Wisler's two-out RBI single capped the fourth inning, which was highlighted by the back-to-back homers A.J. Pierzynski and Juan Uribe hit off Doug Fister. But most of the 22-year-old right-hander's most valuable contributions came in the process of limiting the Nationals to one hit, while recording six strikeouts and issuing five walks over 5 1/3 innings.
The Nationals, who had won each of the past nine games played against the Braves, scored their run when Denard Span produced a two-out RBI single off Nick Masset in the seventh inning.
