The Bangkok International Softball League (BISL) is a non-profit, slo-pitch men’s softball league started over 16 years ago by expatriate Americans living in Bangkok. The league runs from January to May each year. Eight teams participate in the preseason "one-pitch" tournament, 24-game regular season schedule, and a season-ending tournament in May. The league has a rich and competitive history featuring over 150 athletes from Asian, North American and European countries.
