Sporting Kansas moved to the top of the MLS Eastern Conference despite being reduced to ten men after they claimed a 2-1 win over the Columbus Crew.
C.J. Sapong scored the opening goal for Kansas in the 43rd minute before defender Aurelien Collin was sent off in the 55th. Columbus drew level through Igor Juliao's 69th-minute own goal but Benny Feilhaber (90) smashed a last gasp win for Sporting off the underside of the bar, a minute after Crew's Wil Trapp had been sent off for his second bookable offence.
The Los Angeles Galaxy eased to a 5-1 win over the New England Revolution to cut the gap on second place Real Salt Lake to one point in the Eastern conference. Both sides finished the game with ten men after A.J. Soares was sent off for Revolution in the 29th minute and Galaxy's Dan Gargan departed seven minutes later.
Robbie Keane (10, 78) scored the first and last goals for Galaxy - the opener being a superb, curling, long-range effort, with Gyasi Zardes (18, 48) and Stefan Ishizaki (75) also on the scoresheet, with Lee Nguyen's 38th-minute penalty scant consolation for Revolution.
Elsewhere, the Philadelphia Union defeated the New York Red Bulls 3-1 thanks to goals from Conor Casey (nine), Fred Carreiro (51) and Sebastien Le Toux's 69th-minute penalty. Bradley Wright-Phillips scored New York's only goal in the 60th minute.
