Those hoping to see injured Washington Nationals outfielder Jayson Werth begin his rehab assignment in Potomac on Friday night will have to wait, as the iffy weather is preventing him from getting back out on the field, according to Adam Kilgore of The Washington Post.

G. Richard Pfitzner Stadium, the home of the Class-A Potomac Nationals, is notorious for its poor drainage system, and with the rain on Friday, the MLB club may not want to risk putting Werth out there with the chance of getting injured again.

Werth has been out of the Nats lineup since May 6 when he broke his wrist while trying to make a sliding catch in right field. In 27 games in 2012, he is hitting .276 with 3 home runs and 12 RBIs.
