Matzek (personal) has been throwing bullpen sessions but still has no timetable for a return to game action, Nick Groke of the Denver Post reports.

EDGE Analysis

Matzek has been dealing with some performance anxiety issues, which kept him out of the majority of spring training. It's a good sign that he's been able to get some pitching in, though, which should make his transition back into game action a bit easier. He should slot into the rotation with Triple-A Albuquerque once he does return.
