Right-hander Joakim Soria has suffered a strained right pectoral muscle while rehabbing from Tommy John surgery, and his Rangers debut will likely be on hold July 1.
Soria was throwing live batting practice at extended spring training when he had to stop because of discomfort. An MRI showed a minor strain, and he won't throw for two or three weeks.
The Rangers had tentatively planned for him to return in late May or early June.
"It's completely unrelated to the arm," general manager Jon Daniels said. "It's one of those freak deals."
Left-hander Martin Perez, the victim of another freak injury when he suffered a broken forearm in spring training after being hit by a line drive, could start a rehab assignment next week. He will throw live batting practice today and pitch in an extended-spring game Saturday.
Colby Lewis is at least a week behind Perez. Lewis, coming back from a July operation to fix a torn flexor tendon, will throw live BP twice this week and work an extended-spring game next week. The Rangers continue to target late May for Lewis.
