Washington Nationals outfielder Jayson Werth was a late scratch for Sunday's series finale against the St. Louis Cardinals due to a hamstring problem.

Werth, who has already missed signficant time this season because of a broken wrist, left Saturday's 10-9 loss to the Cardinals in the ninth inning because of hamstring cramps.

Werth was set to lead off on Sunday, but was replaced at the top of the batting order by Roger Bernadina just prior to game time.

Since returning from the disabled list on Aug. 2, Werth is hitting .350 with a home run and 12 RBI.
