SANDY, Utah -- Fanendo Adi scored a pair of goals and the Portland Timbers beat Real Salt Lake 3-1 Saturday night for their first victory at Rio Tinto Stadium.
Luke Mulholland scored for RSL, who are playing without team captain Kyle Beckerman and goalkeeper Nick Rimando while they are with the U.S. national team for the World Cup.
Timbers captain Will Johnson scored in the 73rd minute on a penalty kick he buried in the lower left corner.
Real Salt Lake (6-2-7) was coming off a midweek 1-1 draw at Columbus. RSL had its record-tying 12-match unbeaten streak to start the season stopped last weekend with a 4-0 loss to Seattle.
The Timbers (4-4-7) were coming off a 4-3 loss at home to the Cascadia rival Vancouver Whitecaps last weekend.
Mulholland took Chris Schuler's header and beat Portland goalkeeper Donovan Ricketts in the 23rd minute. Adi got the equalizer on a rebound in the 36th minute, then scored on a header in the 45th.
It was Adi's second brace this season. The Nigerian striker joined the Timbers last month on loan from Danish first-division side FC Copenhagen.
Real Salt Lake's Tony Beltran was sent off in the 54th minute after taking down Portland's Darlington Nagbe for his second yellow card, and Salt Lake played down a man for the rest of the match.
Real Salt Lake is 5-2-3 against Portland since the Timbers joined MLS in 2011. Last season, RSL beat Portland in the two-leg, goal-aggregate Western Conference championship to advance to the MLS Cup.
