Rafael Nadal called Tiger Woods an "amazing inspiration" after the Spaniard advanced to a 40th Grand Slam quarterfinal appearance, nine of which have come at the US Open.

"It means a lot to me to have him supporting. As I said, he's an amazing inspiration, all the things that he accomplishes in the sport, the way that he managed to keep fighting that hard," Nadal said.

"Watching him on the golf course, has been an example, a real inspiration for me. (To) have him supporting and be able to be in touch with him very often for me is something that I am super happy and I hope one day we can play golf and tennis together."

Tiger Woods made a successful return to top flight golf in 2018, winning the season-ending Tour Championship after missing most of the previous two years through a debilitating back injury.

In April, he won his 15th major after completing a memorable victory at the Masters, his first major win since the 2008 US Open.

"It's a big pleasure to have him here, he's one of the greats of sport and I want to congratulate him on one of the most amazing comebacks in sport, winning the Masters this year," Nadal said, suggesting his own golf game lagged far behind his ability with a racquet.

"It is much better if Tiger does not see my swing. Maybe he would lose a bit of rhythm after that."
