Joao Plata scored and assisted on goals by Javier Morales and Luis Gil to lead Real Salt Lake to a 4-2 win over the Portland Timbers on Friday night.
Alvaro Saborio added the other goal for RSL (14-8-6), which notched its second victory over Portland this month.
Darlington Nagbe and Sal Zizzo each scored for the Timbers (9-5-12), who played a man down the entire second half after Ben Zemanski was sent off with a red card just before halftime.
Portland had no answer for Salt Lake's precision passing early in the first half. RSL showed patience in working the ball into the attacking third and made the Timbers pay for it with a pair of early goals.
