MYBL is a member of PONY Baseball, Inc. MYBL is one of the largest youth baseball organizations in the western San Gabriel Valley. The PONY program provides flexible rules and incremental levels of competitive play, which are specifically designed for the physical development and safety requirements of each age group. Baseball play is governed by the Official Rules of Major League Baseball and PONY Baseball rules and regulations. The game of baseball you watch on TV or when you are at a Major League ballpark is the type of baseball we play at MYBL. Our league is committed to balanced teams and fair play and to provide a clean, supportive, and competitive atmosphere.
