Well, if Roberts isn't ready, the O's seem prepared. They are looking at Todd Walker, former Sox (among others) 2B

The Baltimore Orioles continue to scout Cubs second baseman Todd Walker, who would be used as a designated hitter and left-handed bat off the bench. Walker also would serve as an insurance policy for second baseman Brian Roberts, who expects to get his first Grapefruit League action this week. Roberts is coming off elbow surgery and doesn't expect to be ready by Opening Day. A roadblock to a possible trade is the Orioles' reluctance to pick up all of Walker's $2.5 million contract.
