BaseballSoftballUK (BSUK) and the British Softball Federation (BSF) are proud to announce the launch of the Slowpitch Open Series – two new tournaments to help fill out the softball calendar following the withdrawal of Diamond Series tournaments in 2022.

Following the cancellation of the Diamonds Series earlier this month, BSUK and the BSF wanted to ensure that teams that usually participated in the tournament would still have the opportunity to play slowpitch softball this year.

The result is two new tournaments: the May Cup and the June Cup.

The Softball Open Series – which also includes the annual BSUK Slowpitch Cups – is designed to give as many players as possible across all levels of ability the opportunity to play softball throughout the main competition season.

The May Cup will take place on 14-15 May while the June Cup will be on 18-19 June.  Both tournaments will take place at the Farnham Park National Baseball & Softball Complex in Buckinghamshire.

Any profits generated from the new Slowpitch Open Series will be invested directly into the development of baseball and softball, including the day-to-day operation of Farnham Park, in line with BSUK’s mission and not-for-profit status.

May Cup – 14 + 15 May

The May Cup is open to 32 teams, with eight places available in the B division and 12 places each in two REC Divisions.  REC will be divided into Upper and Lower Divisions.

June Cup - 18+19 June

The June Cup will feature 24 teams, with eight places available in the B division, eight in the Upper REC Division, and eight in the Lower REC Division.
