Nadal has enjoyed a remarkable resurgence in 2017, sparked by reaching the final of the Australian Open in January before winning his first major title in three years at the French Open in May; his 10th success at Roland Garros.
World number one Rafael Nadal scored his 67th victory of the season and 345th at Masters 1000 level overall after a hard-fought battle against Pablo Cuevas, prevailing by 6-3 6-7 6-3 in two hours and 20 minutes.
Top seed Nadal, a victor of 16 Grand Slam titles, had his knee heavily strapped in a battling three-set win against Uruguay's Pablo Cuevas yesterday. "I'm very happy for everything", said Nadal, who this year won the French Open and the U.S. Open.
Nadal, 31, has become the oldest year-end No 1 and first year-end No 1 over the age of 30 since the ATP Rankings were established in 1973.
"It could be a fantastic moment for me, but it is still a really hard challenge to me", Del Potro said. "It means a lot". And, for [playing] long term I going to do the treatment that I believe is going to be more safe and more important to [help me] keep playing tennis for as long as possible.' The ATP Finals start on 12th November, and Nadal will need to make a decision within eight days. Then Nadal regrouped himself and took away the first set at 7-5 with a big forehand. He told the media that at some points during the match, he couldn't move.
He further said, "I'm going to do my treatment, do my best to be playing in London, but I can not talk about that now because (it) is a day that is tough enough for me to pull out from here".
Nadal says "the pain during the match (on Thursday) was too much".
Also, fourth-seeded Alexander Zverev lost to Robin Haase 3-6, 6-2, 6-2, and No. 9 John Isner beat Diego Schwartzman 7-6 (2), 6-7 (11), 6-3.
Isner, who lost last year's final to Murray, next plays either No. 6 Grigor Dimitrov or Richard Gasquet.
