CHESTER, Pennsylvania (AP) — Chris Pontius scored in the 78th minute to lift D.C. United to their fourth straight victory with a 1-0 win over the Philadelphia Union on Saturday night.
D.C. United moved four points ahead of the New York Red Bulls for first place in the Eastern Conference. It's their first four-game winning streak since the 2008 season.
The struggling Union haven't won in six outings since a 1-0 victory over Chivas USA on April 21.
A sellout crowd of 18,876 showed up at PPL Park for the debut of interim manager John Hackworth, who was promoted when Peter Nowak stepped down on Wednesday after two-plus seasons.
Hackworth was an assistant coach under Nowak since the Union's inception in 2010.
At Vancouver, British Columbia, Sebastien Le Toux's goal in the 80th-minute gave undermanned Vancouver victory over Colorado.
Vancouver won while playing a man down after striker Darren Mattocks was sent off in the 60th minute following his second yellow card.
The Whitecaps posted their seventh victory of the season, surpassing the six they mustered in their 2011 expansion season. Vancouver moved to 25 points, six clear of Colorado in the Western Conference standings.
Davide Chiumiento created the game's only goal after his clever dribble evaded three defenders and his cross found Le Toux's who's sliding volley beat Colorado keeper Matt Pickens.
At Houston, Adam Moffat scored his first goal of the season in the 76th minute to give Houston a 2-1 win over 10-man FC Dallas.
