Right-hander Jordan Zimmermann is on the hill against Phillies right-hander A.J. Burnett. Zimmermann is coming off a strong start in Miami where he allowed two runs on four hits in seven innings. That halted a brief two-start hiccup where Zimmermann had allowed four runs in consecutive outings for the first time all year. Burnett is 10-4 with a 3.37 ERA in 20 career games (19 starts) against the Nationals. But this season, he's 2-1 with a 5.03 ERA in three starts against them.
