The Diamondbacks have a slightly better record, but have been mediocre at home, and in terrible form lately, but they had yesterday off and are playing the second straight series at home, while the Nats had to travel from Seattle last night.
The Dbacks seem to have the pitching advantage, as Kelly is looking sharp, while Irvin has been hit hard by Dbacks bats in the past, and already has a bad start against them this season. Add to the fact that the Dbacks hit better than the Nats, and the Nats have the second-worst bullpen in the MLB, so this is a perfect spot for Arizona to bounce back. Take the Arizona Diamondbacks on the runline.
