The Washington Nationals handed a 6-4 lead to veteran closer Jonathan Papelbon, but he blew his second save of the season as the Kansas City Royals rallied to tie it at 6-6 in the ninth and a walk-off single by Lorenzo Cain won it. 7-6 final. The Nationals four-game winning streak was snapped with the loss and it set up a rubber match between the Nats and the defending World Series champs tomorrow afternoon in Kauffman Stadium at 2:15 PM EDT.
