Brian Roberts headed to Baltimore for tests

Orioles second baseman Brian Roberts has been plagued by a back injury for the last few weeks and his lack of progress has been frustrating for all parties involved.  So the O’s made a move Sunday, sending the 32-year-old back to Baltimore for an epidural and further examination of his ailing back.  Roberts is likely to begin the year on the 15-day disabled list and we can’t say for sure when he’ll be healthy enough for full-time action.  The nine-year vet hit .283/.356/.451 with 16 homers and 30 stolen bases in 632 at-bats last season.
