Wequassett Beach
Call: (508) 432-5400

Join players from the Harwich Mariners for a morning of beach baseball and fun!

Young guests can enjoy a casual game, learn a few skills from the players, and spend time with athletes from the Cape Cod Baseball League — the nation’s premier collegiate summer baseball league and a longtime Cape Cod tradition.

Children and adults play and walk on a sandy beach near a body of water under a clear blue sky. Some people are near the shore, while others are farther back on the sand, perhaps enjoying the coastal atmosphere that makes Cape Cod Baseball with the Harwich Mariners such a local summer tradition.

Q&A

A: Reservations are not required for this complimentary event however parental supervision is.

A: Harwich Mariners provide bats, gloves, and balls, though guests are welcome to bring their own equipment. You may also wish to bring something for the players to sign—MLB stars including Ian Happ, Cavan Biggio, and Aaron Nola once played on the Cape, so you never know where today’s players may end up.

Whitehouse Field, located at 75 Oak Street in Harwich, is the home field of the Mariners. Most home games begin at 6:30 p.m., and the 2026 summer schedule can be viewed here.

The Cape Cod Baseball League traces its roots back to 1885, when local town teams across Cape Cod began competing against one another during the summer months. The modern league officially formed in 1923 and has since grown into the country’s premier collegiate summer baseball league. Known for its use of wooden bats and elite level of competition, the Cape League attracts many of the top college baseball players in the nation each summer.

More than 1,600 former players have gone on to play in Major League Baseball, including Hall of Famers, MVPs, Cy Young winners, and World Series champions. Today, the league includes ten teams representing Cape Cod communities, preserving a classic New England baseball tradition while serving as one of the most respected pipelines to professional baseball.
