Monrovia Youth Baseball League (MYBL), an affiliate of PONY Baseball (Protect Our Nation’s Youth) and a registered non-profit organization, is dedicated to serving hundreds of young athletes and their families throughout Monrovia, California, and the surrounding communities of the San Gabriel Valley, since 1956.

Our mission is to provide every child—regardless of skill level, experience, or financial circumstances—with the opportunity to participate in organized youth baseball. We strive to create a safe, inclusive, and positive environment where players can learn and develop the fundamental skills of baseball, while also building character through the values of teamwork, respect, sportsmanship, and perseverance.

As part of the PONY Baseball family, MYBL is committed to fostering personal growth and community connection through America's favorite pastime. Our goal is not only to teach the game of baseball, but also to help shape confident, responsible, and resilient young individuals—both on and off the field.
