There's a revolution at the bottom of the SBI MLS Power Rankings, in more ways than one.

The New England Revolution's fourth consecutive loss pits the club at No. 17, the lowest it's been all season. Other clubs near the bottom, namely Sporting Kansas City and Chicago, are on the way up after each secured four points this past week to make up some ground on the league leaders.

Two of those leaders, Los Angeles and Philadelphia, each let leads slip away but still manage to hold the top two places, respectively, in the rankings. Teams that helped themselves with wins this past week include San Jose and Houston, which come in at Nos. 8 and 9, respectively.

Here are this week's SBI MLS Power Rankings (as voted on by SBI staff):

SBI MLS POWER RANKINGS (WEEK 13)

1. (Last week – 1) LOS ANGELES GALAXY (8-2-7, 31 points)

Last week: Tied Toronto FC, 2-2, on Saturday.

This week: at Colorado, 9 p.m., Saturday.

Outlook: The Galaxy looked to have Toronto FC beaten through Juan Pablo Angel's stoppage time goal, but a late defensive breakdown cost the club two points in a hectic sequence at home. With that in the rear-view mirror, Bruce Arena's club must go into the home of the defending league champions in a key Western Confernence battle.

2. (T-3) PHILADELPHIA UNION (6-3-4, 22 points)

Last week: Tied Real Salt Lake, 1-1, on Saturday.

This week: at Vancouver, 10 p.m., Saturday.

Outlook: The Union failed to hold on to a lead at home against Real Salt Lake but maintained its unbeaten run at home, where it is 4-0-3 this season. Despite the tie, the Union is tied with the New York Red Bulls for first place in the Eastern Conference and has a game in hand as it ventures out west to face a Whitecaps team that hasn't won in 14 matches.

3. (5) NEW YORK RED BULLS (5-2-7, 22 points)

Last week: Beat New England, 2-1, on Friday.

This week: at Portland, 10 p.m., Sunday, Galavision.

Outlook: The Red Bulls finally got back in the win column after going almost six weeks without a victory, and Theirry Henry and Greg Sutton are the big reasons why. Henry scored and had a cross deflected in for an own goal, and Sutton stopped a Shalrie Joseph penalty to lift New York to a needed result. Whether the club can capitalize on its momentum and on Portland's recent struggles remains to be seen. The Red Bulls are just 1-1-4 away from Red Bull Arena this season.

4. (2) FC DALLAS (7-4-4, 25 points)

Last week: Lost to Sporting Kansas City, 4-1, on Sunday.

This week: at Chivas USA, 10:30 p.m., Saturday.

Outlook: And just like that, FC Dallas' nine-game unbeaten run is toast. The Red Stripes turned in the biggest head-scratcher of a result this past week, getting smoked at home by a troubled Sporting Kansas City side that was without Ryan Smith and Omar Bravo and had Teal Bunbury and Kei Kamara come off the bench. They'll head to the road to try and turn things back around.

5. (T-3) REAL SALT LAKE (6-3-3, 21 points)

Last week: Lost to Columbus, 2-1, on Wednesday; Tied Philadelphia, 1-1, on Saturday.

This week: vs. D.C. United, 9 p.m., Saturday.

Outlook: Real Salt Lake will be happy to return home after a two-game road swing that yielded a single point. Fabian Espindola and Jean Alexandre continued to show the ability to be an effective pairing, as the two combined for the equalizer in Philadelphia over the weekend.

6. (6) SEATTLE SOUNDERS (5-4-7, 22 points)

Last week: Tied Vancouver, 2-2, on Saturday.

This week: at Toronto FC, 7 p.m., Saturday.

Outlook: The Sounders emotional roller coaster of a night on Saturday ended in a draw after the club conceded a highlight-reel equalizer in an entertaining four-minute span. After Mauro Rosales and Osvaldo Alonso looked to have given Seattle a come-from-behind win, a defensive miscue yielded the only chance that Eric Hassli needed to level the score.

7. (7) COLORADO RAPIDS (5-3-7, 22 points)

Last week: Beat Portland, 1-0, on Saturday.

This week: vs. Los Angeles, 9 p.m., Saturday.

Outlook: Just when it looked like Colorado was headed for consecutive draw No. 7, Drew Moor stepped up to lift the Rapids to an impressive road result. Trailing the Galaxy by six points but with two games in hand, the Rapids will look for a repeat performance from last year's Western Conference playoffs to shrink the gap and get back in the mix atop the table.

8. (10) SAN JOSE EARTHQUAKES (5-4-4, 19 points)

Last week: Beat D.C. United, 4-2, on Saturday.

This week: at Sporting Kansas City, 8:30 p.m., Friday, Fox Soccer Channel.

Outlook: Without Chris Wondolowski and Ryan Johnson, the Earthquakes' offense has somehow been kicked into high gear. Steven Lenhart has taken the reins in San Jose, as his hat trick against D.C. showed how potent he can be when he's on his game. San Jose is now unbeaten in six games (4-0-2) following its three-match losing streak.

9. (12) HOUSTON DYNAMO (4-5-6, 18 points)

Last week: Beat Chivas USA, 2-1, on Saturday.

This week: vs. Columbus, 8:30 p.m., Saturday.

