The Columbus Crew opened an eight-point lead atop Major League Soccer's Eastern Conference after a 3-0 win over the Houston Dynamo on Saturday in Columbus.
Venezuelan striker Emilio Renteria put Columbus ahead in the 34th minute, capitalizing on a blunder by Houston backup goalkeeper Tally Hall, who backpedaled as he tried to control the ball outside the penalty area and fell. Renteria seized on the loose ball and scored easily.
Houston, which has gone seven games without a win, saw its chances of a comeback reduced when defender Bobby Boswell was sent off for a second yellow with 18 minutes left.
Columbus capitalized on the extra man: English center back Andy Iro made it 2-0 in the 84th minute and French midfielder Leandre Griffit, two minutes into his MLS debut, added another in the 90th.
In Toronto, veteran Colombian striker Milton Rodriguez scored the 77th minute equalizer as Dallas earned a point at Toronto.
The goal, assisted by David Ferreira, came after Dallas gained a corner via Toronto's sloppy defensive play.
Brazilian forward Maicon Santos had put the hosts ahead in the 61st minute.
Though falling short of a victory that would have put the two teams level on points, Toronto maintained its unbeaten home record after nine games.
In Sandy, Utah, Real Salt Lake ran its franchise-record home unbeaten streak to 19 regular-season games by drawing with Chivas.
RSL has not lost at the Rio Tinto Stadium since May 16, 2009.
Midfielder Ned Grabavoy scored for Real Salt Lake with a stunning left-footed volley in the 67th minute. His goal came five minutes after replacing captain Kyle Beckerman, who returned after missing seven games with a torn foot tendon.
Mexican forward Jesus Padilla equalized for Chivas just three minutes later on a blast from the top of the box that Real goalkeeper Nick Rimando knocked down from chest level, only to have it bounce under him and into the net.
