MLS Review: DC United wins goal-fest, Impact stuns Toronto

There were eight goals scored in DC United's win at home to the Chicago Fire, while Ignacio Piatti settled the "401 Derby."

Patrick Mullins scored a hat trick as DC United crushed the Chicago Fire 6-2, while the Montreal Impact earned bragging rights over rival and Eastern Conference leader Toronto FC in MLS on Saturday.

It was a goal-fest in Washington, D.C., with playoff chasing United finishing strongly to extend its unbeaten streak to six matches.

Luciano Acosta opened the scoring in the 25th minute but the Fire equalized six minutes later via Michael de Leeuw.

After Chicago's Khaly Thiam saw red in the 34th minute, a quick-fire brace from Mullins had DC 3-1 up with the interval fast approaching until Razvan Cocis pulled a goal back on the stroke of halftime.

And it was one-way traffic in the second half as Patrick Nyarko restored DC's two-goal advantage, Mullins completed his hat trick and substitute Nick DeLeon sealed the victory.

The rout helped sixth-placed DC improve to 32 points, four clear of Orlando City, while the Fire remains rooted to the foot of the table in the east.

Montreal recorded a 1-0 away win over high-flying Toronto, who was left licking its wounds.

Ignacio Piatti settled the '401 Derby' with 17 minutes remaining as the Impact snapped a 12-game winless streak in Toronto, despite Calum Mallace's red card and Didier Drogba's hamstring injury in a fiery clash.

Toronto, who was limited to just three shots on target throughout, lost reigning MVP Sebastian Giovinco to a leg injury midway through the second half.

The loss opens the door for New York City, who is two points adrift but can leapfrog Toronto if it beats Orlando City on Sunday.

Western Conference leader FC Dallas scored three unanswered goals in the second half to defeat Houston Dynamo, 3-1.

The Columbus Crew was 2-0 winners at home to San Jose Earthquakes, Philadelphia Union defeated Sporting Kansas City by the same scoreline, while LA Galaxy and Vancouver Whitecaps played out a goalless draw in a match which saw Steven Gerrard hobble off injured.
