DENVER -- Rockies left-hander Drew Pomeranz said delaying his next start from Wednesday to Sunday is merely a precaution, and the day will come when he proves he can pitch when not at his best.
The Rockies moved him to Sunday and called up righty Guillermo Moscoso to start against the Brewers on Wednesday because Pomeranz is dealing with soreness in a chest muscle. The problem affects his velocity.
"When I try to throw max effort, it bothers me," Pomeranz said. "I could go out there and pitch not at my best, back off a little bit, but what's the point? Might as well take a few days. Of course, it helps to keep my innings at whatever innings limit the have for me."
It's true the Rockies are being careful with Pomeranz, 23, who threw 118 1/3 combined innings in the Majors and Minors last year, his first pro season, and is at 111 1/3 combined between the Minors and Majors this year. But when announcing Pomeranz, 23, was scratched for Wednesday, manager Jim Tracy mentioned that Pomeranz will have to find a way to make it through an April-to-October season. At times, that means pitching through some issues.
At times, coaches and club officials have noticed Pomeranz checking the velocity readings on the scoreboard and seeming less confident when his velocity isn't right. They'd like for him to have the same demeanor and aggression no matter how he feels or what's working in a given game.
Pomeranz responded by saying he has done it before. He had a similar issue in college at Ole Miss, yet he pitched well enough that the Indians drafted him fifth overall in 2010.
"I strained my pec pretty bad, but when your team needs you to pitch, you've got to pitch, and find a way to win," he said.
Pomeranz insisted he has his confidence, despite a 1-7 record and 5.04 ERA in 13 starts. The team is 4-9 in his starts.
"I feel like I've pitched better than 1-7, but that's part of it," Pomeranz said. "As long as we're winning the games I've pitched, it doesn't matter."
The Rockies went to a four-man rotation in late June, but they've managed to avoid having Pomeranz pitch on three days' rest. They've scheduled him around off-days and pushed him back on occasion.
