COYBL
Last updated August 6, 2026
USA Baseball publishes the safety and coaching material COYBL's rules are built on. These are the three worth knowing.
The pitching limits COYBL enforces come from Pitch Smart, a joint USA Baseball and Major League Baseball programme built around protecting young arms.
Our own limits, by age group, are on the Pitch Counts page and in the league rules.
BASE is USA Baseball's athlete safety hub. It is where the Abuse Awareness for Adults course lives, which federal law requires every coach and every adult who interacts with your team to complete once.
Step-by-step instructions for creating your account and taking the course are on the Player Safety page.
USA Baseball's manual for coaches, covering practice planning, skill development, and age-appropriate expectations. Free to read.
