Novak Djokovic has withdrawn from The Western & Southern Open in Cincinnati due to recurring left wrist injury, tournament officials announced Wednesday.
The tournament, which starts Aug. 13, is the only Masters 1000 tournament that Djokovic has not won.
The world No. 1 has stumbled over the past couple of months. After winning the Australian Open and French Open earlier this year, Djokovic was beaten in the third round of Wimbledon by American Sam Querrey in four sets.
This week, he was upset by Juan Martin del Potro, 7-6(4), 7-6(2), in the first round of the Olympic singles tournament and then lost the next day with teammate Nenad Zimonjic in a doubles match.
Djokovic, a 12-time Grand Slam champion, has been ranked No. 1 by the ATP for 110 straight weeks.
