Roberts (herniated disk) returned to the lineup Monday night after sitting out Sunday. Samuel said he would likely hold the second baseman out of Tuesday night's game to give him a day off Rogers Centre's turf … Reliever Jim Johnson (right elbow inflammation) said his live 25-pitch batting practice session went well and he was able to knock off some rust. Johnson will throw one inning of a simulated game Thursday and then could go on a rehab assignment as early as next week … Second baseman LJ Hoes, 20, whom the Orioles selected in the third round of the 2008 draft, was promoted to Double-A Bowie after he hit .289 with two homers and 27 RBIs in 60 games for Single-A Frederick. It could be a short stay as Hoes is holding the roster spot of Joel Guzman, who is away from the team for three days for a personal matter … Triple-A Norfolk first baseman Michael Aubrey was named the International League Player of the Week after he hit .304 with five homers, 16 RBIs and five walks in seven games.
