"What that means, there's no description to it, but he just added very light [baseball activities]," Samuel said Saturday. "That's what my report says."
Roberts had been resting from the third epidural injection in his lower back, and the second baseman told Samuel on June 15 that he was four to six weeks away from returning, with the exact time frame dictated by when he returned to baseball-related activities.
Roberts has been on the 60-day disabled list (herniated disc in his lower back) since April 10, and at this point he isn't expected back until August at the earliest.
Although Roberts hasn't played in a game since the home opener on April 9, the Orioles second baseman has remained steadfast in his belief that he will see the field at some point this season. He has said previously that he has not considered having season-ending surgery.
