Wins were hard to come by for teams at the top of ESPN's MLS Power Rankings, but the New York Red Bulls' impressive comeback from two goals down against D.C. United allowed them to remain unbeaten and claim the top spot...

1. New York Red Bulls (+1)

The Red Bulls stayed unbeaten with a spirited fight back from two goals down to tie D.C. United. With its next three games at home, New York is poised to create some early separation in the Eastern Conference.

2. D.C. United (+1)

Bill Hamid has for the most part smoothed out the rough edges in his game over the past two years. But he conceded a juicy rebound late that Lloyd Sam duly converted for an equalizer. For DCU, this draw definitely felt like two points dropped.

3. Real Salt Lake (+1)

No goals, no shots on target, yet another decent away result for RSL, who have yet to concede a goal on the road this season. Is it too early to worry about RSL's offensive struggles? Let's see what a run of three home games out of four yields.

4. Vancouver Whitecaps (-3)

A tough, tiring week that saw the Caps get just one point from two games ventured into brutal territory with the ejection of Pedro Morales late against San Jose. With the counter not working, Vancouver couldn't find a Plan B.

5. Sporting Kansas City (+2)

Whoever keeps sticking pins in the Ike Opara voodoo doll needs to stop. The luckless defender hobbled off injured again in Kansas City's 0-0 home draw against Real Salt Lake.

6. FC Dallas (-1)

Looks like defender Matt Hedges is even more important to Dallas' fortunes than originally thought. In his absence, FCD was simply overpowered by Colorado, with some weak defending the primary culprit. Is the annual late-spring swoon starting early?

7. Los Angeles Galaxy (+3)

The Galaxy owed their 1-0 victory over Seattle to goalkeeper Jaime Penedo -- who made 10 saves, some which he barely knew about -- and Alan Gordon, who scored on a trademark header. With Robbie Keane out injured, that's a result L.A. will gladly take.

8. Columbus Crew (no change)

The Crew managed to navigate their way through a difficult week by recording two respectable road draws at Vancouver and New England. The big concern at this point is the concussion symptoms plaguing Wil Trapp.

9. New England Revolution (no change)

The Revs welcomed Jermaine Jones back to the starting lineup, but amid gusty winds at Gillette Stadium, New England generated little in the way of offense. So far only Montreal is averaging fewer goals per game than New England.

10. San Jose Earthquakes (+4)

San Jose is still struggling to figure out how to accommodate Matias Perez-Garcia, but as long as the Quakes defend like they did in beating Vancouver, they'll always have a chance. San Jose is already halfway to last year's win total.

11. Seattle Sounders (-5)

The Sounders' 1-0 loss to L.A. was just the latest example of how a failure to take chances plus an inability to defend set pieces usually results in a loss. Lamar Neagle, who started up top in place of the injured Clint Dempsey, will be having nightmares about Penedo.

12. Chicago Fire (no change)

There are bye weeks, and then there is what Chicago is facing. With its April 18 game against Montreal rescheduled due to the Impact's CONCACAF Champions League commitments, the Fire will have a 20-day break between league games. Frank Yallop will hope his side doesn't accumulate too much rust.

13. Orlando City (+3)

The Lions conquered another Western Conference foe in beating Portland 2-0, and they may have solved their forward problems with Cyle Larin. Their record against the West is now 2-1 thanks to two road wins. Their record against the supposedly inferior Eastern Conference is 0-1-2. Go figure.

14. Houston Dynamo (+3)

Houston found an additional attacking element from a highly unlikely source, that being rookie Rob Lovejoy, who bagged a goal and an assist in a 3-0 win over Montreal.

15. Toronto FC (no change)

The MLS scheduling gods decided to give Toronto another bye week, the better to cope with its season-opening eight-game road trip. Given the injuries suffered by Toronto's backline, the time off figures to come in handy.

16. Colorado Rapids (+2)

The heretofore winless and scoreless Rapids broke out in a big way against Dallas, pinning a 4-0 road defeat on FCD. The power and movement of Dillon Powers was unstoppable.

17. Portland Timbers (-6)

So much for momentum. After dispatching previously unbeaten Dallas the previous week, the Timbers delivered a stinker against Orlando, in front of their home fans no less. Portland's attack continued its feast or famine ways, getting shut out for the third time in six games.

18. Philadelphia Union (+2)

Instead of falling victim to late-game magic, the Union created some of their own in beating New York for their first win of the season. Credit manager Jim Curtin as well for changing his mind on his choice of subs and leaving eventual goal scorer Vincent Nogueira in the game.

19. New York City FC (-6)

Slow starts continue to plague NYCFC, and when combined with a weak finish, it meant a 2-1 loss to previously winless Philadelphia. About the only good news is NYCFC gets another crack at the Union in midweek.

20. Montreal Impact (-1)

The Impact's exertions in the CONCACAF Champions League are clearly eroding the club's league form, with a 3-0 hammering at the hands of Houston just the latest setback. Perhaps the arrival of new forward Kenny Cooper can help on both fronts.
