Wei-Yin Chen (oblique) threw a bullpen session on Saturday. Chen has yet to be cleared for a rehab assignment, but hasn't had any setbacks since resuming a throwing program earlier this month.

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.

Wei-Yin Chen (oblique) threw from a distance of 120 feet Saturday. Chen continues to make progress in his throwing program and could be cleared for a bullpen session in the next 1-2 weeks. The 27-year-old right-hander has been sidelined since May 12 with a strained oblique.

There remains no timetable for Wei-Yin Chen's (oblique) return from the disabled list. It's been three weeks since Chen strained his right oblique, but he's yet to even throw on flat ground, having only jogged in a pool to this point.
