Brian Roberts has been placed on the 15-day disabled list with a strained abdominal muscle, the Orioles announced Monday.
The move, which was retroactive to April 10, comes three days after Roberts injured himself sliding into second base on a steal in Friday's 7-6 loss to the Toronto Blue Jays. Roberts was hitting .143 ( 2-for-14) with one double.
Replacing Roberts on the Orioles' active roster is infielder Justin Turner, who was called up from Triple-A Norfolk. Turner hit .344 (11-for-32) in 16 spring training games with the Orioles. He also hit one home run and seven RBIs.
Turner appeared in 12 games with the Orioles last season. He batted .300 (116-for-387) with two home runs and 43 RBIs in 108 games for Norfolk in 2009.
