The MLS Reserve League was a soccer league for the reserve teams of Major League Soccer with teams in both the United States and Canada.
It was inaugurated on April 9, 2005, with the first official reserve game being a 2–0 victory by Chivas USA over the host San Jose Earthquakes. The reserve division disbanded after the 2008 season but returned in 2011 with 18 clubs split into East, Central, and West divisions.[1] Each club played ten games consisting of home-and-away matches versus each of its five divisional opponents.
In 2013, the schedule of the MLS Reserve League was integrated with the schedule of the USL Pro, with teams from each league playing each other.[2]
In early 2013, MLS and USL reached an agreement to integrate the schedules of the Reserve League and USL Pro. Matches between teams of each league would be scheduled resulting in more games for all clubs.[2] MLS Reserve teams recorded 6 wins, 9 draws, and 11 losses against USL Pro teams in 2013.[3][4]
2014 was the final Reserve League season. Starting in 2015, MLS clubs must either affiliate with a USL Pro club or create their own team in the USL Pro. The LA Galaxy reserve team joined USL Pro as the LA Galaxy II in 2014 and finished third. MLS Reserve teams recorded 9 wins, 5 draws, and 14 losses against USL Pro teams in 2014.
Beginning in 2013, MLS teams could elect to affiliate with a USL Pro team rather than fielding an MLS Reserve League team.
In 2014, the number of MLS teams electing to affiliate with USL Pro teams (rather than fielding an MLS Reserve League team) increased and the LA Galaxy moved their reserve team to compete directly in the USL Pro league.
