Collmenter has been scratched from his Saturday start and will be moved to the bullpen, Zach Buchanan of The Arizona Republic reports. Collmenter had looked at least solid in the games leading up to last Sunday's start, but that five-run outing must have been the last straw for Arizona before they decided to go with another, younger option. Collmenter's ERA and FIP both hover over five and he's given up a 1.7 HR/9, which is brutal at this point in the season. He'll be replaced in the rotation by new call-up Allen Webster.
