Pena (thumb) took swings in the batting cage and was spotted fielding groundballs Tuesday, Brian McTaggart of MLB.com reports.

EDGE Analysis

In his most extensive workout since landing on the 10-day injured list six days ago due to left thumb injury, Pena looked to be taking part without any discomfort. He'll be eligible to come off the IL on Friday, but the Astros haven't said that he'll be cleared to play by then. More clarity on Pena's situation should become available within the next day or two.
