Illegal Bat List for ASA Softball

The Amateur Softball Association is one of the major organizations that oversees softball for both kids and adults. While it certainly takes fairness into account when it makes rules regarding the legality of certain bats, the biggest reason is player safety. ASA, therefore, tests bats and places those that generate too much power on an illegal bat list, banning them from use. ASA standards are stricter than other major softball organizations.


Worth has been in the business of manufacturing and marketing baseball and softball equipment for nearly 80 years. It was the first company to begin making aluminum bats in 1970. ASA has toughened its standards over the years, and each time it has lowered the allowed speed generated by bats, Worth has complied by creating bats that meet the standard. The ASA illegal bat list includes a number of Worth bats, but none are in their current (as of June 2010) year's line of softball equipment. The illegal bats are the EST9, QESTFP, SWBK, SWBKA, WWSC, WWSCA, XEST9X, XGold, XPST4, XRed and XWickX.


Easton has built a line of bats that conform with the United States Specialty Sports Association standards rather than those imposed by ASA. The USSSA allows for a greater ball speed off the bat than ASA. Its Synergy line of bats has two in particular--SCX2 Synergy and SCX22 Synergy 2--that appear on the illegal bat list for ASA.

Louisville Slugger

The longest operating bat manufacturer is Louisville Slugger. The company began making baseball bats in 1894 and has been one of the leading baseball and softball equipment providers around. Louisville Slugger likes to be a leader in using technology in the design of its bats, in order to provide the most competitive products on the market. Its FBC305 Catalyst, SB304, SB34 Genesis and SB404 bats are on ASA's list of banned bats.


Miken is another bat company that likes to be where the technology takes them. They have created a line of bats that conform to the more relaxed USSSA standards, but are not acceptable for ASA play. The bats include the MSF Freak, Ultra, Ultra II and Ultra Maxload models.
