The Astros activated McCormick (hand) from the 10-day injured list Tuesday, Brian McTaggart of MLB.com reports.
McCormick has been sidelined since mid-September with a small fracture in his right hand, but he's progressed enough to be included on the team's wild-card roster. While an option to get some reps versus lefties, McCormick is not in the Game 1 lineup against southpaw Tarik Skubal.
