Roberts -- currently rehabbing at the O's Minor League complex in Sarasota, Fla. -- is expected to get four at-bats as the team's designated hitter on Saturday before taking Sunday off. He will play seven innings at second base next Monday and follow that with another four at-bats as a DH. Roberts will get June 9 off and play his first full game at second base the following day.
Roberts is on the 60-day disabled list and eligible to be activated on June 9, although he won't be ready by then. Still, all reports out of Sarasota have been positive, and Trembley acknowledged prior to Tuesday's 3-1 loss to the Yankees in New York that Roberts might not be far off from June 9, with a return perhaps coming as early as mid-June.
Setup man Jim Johnson, out with right elbow inflammation, is scheduled to start a throwing program on Monday in Sarasota, while Felix Pie -- sidelined with an upper back strain -- will start throwing later this week. Trembley also said that reliever Alfredo Simon (left hamstring strain) is throwing and righty Koji Uehara (right forearm strain) is on a long-toss program.
