SAN DIEGO -- Rockies rookie pitcher Drew Pomeranz's next scheduled start could be pushed back if the soreness that affected his work Friday night continues, manager Jim Tracy said Saturday afternoon. Pomeranz was ineffective for three innings of a 9-5 loss to the Padres and complained of general stiffness and discomfort in his arm afterward. Usually capable of a fastball 94-95 mph, Pomeranz sat at around 88. The Rockies have been using a four-man rotation in a paired pitching system since late June, but Pomeranz has yet to throw on three days' rest, like he would have to if he pitches Tuesday at Arizona on the team's normal schedule. Pomeranz was at Triple-A Colorado Springs when the system started and his four starts since returning to the Majors have happened to be on four days' rest. It's unknown how many days the Rockies would push back Pomeranz (1-5, 4.98 ERA) or who would take his place.
Pomeranz, 23, was icing his biceps Saturday and said he was still sore, but he hoped to throw a bullpen session Sunday.
