Orioles' Grayson Rodriguez: Throwing on flat ground

Rodriguez (lat/elbow) has started throwing on flat ground but remains without a timetable for return, Roch Kubatko of MASNSports.com reported Wednesday.

Rodriguez has been on the injured list since spring training, though an April 23 diagnosis of a lat strain threw a wrench in his recovery from elbow inflammation. The 25-year-old isn't likely to rejoin the Orioles' rotation until the second half of the season, but the fact he's started up his throwing program is an encouraging development.
