Nats Nightly

Tanner Roark gave up just one run in seven innings, but the Washington Nationals' bullpen made it interesting again as Jonathan Papelbon gave up a one-out single and a walk and a run scored before Oliver Perez and Shawn Kelley combined to shut the San Francisco Giants' rally down in what ended up a 4-2 win. Roark got the curly-W (10-6) and the Nationals improved to 60-42 on the year with three more to play in AT&T Park this weekend.
