Orioles manager Buck Showalter said Monday that Brian Roberts (hamstring) will play at least three minor league rehab games. Roberts is scheduled to begin his rehab stint Tuesday night with Triple-A Norfolk. The Orioles will likely want to see him play on back-to-back days before bringing him back, but it sounds like he could rejoin the Orioles before the end of the week if all goes well. The 35-year-old is currently making his way back from hamstring surgery.
