McCullers (forearm) could be ready to throw as soon as next week, Brian McTaggart of MLB.com reports.
McCullers remains shut down with a forearm issue that dates back to last year's postseason. The fact that he's on the 10-day injured list rather than the 60-day injured list may indicate that the Astros expect him back before the end of May, though an exact timetable has not yet been provided by the team.
