The MLS Reserve League has been reformatted after returning this season from a two-year hiatus, along with a corresponding roster size increase from 24 to 30 players. Each team now only travels regionally for its training matches. Here is the league's press release on the reserve league's return, which begins Sunday with D.C. United and Columbus' opening tilt.
There are three regional groups, with six teams comprising each. The East is composed of D.C. United, Columbus Crew, New England Revolution, Toronto FC, New York Red Bulls and Philadelphia Union. The Central is composed of Real Salt Lake, FC Dallas, Colorado Rapids, Sporting Kansas City, Houston Dynamo and the Chicago Fire. The West is composed of Vancouver Whitecaps FC, Seattle Sounders FC, Portland Timbers, San Jose Earthquakes, Chivas USA and Los Angeles Galaxy.
Jeld-Wen Field is listed as Portland's home field for each of its five home games (one against each of the other teams in the division).
It should be interesting to see how much support the reserve matches will generate, especially because the first home match is against Seattle's reserve on May 30.
Below the jump is Portland's 10-game reserve league schedule in its entirety.
