The gist » Despite sitting in second place in Group B, D.C. United (3-2-0) needs to achieve at least the same result against group-leading Toluca (4-1-0) that Marath?n (3-2-0) does against San Juan Jabloteh (0-5-0) in order to advance to next spring’s quarterfinals.
The rub » No U.S. team has ever won a meaningful match on Mexican soil. United has been shut out in each of its last three visits south of the border.
The real dilemma » By virtue of its 1-0 win over Columbus last weekend, United has kept its MLS playoff hopes alive until the final weekend of the regular season, forcing the team to again balance its travel roster against domestic ambitions. D.C. can make the playoffs with a win at Kansas City and a combination of other favorable results.
