CINCINNATI (AP) Tanner Roark won the final spot in Washington's rotation during spring training. Halfway through the season, he's the Nationals' top winner.
Roark allowed only three singles over seven innings on Friday night, and Denard Span matched Cincinnati's hit total with his four singles, leading the Nationals to a 4-1 victory that extended their surge and the Reds' slump.
The Nationals won for the seventh time in nine games. They are 56-44, the second-best mark after 100 games in franchise history. The 2012 club went 60-40 on its way to the NL East title.
