Nationals' Tyler Clippard: Reinstated from injured list

Clippard (groin) was reinstated from the 15-day injured list Friday.

Clippard was sidelined for nearly a month due to a groin injury, but he spent the last week at Triple-A Rochester on a rehab assignment. Over three appearances with the minor-league club, he struck out four in four scoreless innings. Mason Thompson and Andres Machado were sent down to help make room for Clippard on the active roster.
