Novak Djokovic's wife Jelena came to see him play the opening match of his defense of the U.S. Open but she left early and looked glum throughout.

The Serbian beat Poland's Jerzy Janowicz 6-3, 5-7, 6-2, 6-1 but it was a labored performance that suggested he has not regained the form that made him the Number One player in the world rankings.

Djokovic had blamed 'private issues' for crashing out of Wimbledon to American Sam Querrey, who was seeded only 28th, in the third round of the tournament.
