O's await results of Uehara's arthrogram

Trembley hoping to have righty back after All-Star break

BALTIMORE -- The Orioles took the next step with Koji Uehara's strained right elbow on Tuesday, subjecting the rookie to an arthrogram in order to ascertain the extent of the injury. Manager Dave Trembley said that Uehara hasn't aggravated the injury and that the test was more or less routine.

"Nothing happened," said Trembley. "What I was told is that the symptoms were still the same. The swelling and the inflammation had gone down, but from a precautionary standpoint, the next thing to do was to do this test and see what's going on. He hasn't picked up a ball, and he hasn't thrown or anything."

Uehara missed time with a tender hamstring earlier this season, and he pulled himself from his last start after six innings and 71 pitches. Trembley is hoping to have Uehara back right after the All-Star break, but the Orioles won't be sure of a timetable until they read the test results and get the right-hander back on a mound.

Uehara, a 10-year veteran of Japan's Central League, hasn't won since his first two starts of the season. Trembley has attempted to get him extra rest whenever possible, easing his transition from pitching once a week in Japan. Now Trembley knows that he has to be extra careful or risk losing Uehara for a longer period of time.

"This is the next step in a progression of evaluating his arm," said Trembley. "[Head athletic trainer] Richie Bancells will set him up with a physical therapist. He'll be on a program here in Baltimore."
