The Diamondbacks get an early chance to return to regular 9-inning double headers, following the postponement of yesterday’s game in Washington. They’ll probably be a bit disappointed, considering they went 4-0 in 7-inning double headers, with three of those wins being shutouts, including the day against Atlanta where their pitchers allowed a total of one hit. One of the starting pitchers that day, Madison Bumgarner, takes the mound in the opener here, having no-hit the Braves the last time he started a double-header. Keep that up, MadBum. Also of note in the line-up. the first day off for Christian Walker, with Seth Beer starting at first, and Cooper Hummel at DH.
