Orlando still perfect at home to go top; D.C. climbs high after big win in Atlanta
There's a new No. 1 ... though how long they stay there is anyone's guess. Elsewhere, Sporting Kansas City jumps into the top five coming off a dominant performance, while D.C. United gets the honor of making the biggest jump.
1. Orlando City SC (+1)
Sometimes winning when you're supposed to is the hardest part of becoming a top team. On Saturday against the Colorado Rapids, Orlando City showed they can handle the pressure by sealing a 2-0 victory. Now 5-0-0 at home, the Lions jump into the top spot.
2. FC Dallas (-1)
FC Dallas fought back from a one-goal deficit twice in a 2-2 draw with the Portland Timbers, but they drop in the rankings thanks to Orlando's win. Oscar Pareja's team conceded twice in a game for the first time all season.
3. Portland Timbers (no change)
Going on the road to Frisco and leaving with anything is a good result, but Portland will rue a chance missed to get another resume-building road victory. Sebastian Blanco's performance in the injured Diego Valeri's absence was excellent.
4. New York Red Bulls (no change)
The New York Red Bulls' renaissance continued with a 2-1 victory over the Chicago Fire at Red Bull Arena on Saturday, stretching the club's winning streak to three. Nevertheless, New York holds steady at four without a major slip-up in front of them to change their position.
5. Sporting Kansas City (+2)
Sporting's dominant defense is the hallmark of Peter Vermes' team, but goals are starting to come from a more ruthless transition, as evidenced by the 3-0 win over Real Salt Lake. That defensive record and the wins it's bringing help SKC move into the top five.
6. Toronto FC (no change)
TFC are getting big contributions from their biggest stars. Last week, Sebastian Giovinco fired home a pair of goals in an important win. This week, it was Jozy Altidore doing the deed with a brace in the 2-0 win against the Houston Dynamo. TFC stand pat after taking care of business at home.
7. Columbus Crew SC (-2)
There was some good in Crew SC's 3-2 defeat at the hands of New York City FC, but lax defending and an inability to hold on to a lead at home drops them out of the top five. They're now on a two-game losing streak, and there's reason to worry a bit in Ohio.
8. New York City FC (+2)
Patrick Vieira shook things up by benching Andrea Pirlo on the road, and it paid three points' worth of dividends in the win at MAPFRE Stadium. NYCFC jump two spots after the victory in Columbus. The question now is whether Vieira will stick with Yangel Herrera.
9. Seattle Sounders (-1)
The Sounders fought back from a three-goal deficit against the New England Revolution and deserve credit for their resolve in the 3-3 draw. Tying at home -- after going down by such a big margin -- doesn't make for positive movement in the Power Rankings, however.
10. D.C. United (+4)
Riding an excellent performance from Luciano Acosta built on a recognition of how to victimize Atlanta United's high press, D.C. got a 3-1 win in Georgia and is the biggest mover in this week's rankings.
11. Atlanta United (-2)
Atlanta lives by its energetic high press, and sometimes -- as on Sunday against D.C. -- they die by it. Despite dominating the possession stats, the expansion side couldn't stop D.C.'s counter and have fallen out of our top 10.
12. Houston Dynamo (-1)
Houston is just a different team on the road, and it showed again in Toronto. The Dynamo were undone by the clever passing of the Reds and their own lifeless attack, and drop a spot in the rankings because of their 2-0 defeat.
13. San Jose Earthquakes (no change)
The Quakes showed some life with a tight 1-0 win in Minnesota, but it's not enough to move them from their previous ranking. They'll have to show more to make any move, with goals still at a premium for Dom Kinnear's side.
14. Chicago Fire (-2)
The Fire started the Bastian Schweinsteiger era with two straight wins. Then they went on the road to Toronto and Red Bull Arena and dropped two in a row. That reality check drops them two spots with others winning behind them.
15. Vancouver Whitecaps (+3)
The Whitecaps were down a goal on the road and across the continent, then fought back for a massive 2-1 win over the Montreal Impact. Andrew Jacobson, Cristian Techera and Matias Laba were all excellent, powering Vancouver to jump three spots after their surprise victory.
16. New England Revolution (+1)
The Revs might have been the biggest movers of the week if they had been able to hang on in Seattle. Instead, leaving CenturyLink Field with a solitary point from a three-goal performance pushes them up a solitary spot in the rankings.
17. Montreal Impact (-2)
No home loss in MLS is ever good, but the Impact's 2-1 defeat to Vancouver is going to sting for a while. Montreal's attack was listless, in part because of Matteo Mancosu's injury, but the Impact drop two spots and into the bottom six regardless.
18. Real Salt Lake (-2)
Whatever bump RSL got from the arrival of manager Mike Petke is most decidedly gone. Getting thumped 3-0 in Kansas City has happened to better teams, and the Utahans were missing two key leaders. The loss still sees them drop a few places.
19. Minnesota United (no change)
Is Minnesota's defense getting better? Maybe, but that didn't help them on Saturday, when they couldn't find a way to score against the Earthquakes. If there's solace for the Loons, it's that despite their poor start, they're not last in the Western Conference.
20. LA Galaxy (no change)
Something seems fundamentally wrong at the StubHub Center. The Galaxy stay in the same spot after their scoreless draw with the Philadelphia Union, but that's largely because there's not much room below them.
21. Philadelphia Union (+1)
The Union are still bottom of the league, but at least they have company in that spot after earning a scrappy away point in Los Angeles. That jumps them up a spot, though there's still little reason to think big improvements are on the horizon. Philly still has no one to score goals.
22. Colorado Rapids (-1)
The Rapids went on the road to the toughest place to play so far in 2017 -- Orlando -- and lost. That wasn't exactly a surprise, but it is discouraging for Colorado that it went from a difficult team to beat in 2016 to a shell of its former self this season.
