New for 2027: tee ball bats can only be used with low-compression balls. They're not legal in 6U Coach Pitch or any pitched-ball division, or in 6U/8U tournaments.
What the stamps mean
- USA Baseball (USABat) mark: USA Baseball's youth standard, which makes bats perform close to wood. Barrel up to 2 5/8", no drop limit, and no new USABat is made longer than 32". Required in Little League, Cal Ripken, PONY, Diamond Youth (Dixie), AABC and most rec leagues. Official list.
- USA Baseball tee ball mark ("Only for use with approved tee balls"): Tee ball bats carry the USA Baseball mark plus "Only for use with approved tee balls". They're legal only with approved low-compression tee balls, never with a regular pitched baseball. Official list.
- one-piece solid wood: One-piece solid wood is legal almost everywhere without a stamp. Multi-piece, laminated, bamboo and composite-wood bats usually do need a certification mark.
