Werth aggravated the groin muscle injury he sustained last month, but he said it wasn't as bad as the original occurrence and could play one game of Sunday's doubleheader, Mark Zuckerman of MASNsports.com reports.

EDGE Analysis

The Nationals likely will be careful with the soon-to-be 38-year-old, perhaps holding him out of both games of the Sunday twin bill against the Phillies. Werth went 1-for-4 with two walks and a run scored before leaving. His absence would probably pave way for extra work by Chris Heisey and perhaps Brian Goodwin.
