Here’s a link to the USA Baseball approved bat list. There are links to where families can go to purchase a particular model.
As I have said previously, in theory all bats will perform about the same under the new standard, so families should consider this as they make a selection. While this is an approved list, the primary requirement to look for is the USA Baseball insignia prominently embossed on the throat of the bat (for Junior level and below.) For Senior Baseball, the BBCOR standard still applies. Ask families to be careful to look for this designation and avoid the confusion of any other designation that uses the word “approved.” When in doubt, this list should be particularly helpful.
Be careful before you buy a new bat as Little League Baseball, not WSLL, is changing bat standards for the 2018 season.
