Why teams play the Diamond Series

Competitive, not cutthroat

Each weekend stands on its own. No points chase, no bids. Coaches pick the A or B level that fits their team, so kids get games they can learn from.

You know where you're playing

Every game is at the Laurence Harbor Baseball Complex, 11 Ely Avenue. No "venue TBD 10 days out." Plan the day the moment you register.

Everything posted

Fees, rules, refund and rainout policies are all on this site before you pay. No account, no cart: register, pay with Venmo, done.

Built around the field

46/60 for 9U–10U, 50/70 for 11U–12U and 60/90 for 13U–18U. Each age plays on the right-size field with the right bats.
