Nadal's participation in the season-ending Tour finals hung in the balance when the Spaniard pulled out of the Paris Masters
Rewarding as it was for Rafael Nadal to become the only player to win the same Grand Slam 12 times by chalking up his dozen at last month's French Open, the Spaniard arrived at Wimbledon this year like a man on a mission.

Nadal is bidding for his second title in his 15th appearance at Melbourne Park
Rafael Nadal does not expect to return to play competitive tennis until 2021 due to the coronavirus pandemic, which has decimated much of this year's calendar. The World No 2 said he has practically written off the remainder of the year and is looking to the Australian Open in January 2021 as the next tournament he will play.
Rafael Nadal's decision to skip the US Open because of health concerns has added another twist to the intriguing three-way battle for the most career men's Grand Slam titles and, in many eyes, the title of Greatest Of All Time (GOAT). Had the 34-year-old Spaniard managed to retain the title he won in a five-set thriller against Daniil Medvedev last year, he would have joined Roger Federer at the top of the list with 20 titles. Instead, his decision has cleared the path for 33-year-old Novak Djokovic to edge to within one of Nadal's Grand Slam tally with a fourth title at Flushing Meadows and 18 in total.
The World No 1 told reporters on Friday that his strong performances this season -- including clinching yet another Roland Garros title in June -- have given him momentum heading into the fourth major of the year next week.

The 33-year-old said that he has not had enough time to practise sufficiently due to inflammation in his left wrist.
