Bradley Wright-Phillips moved a step closer to the MLS Golden Boot as New York Red Bulls pulled clear of New York City in the race for top spot in the Eastern Conference.
Wright-Phillips scored twice to lead the Red Bulls to a 3-2 victory over Columbus Crew on Sunday, taking his tally to 23 goals for the season.
The Englishman is one ahead of David Villa, whose New York City slumped to a 3-1 loss at DC United.
Despite Villa scoring a late penalty, New York City could not deny a rampant DC outfit the win and a play-off berth in the penultimate round of the season, leaving the former three points adrift of the Red Bulls.
Montreal Impact also booked their spot in the post-season following a 2-2 draw against third-placed Toronto, albeit with some help from New England Revolution.
Ignacio Piatti's brace had the Impact on track for all three points until Tosaint Ricketts' 86th-minute equaliser but the draw was still enough after the Revolution - who sit three points behind the sixth and final play-off spot in the east - lost 2-1 at Chicago Fire.
Philadelphia Union occupy the remaining post-season position, despite going down 2-0 to Orlando City.
