Greater London Softball Mixed League

Co-Ed Slowpitch League
Season started 17/12/2018

The GLSML is the largest open slowpitch softball league in the country, with over 50 teams split over seven divisions. The divisions are split into Majors and Minors, with three divisions in Majors and four in Minors. The GLSML is the only Open League in the Greater London area, meaning that new teams are welcome irrespective of background or affiliation. We aim to strike a balance between fun and competition, by promoting a community ethos as well as offering training and development opportunities for players and umpires.

The GLSML season is typically 14 games long and runs from May to August. At the end of each season the top and bottom two teams in each division are promoted/relegated. (subject to change for lower Minors division due to new added division and teams.)

In addition to the league, the GLSML organises two Saturday tournaments during the season for league teams: Firstball early in the playing season, usually May or June and Lastball in August. Many of our teams also compete in the other tournaments that fill each summer. At the end of the season, the GLSML All-Star Day features players nominated by each team in a series of North London vs South London matches.

For new players, the GLSML offers Softball 101 (development) nights on Mondays in Regent's Park, where those interested to learn softball are taught the basics of the game. The intention is to create a new team to compete in the Lastball tournament in August and to enter the Minors the following year. This has proved a great way to introduce people to the game.
