Update: To take Johnson's place on the roster, the Orioles have called up outfielder Xavier Avery from Triple-A Norfolk. The Orioles made the move official, placing Johnson on the DL with a left oblique strain. Avery, 23, began the season with Double-A Bowie, where he batted .300/.391/.406 with 34 runs scored and 12 stolen bases in 39 games. He has also played in 15 games with Norfolk, batting .192 (10-52). The Orioles could option Avery if they activate reliever Pedro Strop over the weekend, or they could add another pitcher.
