Del Potro dishes out sage advice

WASHINGTON - Juan Martin Del Potro has some advice for 12-time Grand Slam champion Novak Djokovic as he prepares for a long break from tennis: stay home and play with the kids.

Del Potro, the 2009 US Open champion from Argentina who has endured long absences while battling wrist injuries, knows all too well the challenge Djokovic faces after announcing last week he will miss the remainder of the year with an elbow injury.

"It's not easy to stop for a long time and come back," Del Potro said. "Many players can play good after a long injury, but they won't play as good (soon after) as they will in the future.
