Bat rules for baseball and softball · 2026 Edition Certification lists last checked September 25, 2026

For parents buying a bat

Know your bat is legal before the umpire checks it

Bat certifications change every season. Models get pulled from approved lists mid year. Rules differ by league and age division. Pick your bat and your league to see if it is legal, which stamp it carries, and any known decertification.

Three checks before you buy

2.01

The stamp is checked

Every non-wood bat carries a certification mark: USA Baseball, USSSA 1.15 BPF, or BBCOR .50. Your league accepts only certain stamps. The wrong stamp means the bat is not legal; a USSSA bat is never legal in Little League, no matter its price.

2.02

The list is checked

A stamp is not the final word. Certifying bodies test retail bats continuously and decertify models that drift out of spec, sometimes in a single length. A bat is legal only if it is on the current approved list and not on any banned or withdrawn list.

2.03

The limits are checked

Divisions cap drop weight and barrel diameter, and the caps move; USSSA 14U changed to BBCOR minus 3 on January 1, 2026. Your bat's drop and barrel have to fit your division's limits.

The three baseball bat stamps

Every legal non-wood youth and high school baseball bat carries one of three certification marks, and each mark is accepted in specific leagues. Softball uses its own marks.

USA Bat

The rec league standard

Required in Little League Majors and below, and standard across Cal Ripken, Babe Ruth, PONY, and Dixie. Performs closer to wood by design. Also accepted at USSSA events where BBCOR is not required.

1.15 BPF

The travel ball standard

The USSSA thumbprint mark, legal in travel play through 13U. Hotter than USA bats and never legal in Little League. As of 2026, no longer the 14U national standard.

Full Rule →
BBCOR .50

The big field standard

Required in high school, college, Little League Senior, and USSSA 14U national play from 2026. Always a drop 3, always certified by the WSU Sports Science Lab.
