As a Diamondback, Greinke had already pitched four times against the Rockies including a July 5 seven-inning shutout effort. Opposite, Rockies pitcher German Marquez has regained his form with three-straight quality starts. Yet this total is a bit too low for as potent as both teams are at the plate. Grab the over (-101).
