What is MPSL? The Monterey Peninsula Soccer League (MPSL) is a USSF affiliated adult amateur league that was founded in the early 1980's. While the MPSL is a men's league, women players are welcome and some of our teams usually have one or two female players. Most games are played on Sundays at Marina High School in Marina, California. Games are officiated under the FIFA Laws of the Game using a center referee and two assistant referees. Unlimited substitutions are allowed with the center referee's permission on dead balls. The level of play varies between Division 1 and Division 2 from year-to-year because of the annual turnover caused by the large number of graduate and undergraduate students that play in the MPSL. We have historically had teams from the Monterey Institute of International Studies, the Naval Postgraduate School, Monterey Peninsula College, the Presidio of Monterey and CSU Monterey Bay, along with a number of other local teams. The MPSL is affiliated with FIFA through the U.S. Soccer Federation, the U.S. Adult Soccer Association and the California Soccer Association North (CSAN). All players must be registered for the MPSL through CSAN.
