Roberts took swings off a batting tee and played catch with infield coach Juan Samuel for the second consecutive day prior to Sunday's game against the Indians, and manager Dave Trembley said the initial plan is for Roberts to head south on Wednesday.
Roberts played catch on Friday, but Saturday marked his first full day of activities, with Roberts fielding grounders for the first time since being placed on the 15-day disabled list.
The Orioles' leadoff hitter suffered a herniated disk in his lower back during offseason workouts in Arizona. Following 19 spring at-bats, Roberts was deemed ready to play, but reinjured himself on a slide into second base in the April 9 home opener. He was officially placed on the DL on April 12, retroactive to the date of the injury.
To clear a roster spot for Wednesday's addition of Corey Patterson, the Orioles moved Roberts to the 60-day DL, which would make him eligible to return as early as June 10. Prior to Friday's game, Roberts confirmed that his target date is the first day he's eligible off the DL.
