Philadelphia Union maintained top spot in the Eastern Conference in the MLS, securing a 2-1 win away to Inter Miami on Wednesday.

Goals to Daniel Gazdag and Cory Burke handed the Union the three points to put them on 36 for the season, leading the Eastern Conference by a solitary point.

Gazdag's penalty in the 26th minute was critical, because from there the Union could absorb pressure, and the best defence in the MLS were able to grind out another win.

With only 35.7 per cent possession in the second half, their job was simpler after Burke doubled the margin in the 66th minute, heading in Kai Wagner's dead ball at the back post.

In only his second start since Inter's 3-1 loss to Houston Dynamo in April, Gonzalo Higuain bagged his third goal of the season – smashing the ball into the top corner from distance on the run, and on his opposite left foot – but it was mere consolation in the 82nd minute.

New York City remain hot on their heels, however, maintaining the one-point gap in the Eastern Conference after claiming a tough 1-0 win away to FC Dallas.

Heber was left with a simple tap-in in the 29th minute after Santiago Rodriguez was able to drive into space from the second ball, and he coolly finished for the eventual three points.

Elsewhere in the East, a Jhon Duran brace handed Chicago Fire a 2-0 victory over Toronto FC, while D.C. United twice equalised in the final 10 minutes to snatch a 2-2 draw at home to Columbus Crew.

Cincinnati and Orlando City dropped critical points in the playoff race with respective draws to the Vancouver Whitecaps and Colorado Rapids, while a Ronaldo Cisneros brace gave Atlanta United a big 2-1 win over Real Salt Lake, putting them three points behind seventh-placed Charlotte.

Most of the chasing pack in the Western Conference were not able to capitalise on Dallas and RSL's slip-ups, with Minnesota United playing out a 1-1 draw with Sporting KC, while the San Jose Earthquakes scored a 3-2 win away to Los Angeles Galaxy.

Nashville SC did capitalise and moved to third in the West though, claiming a 1-0 win at home to the in-form Seattle Sounders.

Hany Mukhtar scored the eventual winner in the 44th minute with the interval beckoning, scoring in transition after Randall Leal snatched the ball and released CJ Sapong.

New York City have extended their winning streak to four games and moved into top spot in the Eastern Conference after a 1-0 road win over Minnesota United on Saturday.

City defender Alexander Callens netted the game's only goal in the 29th minute, while goalkeeper Sean Johnson was outstanding for the visitors.

Callens powered in the winner with a bouncing header from Santiago Rodriguez's corner.

Minnesota almost equalised in the 90th minute but were thwarted by a spectacular double save by Johnson from Emanuel Reynoso and Robin Lod efforts.

City moved ahead of Philadelphia Union in the east, after they could only manage a 1-1 draw away to under-achieving New England Revolution.

The Revs, who won last season's Supporters' Shield, have rallied after a poor start to their campaign, going unbeaten in their past five, but have only collected 16 points from 13 games.

Gustavo Bou had put New England ahead from the penalty spot in the 75th minute, but Union levelled two minutes later after Omar Gonzalez's inexplicable error allowed Mikael Uhre to score.

Montreal, who are third in the east, got back on the winners' list with a hard-fought 4-3 victory over Cincinnati with a double from Rommel Quioto.

Luquinhas netted a brace as New York Red Bulls stayed in touch with the Eastern Conference's top three with a 4-1 home victory over struggling DC United.

In the Western Conference, LAFC remains four points clear at the top after Brian Rodriguez's 47th-minute winner clinched a 3-2 triumph over San Jose Earthquakes.

LAFC had raced to a 2-0 lead inside 13 minutes but San Jose equalised after two goals from in-form Jeremy Ebobisse, who has scored an equal-league high nine times this term.

Rodriguez, who got the assist for Ryan Hollingshead's 13th minute goal, scored when a loose ball arrived at his feet unmarked at the back post, firing past Earthquakes goalkeeper JT Marcinkowski.

Nashville ended the Colorado Rapids' remarkable 23-game unbeaten run at home with a 3-1 victory.

Charles Sapong netted in the eighth minute, before Hany Mukhtar's quickfire double had Nashville 3-0 up inside 18 minutes. The win moves Nashville up to fifth in the west.

Dallas came from behind to win 3-1 at Orlando City, Real Salt Lake won their third straight with a 3-0 victory over Houston Dynamo and Vancouver Whitecaps moved off bottom spot with a 1-0 triumph at Sporting KC.

Inter Miami extended their unbeaten run to four games with a 2-1 home win over Portland Timbers, Columbus Crew triumphed 2-1 over 10-man Atlanta United and Toronto won 3-2 over Chicago Fire after two late Pozuelo goals.

New York City FC moved to second spot in the Eastern Conference on Sunday, claiming a 1-0 victory at home to Chicago Fire.

Following a handball from Miguel Navarro, Heber scored the lone goal for City from the penalty spot to move the reigning MLS champions to 23 points.

It was only the 30-year-old's second goal this season, and despite City's dominance in possession with 61.8 per cent of the ball, they could not translate it to anything substantial in open play.

City have nevertheless won six of their last seven games in the MLS to recover from a slow start to the season, with only one win in their opening five.

Ronny Deila's side sit a point from Philadelphia Union at the top of the Eastern Conference following the Union's 2-0 win on the road over Portland Timbers in Sunday's final game.

Elsewhere in the East, CF Montreal and New York RB both dropped points, losing to Real Salt Lake and Inter Miami respectively.

Orlando City let a two-goal lead within the opening 25 minutes slip, meanwhile, going down to nine men and eventually playing out a 2-2 draw away to Austin FC.

Moussa Kalilou Djitte's equaliser in the 95th minute salvaged a point for Austin, who could not manage to retake top spot in the Western Conference from Los Angeles FC.

Los Angeles Galaxy lost their second in the three games, going down 3-0 to Houston Dynamo, while FC Dallas also lost to Minnesota United.

The Seattle Sounders' disappointing start to the MLS season continued on Sunday, losing 1-0 to Colorado Rapids, while the SJ Earthquakes and Sporting KC played out a 1-1 draw.

After two goals in the opening ten minutes, Daniel Rios provided an 85th-minute winner for Charlotte as they defeated the Vancouver Whitecaps 2-1.
