About Us
Welcome to SEMA Baseball!
This is the unified home of youth baseball in Southeastern Massachusetts, bringing together the best of the Hockomock Summer Baseball League (HSL) and the Massasoit Spring League (MSL). Hockomock Summer League (HSL), founded in 1995, began as a single-division summer league for 8U–18U players and has grown into a multi-division, high-quality competitive environment throughout the region. Meanwhile, MSL has provided a strong spring season platform for towns and players to compete and engage in youth baseball across the area focused on Middle and High School baseball players age 13 & 14U (Juniors) with 15U+ (Seniors)
The Hockomock Board merged with the Massasoit Spring League in 2025 combining our strengths and scale under a new organization called SEMA Baseball, we aim to create a seamless baseball experience across seasons with development, competition, and community at our core. Our mission is to foster teamwork, respect, sportsmanship, and a love for the game in every player, coach and family involved. Together, we offer spring and summer opportunities ensuring young athletes can stay in the game, grow their skills, and represent their towns with pride.
