KANSAS CITY, Kan. — Diego Rubio scored two goals and Tim Melia had his 10th shutout of the season to help Sporting Kansas City beat the Portland Timbers 3-0 on Saturday night. Sporting (12-6-6) won its third straight to move into a tie atop the Western Conference standings with FC Dallas — which played Minnesota United later Saturday night. Rubio rifled a shot from the top of the box just inside the near post to open the scoring in the 28th minute and then made it 2-0 when he put away a cross by Daniel Salloi in the 37th. Johnny Russell capped the scoring in the 89th minute.
