CHICAGO -- Orioles minor league catcher Alex Murphy suffered an injury to his left shoulder over the weekend that likely will end his season at short-season Single-A Aberdeen.

Murphy, a Calvert Hall graduate, has been diagnosed with a left shoulder subluxation. He suffered the injury to his non-throwing shoulder while diving into second base on a pickoff play Friday. He left that game and hasn’t played since.

An MRI was performed on the shoulder this week, and player development director Brian Graham said it showed “some minor changes.” The MRI is still being evaluated by team doctors, Graham said.

Graham said the injury isn’t believed to be major, but it likely will keep Murphy from playing again this year. The IronBirds’ final game is Sept. 1 against Hudson Valley at Ripken Stadium.

Murphy, the Orioles’ sixth-round pick last season, was hitting .277 with three home runs and 25 RBIs in 54 games with Aberdeen this season. He also was 3-for-15 (.200) with one double and one RBI in four games for Low-A Delmarva earlier this year.

“He was really doing well,” Graham said. “Offensively, he was competing extremely well. His catching had improved. You’re talking about a 19-year-old player out of high school hitting in the middle of the lineup at Aberdeen.

“Aberdeen is usually a level for players out of college, and he’s hitting in the middle of the lineup there.”

NOTES: An MRI on Double-A Bowie left-hander Tim Berry’s throwing shoulder was clean, and the Orioles expect him to miss just one start with shoulder tendinitis. … Right-hander David Hess, the Orioles’ fifth-round pick in June out of Tennessee Tech, was promoted from Aberdeen to Delmarva. Hess, 21, was 2-1 with a 3.20 ERA in eight games (five starts) at Aberdeen. … Hess took the roster spot of left-hander Steven Brault, who was promoted to High-A Frederick. Brault, an 11th-round pick last season, was 9-8 with a 3.05 ERA in 22 games (21 starts) at Delmarva.
