Brian Roberts (knee, hamstring) said Monday that he's getting closer to going out on a minor league rehab assignment. Roberts hasn't played since April 5 and required hamstring surgery last month. He'll need to run without restrictions before returning to game action, but it's not clear when that will happen. While the 35-year-old said last week that it was "definitely realistic" to expect him to return before the All-Star break, fantasy owners shouldn't count on him.
