Roberts had started light baseball activities two weeks ago and on Saturday, took batting practice and fielded grounders at the team's Spring Training Complex in Sarasota, Fla.
Roberts has previously gotten this far in progressing back from the herniated disk in his lower back only to be set back, so it's likely the Orioles will use caution in easing him back into games. Roberts has been on the 60-day disabled list since the April 9 home opener, when he reaggravated the injury by sliding headfirst into second base. He told MASN's "The Scott Garceau Show" last week that he was targeting an Aug. 1 return and he hoped to get a full two months this season.
"Get on my feet again for 2010 and see if we can finish strong as a team," Roberts told the radio show. "And push toward this winter and next year."
Interim manager Juan Samuel told reporters on Sunday that Luke Scott (left hamstring strain) would also need a few rehab games, and Scott could get a few at-bats for the GCL Orioles. He was not listed as active on the affiliate's roster on Monday, but has been rehabbing in Sarasota and could get some live at-bats by the end of this week.
