Arizona starters seem to have trouble staying healthy in Colorado. A day after Jon Duplantier was forced to make an early exit due to a tight hamstring, Zac Gallen joined him, leaving early due to stiffness/tightness in the back. Although, in Gallen’s case, exiting early due to minor discomfort might have been a blessing. Through 3 2⁄3 innings, the young up-and-coming star pitcher for the Diamondbacks gave up six runs, all of them earned.If he threw over the plate, the ball was pounded. If he didn’t the Rockies’ hitters showed enough patience to wait for their pitch.
