Having racked up 23 grand slam successes thanks in no small part to his relentless approach, a tired Novak Djokovic has withdrawn from the ATP’s National Bank Open in Toronto.

The world No.2 pulled out of the early August tournament on Sunday (local time), opting for additional rest after his loss just over a week ago to Carlos Alcaraz in the men’s singles final at Wimbledon.

Tennis Canada announced Djokovic had pulled out of the only Canadian stop on the ATP Tour schedule due to fatigue.

The 36-year-old was set to begin his hard-court preparations for late August’s US Open after falling to the top-ranked Alcaraz last Sunday in a thrilling five-set final at Wimbledon.

“I have always enjoyed my time in Canada but after speaking with my team, we believe this is the right decision,” Djokovic, who has won the National Bank Open four times, said.

“I really hope I can return to Canada and Toronto in the coming years to play in front of great fans there.”

American Christopher Eubanks will gain automatic entry into the main draw as Djokovic’s replacement.

Eubanks is fresh off a surprise quarter-final run at Wimbledon, where he beat No.5 seed Stefanos Tsitsipas and home favourite Cameron Norrie en route to the last eight.

“Of course, we’re disappointed that Novak won’t be playing at the National Bank Open this year,” tournament director Karl Hale said.

“He’s an incredible player and one we know our fans were eager to watch.

“He will be missed but we still have a long list of sensational players confirmed for this year’s event, including 41 of the top 42 players in the world.”
