2018 Bat Rules
Any bats that meet CIF baseball bat standards (see www.cifstate.org) which are BBCOR approved. The BBCOR stamp must be affixed to the bat. This category must follow a -3 weight to length ratio as described in the BBCOR approved baseball bats list. In summary, any BBCOR stamped and approved bat with a -3 weight to length ratio, whether “all aluminum” alloy or composite is allowed.
Any “all aluminum” alloy baseball bats are allowed (regardless of weight to length ratio). Any wood bats allowed except for bamboo.
Bats with a barrel larger than 2-5/8” and any composite bats that are not BBCOR -3 are not allowed (e.g., -10 Mako).

The bat must be a baseball bat which meets the USA Baseball Bat standard (USABat) as adopted by Little League.

All BPF – 1.15 bats will be prohibited beginning with the 2018 season. Additionally, the bat diameter shall not exceed 2⅝ inches for these divisions of play.
Under the USABat standard, certified Tee Ball bats (26″ and shorter) will feature the USA Baseball mark and text which reads ONLY FOR USE WITH APPROVED TEE BALLS. New bats with the USA Baseball mark as well as “all aluminum” alloy bats (26” and shorter) that were produced and/or purchased prior to the implementation of the new standard are allowed.
