are 8-11 ounces less in weight than their length in inches. So, for example, a bat that is 30 inches long will probably weight about 20 ounces. A bat that is too heavy will slow down the swing and make it very difficult for batters to maintain proper form during the stance and swing. Starting with improper form only leads to improper form in swinging, which reduces the chances for a well-hit ball that will result in a base hit.A bat that is too light will cause batters to swing too fast, which also affects rhythm and keeps the batter from doing their job. A light bat also sometimes causes the shoulders to get ahead of the hips. In an effective swing, the hips should lead the rest of the body. If the shoulders get around too quickly, the swing will not have proper power, as much of the batter’s power comes from the action of the hips, which lead the lower body. 

Follow Regulations 

With aluminum and composites bats becoming more popular and allowing batters to hit faster, longer balls, many associations and leagues have developed rules regarding the use of these bats.  Please before you make that expensive purchase please down load the latest banned bat list. You don’t want to find out later your new bat is now illegal. 


I hope this helps.
