Bat requirements vary at different ages across our House and Travel leagues.  Here is a summary of the requirements for each age level in 2024.  The 2024 bat requirements are the same as they were in 2023.

The two primary bat standards are USSSA 1.15 bpf and USA Baseball.  The bat is stamped with the standard's logo just above the handle, as shown below. 

Both USSSA and USA Baseball stamped bats are allowed in all PWYBA House leagues and 9-14U Travel leagues.

For each age level below, the weight differential is the difference between the length (in inches) and weight (in ounces).  For example, a 29", 19 oz bat has a -10 weight differential.
