The Orioles have just announced that they have placed 2B Brian Roberts on the 15-day disabled list with a strained abdominal muscle, retroactive to April 10. Roberts was batting .143 (2-14) with one double when he injured himself sliding into second base Friday against the Toronto Blue Jays. To fill Roberts' roster spot, the Orioles recalled INF Justin Turner from Triple-A Norfolk. Turner appeared in 16 spring training games for the Orioles and batted .344 (11-32) with one home run and seven RBI. Turner also saw action in 12 games for Baltimore in 2009 after batting .300 (116-387) with two home runs and 43 RBI in 108 games at Norfolk.
