SANDY, Utah — Luis Silva scored twice to help 10-man Real Salt Lake beat the Colorado Rapids 4-1 on Saturday for the Rocky Mountain Cup.

Real Salt Lake (10-13-5) won its second straight game to move within a point of FC Dallas for the final playoff spot in the Western Conference. Colorado (6-15-4) lost the first game of the series 2-1 and will host the third match Oct. 15.

Joao Plata gave Real Salt Lake a 1-0 lead in the 41st minute with his seventh goal. He took three touches in space on the left side and beat Tim Howard to the near post. Silva sent Howard the wrong way on a penalty kick in the 50th minute to make it 2-0.

After Joshua Gatt pulled Colorado to 2-1 in the 82nd minute on a header that required a video replay, Silva and Brooks Lennon both scored stoppage-time goals.

RSL’s Danilo Acosta was given a straight red card in the 57th minute for a late challenge.
