Roark, Ramos lead Nationals past Cubs 2-1

Wilson Ramos hit a tiebreaking homer in the sixth, Tanner Roark pitched five effective innings and the Washington Nationals beat the Chicago Cubs 2-1 on Monday.

Denard Span also homered for Washington, which has won eight of nine.

Making his first start of the season in place of the injured Doug Fister, Roark (1-2) allowed rookie Kris Bryant's sixth home run and struck out three. Four relievers combined for four innings of two-hit ball, with Drew Storen working the ninth for his NL-best 15th save in 16 attempts - closing out the five-hitter.