Outlook: The club's seven-game winless stretch is no more thanks to a crucial home victory. Brad Davis' Best XI campaign continues after his ninth assist and free kick set up both Houston goals against Chivas. If there's a winner between the Dynamo and Crew this weekend, that team will take sole possession of third place in the East. Both teams trail New York and Philadelphia by four points.

10. (8) CHIVAS USA (4-5-5, 17 points)

Last week: Lost to Houston, 2-1, on Saturday.

This week: vs. FC Dallas, 10:30 p.m., Saturday.

Outlook: The Goats got tripped up on the road, with a rare Heath Pearce own goal being the difference between a road point and a loss. Marcos Mondaini scored again for Chivas, though, and continues to show that he can be an offensive catalyst.

11. (9) D.C. UNITED (4-5-4, 16 points)

Last week: Lost to San Jose, 4-2, on Saturday.

This week: at Real Salt Lake, 9 p.m., Saturday.

Outlook: Just when it looked like D.C. was putting it all together, the club fell apart defensively at home, letting Lenhart run wild in its loss to the Earthquakes. Now United has to rebound and try and get a result at Rio Tinto Stadium, where the club is just 1-5-0 all-time. Rookie forward Blake Brettschneider continues to be a bright spot for Ben Olsen's club.

12. (11) PORTLAND TIMBERS (5-6-2, 17 points)

Last week: Lost to Colorado, 1-0, on Saturday.

This week: vs. New York, 10 p.m., Sunday, Galavision.

Outlook: The Timbers' home-field advantage isn't what it once was, as the club as dropped two straight at Jeld-Wen Field after starting the season 5-0 at home. Coach John Spencer was unhappy with the officiating in the loss to the Rapids, but he considered his team's effort in the match to be top-notch and will look for a repeat effort against the Red Bulls. Not having Futty Danso available for the next few weeks will test Portland's defensive depth.

13. (13) COLUMBUS CREW (4-4-6, 18 points)

Last week: Beat Real Salt Lake, 2-1, on Wednesday; Lost to Chicago, 1-0, on Sunday.

This week: at Houston, 8:30 p.m., Saturday.

Outlook: A giant step forward was met with a giant step back, as Columbus failed to put away Chicago at home in what could have been a landmark week for the club. Instead, more questions remain about the team's offensive inconsistency, and some in-fighting over Andres Mendoza's decision to take a penalty against RSL instead of giving way to Jeff Cunningham hasn't helped matters.

14. (15) CHICAGO FIRE (2-4-8, 14 points)

Last week: Tied Sporting Kansas City, 0-0, on Saturday; Beat Columbus, 1-0, on Sunday.

This week: at New England, 7:30 p.m., Saturday.

Outlook: With three consecutive shutouts, the Fire are starting to figure things out under Frank Klopas. The offense is still a work-in-progress though, as the Chicago attack has netted just one goal in those three clean sheets. The club was a bit fortunate to not concede a penalty to SKC in their midweek clash, and Cristian Nazarit's stoppage-time winner snapped the team's 11-game winless streak.

15. (16) TORONTO FC (2-5-8, 14 points)

Last week: Tied Los Angeles, 2-2, on Saturday.

This week: at New England, 8 p.m., Wednesday; vs. Seattle, 7:30 p.m., Saturday.

Outlook: Alan Gordon made himself right at home at the Home Depot Center. His last-gasp goal against his former team rescued a big point at Los Angeles for Toronto, which has been hanging tough in the standings due to its eight draws. The Reds have yielded the most goals in the league (25), though, and must tighten things up in the back moving forward.

16. (18) SPORTING KANSAS CITY (2-6-4, 10 points)

Last week: Tied Chicago, 0-0, on Thursday; Beat FC Dallas, 4-1 on Sunday.

This week: vs. San Jose, 8:30 p.m., Friday, Fox Soccer Channel.

Outlook: Many thought that SKC would get a win in Week 12, but few figured it would come at Dallas as opposed to in its home opener. The unlikely goal-scoring trio of Graham Zusi, Aurelien Collin and Luke Sassano helped SKC turn in one of the more unlikely results of the season and has the club headed in the right direction after a troubling start.

17. (14) NEW ENGLAND REVOLUTION (3-7-4, 13 points)

Last week: Lost to New York, 2-1, on Friday.

This week: vs. Toronto FC, 8 p.m., Wednesday; vs. Chicago, 7:30 p.m., Saturday.

Outlook: The Revs are in free-fall as losers of four straight matches. If the club was looking for a lift from its home fans this week, it might not be in luck, as its game against the Reds goes up directly against the Boston Bruins' Game 7 bout against Vancouver in the Stanley Cup finals. The club is missing Benny Feilhaber's influence and sorely needs a result to turn things around.

18. (17) VANCOUVER WHITECAPS (1-6-8, 11 points)

Last week: Tied Seattle, 2-2, on Saturday.

This week: vs. Philadelphia, 10 p.m., Saturday.

Outlook: Hassli's goal is the talk of the town, but it merely salvaged a single point after Vancouver carried a lead late into its match against Seattle but couldn't hold on. Vancouver still hasn't won since opening day and hasn't righted the ship just yet under new coach Tom Soehn.
