Sebastian Giovinco was sent off as Toronto suffered yet another MLS loss, while the LA Galaxy's struggles continued Saturday.
Reigning MLS Cup champion Toronto was beaten for the sixth time in nine games this season, going down 3-2 to the New England Revolution.
New England made a dream start at Gillette Stadium as Cristian Penilla scored twice in the opening seven minutes.
Penilla finished clinically to open the scoring before netting from 25 yards to make it 2-0 after Toronto goalkeeper Alex Bono was caught off his line following a poor turnover.
After Teal Bunbury extended New England's lead a minute into the second half, an Antonio Delamea Mlinar own goal brought Toronto back into the game.
Giovinco scored an 89th-minute penalty for Toronto to give the side hope of earning a point, only for the Italian star to be sent off for making contact with Wilfried Zahibo's face as he rushed back to halfway.
Toronto is 10th in the Eastern Conference after the club's struggles this season, while New England sits sixth.
Also battling are the LA Galaxy, who slumped to their fourth straight loss with a 3-2 defeat at Dallas.
Roland Lamah's brace helped Dallas to the victory, with the home side holding on despite Reto Ziegler's red card.
Zlatan Ibrahimovic, who is now without a goal in four games, almost equalized late on, but his powerful free-kick smashed the post.
The goal's still shaking. #DALvLA https://t.co/l3mShaqqwa
