Rangers pitcher Roy Oswalt has experienced discomfort while throwing for the first time since his last start was cut short because of a strained forearm.
Oswalt made his first start since Aug. 23 on Sunday, and the right-hander left after two innings because of flexor soreness near his elbow.
Texas said Thursday that the three-time All-Star will be evaluated in the next couple of days.
Oswalt joined the Rangers in late June. The 35-year-old is 4-3 with a 6.29 ERA in nine starts and four relief appearances.
