Wei-Yin Chen (oblique) had no issues throwing off a half-mound on Thursday. Chen will progress to a full-mound session Saturday, then join the Orioles on their roadtrip to continue workouts. Dan Connolly of the Baltimore Sun notes that Orioles pitching coach Rick Adair wants to see him throw at least once on the road before the team clears him for a rehab assignment, so it sounds like he's still a couple of weeks away.
