Adailton scored and the Chicago Fire won for the first time this season, 1-0 over the short-handed Philadelphia Union on Sunday.
Chicago (1-3-0) scored in the 37th minute when Adailton slipped the defense, deftly cut in front of goalkeeper Rais M'bolhi and flicked a header into the open goal off a set-piece from the left wing by Harrison Shipp.
Philadelphia (0-2-2) played the final 20 minutes down a man after Fred was shown a red card for throwing a punch at Shipp after a tackle at midfield. The Union were already missing four regulars for the game, with Cristian Maidana, C.J. Sapong and Conor Casey out with injury, and Zach Pfeffer sitting out a suspension.
Sean Johnson wasn't forced to make a save in the shutout. The Union managed just seven shots, none on goal.
Jordan Allen scored in the 89th minute and Real Salt Lake picked up its first win of the season, beating Toronto FC 2-1 on Sunday.
The 19-year-old's header from close range came off a feed from Javier Morales from the right wing.
It came just a minute after Toronto tied it at 1 when Jackson took a feed at the top of the box from Bright Dike and used a deft touch to sneak it past an outstretched Jeff Attinella.
Real Salt Lake (1-0-2) opened the scoring in the 38th minute, when Luke Mullholland got behind the defense inside the 6-yard box and headed home a long feed from Morales.
Both teams had apparent goals waived off. RSL lost one to an offsides call, and Toronto had one disallowed when Nick Hagglund was called for a foul.
Several players were away for both clubs with their national teams, including U.S. players Nick Rimando for RSL and Jozy Altidore and Michael Bradley for Toronto (1-2-0).
