The Nationals are down 2-1 in the third inning against the Diamondbacks, but Ross Detwiler can't be blamed for all of it.
Adam Dunn's error in the second inning helped extend an inning where the Diamondbacks scored both of their runs, only one of which was earned. Detwiler did give up a pair of doubles and walked Stephen Drew, but Dunn's error exacerbated the problem.
But the Nationals have pulled within one on Adam Kennedy's third homer of the year. It's striking how much better Kennedy has been since Cristian Guzman was traded; he has a .940 OPS this month.
