WBSI is a 501(c)(3) non-profit, all-volunteer organization offering baseball and softball leagues for children ages 4-15. Our coaches teach the fundamentals, while promoting fun, teamwork, good sportsmanship, and a love of the game. We are based in Warren, New Jersey.

Leagues are organized by grade level:

• T-Ball is open to boys and girls in grades Pre-K and Kindergarten.
• Softball is open to girls in Kindergarten through 8th grade who live in Warren, Watchung, or Green Brook.
• Baseball is open to boys in 1st to 6th grades who live in Warren Township.
• Buddy Ball, our special needs program, is open to individuals age 5-20.

In addition to our spring recreation season, WBSI provides opportunities for players to participate in spring, summer, and fall travel baseball and softball.

WBSI is a charter member of Cal Ripken/Babe Ruth Baseball League since the 1990s and a member of the Middle Atlantic Region Babe Ruth League, Northern New Jersey, District 12.

We rely on the support and contributions of volunteers and sponsors to make WBSI one of the best youth leagues in the area. There are many ways to get involved: as a coach, assistant coach, team parent, and sponsor. We all share a common thread – we do it for the kids!
