Jeremy Peña is eligible to return July 8, but didn't want to put a timetable on when he might come back from a fractured rib.

The Houston Astros will be without one of their top players for the foreseeable future. Shortstop Jeremy Peña has been placed on the 10-day injured list with a small fracture in one of his ribs on the left side, the Astros announced Monday. The team will make a corresponding roster move Tuesday, before their series opener with the Colorado Rockies.

Peña's rib fracture will sideline him for at least 10 days, derailing a prolific season that had him near stardom.
