CHESTER, Pa. — Stefan Frei had six saves for his fifth shutout of the season, and the Seattle Sounders played to a scoreless draw with the Philadelphia Union on Saturday night.
Frei pushed Brenden Aaronson's shot to safety in the 18th minute and corralled the rebound of a low knuckler in the 53rd for the Sounders (7-1-5).
Andre Blake needed one save to register his second clean sheet of the year for the Union (7-3-3).
Both teams had winning streaks snapped by the result. Philadelphia had won three straight and Seattle was winners of its last two.
Cory Burke and Jamiro Monteiro each scored to help the Philadelphia beat the Montreal Impact 3-0 on Saturday for the Union's fourth win in their last five games.
Burke stole a lazy pass near midfield and then took a few dribbles before blasting a roller from outside the area just inside the far post to give Philadelphia (4-3-1) a 1-0 lead in the 14th minute.
Monteiro, a 25-year old on loan from FC Metz through June, converted from the spot in the 45th for his first MLS goal after Jack Elliott drew a foul conceded by Zakaria Diallo.
Alejandro Bedoya tapped in an empty-netter to cap the scoring 57th minute.
Montreal (3-3-2) had its three-game unbeaten streak snapped and conceded a goal for the first time since a 7-1 loss to Sporting Kansas City on March 30.
Philadelphia's Kai Wagner was shown a straight red card, after video review, in the 90th minute.
ATLANTA — Ezequiel Barco came on in the 67th minute and scored three minutes later to help Atlanta United tie the Philadelphia Union 1-1 on Sunday night.
Defending champion Atlanta used a series of quick passes to move to ball from the left to the right side where Julian Gressel first-timed a high entry and Barco side-netted a header inside the far post.
Brenden Aaronson, an 18-year-old homegrown making his MLS debut, ripped a right-footer that, as it went through the legs of Leandro Gonzalez Pirez, deflected off the defender's leg past goalkeeper Brad Guzan to give Philadelphia the lead in the 47th minute.
Atlanta had 71.4-percent possession — finishing with 669 passes compared to just 267 by the Union — but came up empty on a handful of chances. Josef Martinez, who set an MLS record with 31 goals last season, missed wide left on a shot early in the second half and later had his bicycle shot stopped by goalkeeper Andre Blake.
