Colorado Rockies pitcher Drew Pomeranz will have his next start be delayed by soreness in his throwing arm, according to Troy Renck of the Denver Post. It's unclear whether the present injury will require a trip to the disabled list, but he'll test his arm by playing catch tomorrow before a decision is made.
According to Renck, the Rockies will either replace Pomeranz with Carlos Torres or promote a pitcher from Triple-A to help out. Whoever gets the nod will start on Tuesday against the Arizona Diamondbacks, which is when Pomeranz was scheduled to pitch.
Torres, 29, hasn't started in Colorado this season, although he's spent his time with Triple-A Colorado Springs in the rotation. Over nine relief appearances with the Rockies this year, Torres has a 2.19 ERA with eight strikeouts and eight walks.
