The World Series League had its beginnings in 2003 and sprang from the previous Triangle Series played since 2000, involving Mad Dogs, Staten Island and Gypsies cricket clubs. The games, played on Saturdays, complemented the larger number of Saturday friendly games. In 2003, the Triangle Series was laid to rest and the World Series League was born, including the three teams of the Triangle Series and adding two new teams, UBS and Hoboken, for a total of five teams. 

Although teams have dropped out of the league, new teams have joined allowing the league to expand. In 2017 the league consisted of seven teams, probably the maximum number of teams that can be accommodated without discarding some of the traditional non-league cricket the club plays on Saturdays. There frequently are other teams seeking to join the WSL.

The WSL follows traditional cricket practices. There are no power plays, no 15-yard or other circles. The format is 35 overs. A ball is not wide simply because it goes down leg side. The matches are competitive and given the rules that govern the league, among them: fair play, respect for other players and consideration for all, behavior is largely within the rules. Players report, on a whole, that the games are enjoyable and they look forward to these Saturday engagements.
