SAN DIEGO -- Rockies left-hander Drew Pomeranz, who suffered left arm soreness during his start Friday night, most likely will have his start Tuesday at Arizona pushed back, manager Jim Tracy said. "I don't know that [a Tuesday start] is a possibility just yet," Tracy said. "He's going to play catch tomorrow in Arizona to determine the extent. Is it just a push-back or is it anything else?" The workload for Pomeranz (1-5, 4.98 ERA), who didn't debut as a professional until last season, yet appeared in the Majors at the end of last season, was a concern going into the year. The club intended to limit his workload this year. Although the current soreness was not anticipated, the team already was planning to monitor and at times curtail his innings.
Pomeranz has thrown 94 innings, including 43 1/3 in nine starts in the Majors. Pomeranz also has yet to throw on three days' rest, which is required in the team's current pitching system that uses four starters. Tuesday would have been his first time. It's unclear how the Rockies will fill the start. Tracy said they could call up a pitcher from the Minors or go to righty Carlos Torres (1-0, 2.19 ERA).
