Baseball & Softball Leagues for Mountainside Youth since 1954
Recreation League
The purpose of our Spring Recreation program is to give young girls & boys an opportunity to learn to play softball & baseball in a fun and local environment.
Travel League
Our Travel League teams provide opportunities for players to compete at a higher level than our Recreation Leagues offer. Players possess the desire to more actively hone their skills with like-minded peers.
Tournaments
MSBL participates in, and occasionally hosts, softball & baseball tournaments, giving our teams a chance to compete with teams near and far.
Clinics
MSBL will alert the community to camps & clinics throughout the year. These are opportunities for players to improve skills such as hitting, pitching, catching or fielding.
Junior Umpires
The Junior Umpire program gives youth (ages 12 and up) the opportunity to learn the fundamentals of officiating while developing leadership, confidence, and a deeper understanding of the sport.
