Diamondbacks (29-33) at Padres (32-33)
Season series: Padres 2-1
Back in the pre-2012 days, when there was only one wild card spot available, both of these teams would already be considering who to trade at the deadline, as the Padres sit five games behind the Braves and the Diamondbacks 6.5 games back. However, with things the way they are, the Padres—even with their losing record—are in postseason position, holding the final wild card spot that the Diamondbacks put to such good use last season.
There are even a lot of similarities between the teams.
