Portland Timbers 1, Seattle Sounders 0

Even a few tense moments and a flurry of shots at the finish didn't dissuade Portland coach Caleb Porter from believing that the Timbers were going to beat the Sounders.

''We dodged some bullets, for sure,'' he said. ''But in the end I thought it was our game to win.''

Kalif Alhassan scored late in the first half and the Timbers held on to beat Cascadia Cup rival Seattle on Sunday night, denying the Sounders a chance to clinch a playoff berth.

The Timbers (13-5-14) moved into first place in the MLS Western Conference, pulling them closer to the postseason spot with two games left. Portland has not lost in six straight overall matches, and hasn't lost at home in 14 straight.

''Everybody is dialed in,'' midfielder Will Johnson said. ''Everyone is on board.''

It was the third straight loss for the Sounders, who fell to Vancouver Whitecaps 4-1 on Wednesday night. The Sounders (15-11-6) dropped into third place in the conference standings as the playoffs loom.

Seattle star Clint Dempsey, captain of the U.S. national team, appeared to injure his shoulder in the first half and twice went to the sidelines to seek treatment. But he returned for the second half.

He was trying his best, but he was carrying his shoulder,'' Seattle coach Sigi Schmid said. ''He couldn't go into challenges and tackles, he couldn't run normally. All those things affected him.''

With the Seattle loss, Vancouver claimed the supporters-created Cascadia Cup, an annual three-way competition between the Sounders, Whitecaps and Timbers.

Montreal Impact 0, New England Revolution 1

Jose Goncalves scored in the 31st minute and the New England Revolution kept their MLS playoff hopes alive with a 1-0 victory over the Impact on Saturday that extended Montreal's winless streak to five games.

The Revolution (12-11-9) stretched their unbeaten string to four games and moved within a point of the Impact (13-11-7), Philadelphia and Chicago for fourth place in the Eastern Conference. The top five teams in each conference advance to the playoffs.

The win, however, was tempered by the loss of forward Saer Sene to a broken leg.

Sene was taken off on a stretcher after getting injured in the 19th minute when his foot got caught between Davy Arnaud's legs while going for a ball in the Montreal penalty area.

The Revolution announced Sene's status on Twitter after the game, saying he dislocated his left ankle and broke his left fibula.

The crowd of 18,917 went silent when Sene went down and lay on the pitch in agony with his foot pointing the wrong way.

''I feel really bad about what happened,'' Arnaud said. ''It looks like it's a really bad injury. I think it was a good tackle. I won the ball clean, but his foot might have got caught underneath me. You never want to see that happen. I still feel bad about it. I hope he's OK.''

No foul was called as Arnaud got to the ball first.

''You run into situations on the field that are bigger than the game,'' Revolution coach Jay Heaps said. ''Everyone's heart went out to him.

''It's devastating for both teams. But the response from our guys - you just felt there would be a moment when our guys had a chance to make a play. We got that goal almost 10 minutes after that incident, so I was really happy with that.''

Juan Agudelo just missed heading in a free kick, but New England got the ball back for Diego Fagundez to slip it across the area for Goncalves to score his second of the season.

New England's defense did the rest as it clogged up the middle of the field and didn't allow league scoring co-leader Marco Di Vaio and his Impact teammates many good looks at the goal.

D.C. United 1, Philadelphia Union 1

Substitute Jack McInerney scored in the 90th minute to lift Philadelphia into a draw with D.C. United on Saturday night and boost the Union's playoff hopes.

Nick DeLeon scored in the 36th minute for United (3-23-6), which had ample opportunities to build on its lead but went its 10th straight match without a victory.

The Union (12-10-10) are tied with Montreal and Chicago for fourth place in the Eastern Conference on 46 points, with the top five teams advancing to the playoffs.

The New England Revolution lurk one point behind.

McInerney scored his first goal since June 1 on a clear header from inside the 6-yard box after reaching Kleberson's cross from the left.

The 21-year-old celebrated his team-leading 11th goal by stripping his shirt and racing toward a boisterous section of Union fans tucked under RFK Stadium's upper deck.

The goal came after United missed several chances to close the game out, the most notable coming just several minutes before when goalkeeper Zac MacMath streaked out of his goal but lost a foot race to United's Conor Doyle.

Doyle found Chris Pontius in the middle of the penalty area with MacMath still stranded, but Pontius' shot well high.

DeLeon scored his second goal of the season on a swerving strike from 30 yards after reaching Lewis Neal's pass from deeper in midfield. With space around him, DeLeon took three touches before unleashing a vicious shot that gave MacMath little chance.

Philadelphia's Sebastien Le Toux left the match in the 16th minute after apparently re-aggravating a foot injury.

FC Dallas 2, Chicago Fire 3

Call it a case of being in the right place at the right time.

Chicago striker Mike Magee tied for the MLS goal-scoring lead Saturday night by scoring his 19th goal when Alex's shot deflected off Magee's ribs and into the goal in the Fire's 3-2 win over FC Dallas on Saturday night.

Magee, who also had an assist, called it the ''the strangest goal I've ever scored.''

A loose ball went to Alex about 20 yards in front. His left-footed shot struck Magee, redirecting the ball on a bounce past goalkeeper Chris Seitz to give Magee his 13th goal in 19 matches for Chicago since being traded from the Los Angeles Galaxy.

''I wasn't even surprised because I didn't see anything,'' Magee said. ''I was trying to protect myself. And then it hit me in the rib cage.''

Magee is tied with Montreal's Marco Di Vaio for the scoring lead.

The victory moved the Fire (13-12-7) into a three-way tie with Montreal and Philadelphia for fourth place in the Eastern Conference with two matches remaining.

The top five teams in each conference qualify for the playoffs. New England is one point behind the three teams tied for the last two spots.

''There's still hope,'' Fire head coach Frank Klopas said. ''We want to be playing for something.''

Dallas (10-11-11) rallied from a 3-0 deficit on Kenny Cooper's two second-half goals, but was eliminated from playoff contention. Head coach Schellas Hyndman's team can reach no more than 47 points. Five Western Conference teams have 48 or more.

Hyndman said, ''We had a couple of good chances to tie the game, but in reality, it's a disappointing ending for us.''

Chicago opened the scoring in the 25th minute when Magee sent a corner kick from the left side to about 10 yards in front of the goal and Juan Luis Anangono headed it in.

The Fire took what looked like an insurmountable lead at 3-0 in the 52nd minute when defender Jalil Anibaba scored his first goal since May of 2012. His shot from 25 yards out hooked just inside the right post as Seitz tried to move over for a save.

''We're after our defenders all the time about shooting,'' Klopas said. ''But he takes a touch and puts it in the corner where it's almost impossible for the goalie to make a save. When that happens, it's OK for him to shoot.''

In the 63rd minute, FC Dallas' David Ferreira sent the ball in front of the net, where Cooper battled a defender and shot off the side of his right foot into the right corner. Cooper, who entered in the 12th minute when Mauro Diaz left with a leg injury, added his second goal on a penalty kick in the 75th minute. Fire goalie Sean Johnson went right, and Cooper shot to his left.

Johnson made three saves, all on shots by Fabian Castillo.

''We just shot ourselves in the foot again, just having to dig ourselves out of a hole,'' Dallas midfielder Andrew Jacobson said. ''They came out and they pressed us. We couldn't deal with the pressure.''
