Tampa Bay Rays right-hander Taj Bradley was scratched from a scheduled start Tuesday against the Baltimore Orioles at Sarasota, Florida, and sent for an MRI after experiencing pectoral tightness while warming up.

The Rays were relying on the 22-year-old Bradley to win a job in the starting rotation.

Manager Kevin Cash said he's optimistic the injury to Bradley's right pectoral muscle was caught before it becomes serious, according to the Tampa Bay Times. Cash said he should know more Wednesday.

Bradley threw more than 50 pitches in his only start this spring training.
