Jayson Werth scored the game-winning run on a wild pitch by Carlos Marmol in the bottom of the 10th inning to give the Nationals a 5-4 win over the Cubs on Monday afternoon. Werth along with Laynce Nix each plated two runs for Washington, which has alternated wins and losses in its last six contests. Henry Rodriguez tossed a 1-2-3 top of the 10th to register the victory. Marcos Mateo walked Werth before leaving and was saddled with the loss for Chicago. Alfonso Soriano drove in a pair, while Marlon Byrd and Geovany Soto each knocked in one for the Cubs, who have dropped three-of-four. Ramon Ortiz will be on the bump for Chicago, opposite Ross Detwiler in tonight's second installment from the nation's capital.
