Orioles' Zach Eflin: Begins throwing progression

Eflin (lat) played catch Wednesday, Jacob Calvin Meyer of The Baltimore Sun reports.

Eflin began a throwing progression after being shut down with a mild right lat strain one week ago. The veteran right-hander is optimistic his absence won't last long, but a clearer picture of Eflin's timetable won't be available until he's further along in his throwing program.
