Intermediate, Junior, and Senior League Baseball are youth baseball divisions of Little League Baseball that are considered more advanced and difficult than younger Little League divisions due to more advanced rules, including the ability to lead-off and steal as the pitcher breaks, along with longer base paths and greater pitching distance. Junior League also includes the use of bats with 2+5⁄8-inch (6.7 cm) barrels rather than the transitional 2+1⁄4-inch (5.7 cm) barrels of Little League. Junior League also allows the use of metal spikes in cleats in addition to the molded or plastic spikes used in Little League. The Big League level was discontinued in the baseball and softball divisions — after the 2016 Big League World Series.
