Lorenzo Cain capped a three-run ninth inning with a two-out single to left, bringing home Mike Moustakas and giving the Kansas City Royals a 7-6 victory over the Washington Nationals on Tuesday night.

Tanner Roark lasted into the eighth inning for Washington, but he was relieved by Felipe Rivero with runners on the corners and one out. Eric Hosmer grounded into a fielder’s choice to make it 6-4.

Rivero got through the rest of the inning and turned the lead over to Jonathan Papelbon (1-1), who served up back-to-back singles to start the ninth. After Omar Infante struck out, Moustakas came on to pinch hit and guided a single through the left side to knot the game 6-all.

Alcides Escobar kept the line moving with a single to center, and Cain ripped a liner into the gap in left-center.
