Novak Djokovic withdrew Sunday from the National Bank Open, opting for additional rest after his loss to Carlos Alcaraz in the Wimbledon final. Tennis Canada announced that Djokovic pulled out of the only Canadian stop on the ATP Tour schedule due to fatigue. The 36-year-old, 23-time Grand Slam champion was set to begin his hard-court preparations for the U.S. Open after falling to the top-ranked Alcaraz last Sunday in a five-set final at Wimbledon.
