Several have wondered what leagues are effected by USABats. The chart below helps to clear up much of those problems. Leagues affiliated with Little League are more than likely going to the new USABat standard. That includes places like Cal Ripken, Babe Ruth and Dixie Youth or Pony. Other leagues, like USSSA Baseball and major travel ball leagues are tending to stay with the USSSA 1.15 BPF stamped bats.
In short, it depends.
You will not need to buy a USAbat if you…
Are at least 12 years old at the moment (2016)*
Don’t play in the leagues whose national affiliate requires AND the local league enforces the new standard.
It is possible you will never be in a league where USAbats are required. The standard will be implemented while you may be going into 14 year old baseball (2018) and most 14 year old baseball is BBCOR. BBCOR is not being replaced by USAbats.
The National Affiliations are: American Amateur Baseball Congress (AABC), Amateur Athletic Union (AAU), Babe Ruth Baseball/Cal Ripken Baseball, Dixie Youth Baseball, Little League Baseball and PONY Baseball.
It is possible many local leagues will not enforce the bat rules until a later date than January 2018. This will give many of those BPF 1.15 bats a chance to live their useful life.
You will need to buy a USAbat if you…
Are still young enough to play in the Little League World Series for 2018
Play in a league that is affiliated with a USABats national association AND the local league enforces the rules on day one.
NOTE: Many local leagues have a lot of liberty in terms of what rules they enforce. If you want to play in the national or state tournaments sponsored by these associations, then you will need the new USAbat starting 1/1/2018.
