In 1921, the Barnstable County Agricultural Society determined to limit the fair's annual baseball championship to teams from Cape Cod.

One notable player during this period was North Truro native Danny "Deacon" MacFayden, who went on to play for seventeen years in the major leagues.

However, as the cumulative effects of the Great Depression made it increasingly more difficult to secure funding for teams, the Cape League disbanded in 1940.

The league would no longer be limited to Cape Cod residents, but would recruit college players and coaches from an increasingly wide radius.

[15] This transition began a period of significant growth in the league's popularity and prestige among MLB scouts, as well as among college players and coaches.

This popularity has translated into over one thousand former players who have gone on to major league playing careers, including multiple members of the National Baseball Hall of Fame.

Following the regular season, the top four teams in each division qualify for the playoffs, which is an elimination tournament consisting of three rounds of best of three series to determine the league champion and winner of the Arnold Mycock trophy.

However, in late 2008 MLB announced that it would enforce its trademarks, and required those CCBL teams to either change their nicknames or buy their uniforms and merchandise only through MLB-licensed vendors.

The four teams whose nicknames were not in conflict with MLB have locally themed names such as the nautical monikers of the Falmouth Commodores and Brewster Whitecaps.

The Cotuit Kettleers nickname recalls a legendary local Native American land transaction whose terms of sale involved the exchange of a brass kettle.

Present Day In 1988, the Bourne Braves and the Brewster Whitecaps joined the CCBL as expansion teams and the resulting ten-team league was split into East and West divisions.

The first CCBL All-Star Game took place in 1946, as a squad of Cape League stars battled a collection of Boston Red Sox tryout players.

Ballantine was a major advertising sponsor of the New York Yankees, and arranged for appearances at the CCBL festivities by Yankee alumni including Phil Rizzuto, Elston Howard, Whitey Ford, Moose Skowron, Bill Stafford, Eddie Lopat, and Mel Allen, as well as Brooklyn Dodgers great Roy Campanella.

In addition to the player inductees below, Cooperstown also honored longtime CCBL president Judy Walden Scarafile in 2010 by featuring her in the museum's Diamond Dreams exhibit, which highlights stories of pioneering women in baseball.
