Orioles pitcher Jason Hammel is expected to be activated from the disabled list Thursday but will be unavailable to pitch until Friday or Saturday, MLB.com reports.

Hammel deemed himself ready to return after his final rehab appearance Tuesday, and while he'd like to rejoin the rotation, it appears he'll pitch out of the bullpen initially. Hammel is 7-8 with a 5.20 ERA, 1.51 WHIP and 85:46 K:BB ratio in 123 innings over 21 starts.
