Aryna Sabalenka paid tribute to "legend" Rafael Nadal, acknowledging the retiring Spaniard is "an inspiration to all of us".

The 22-time major winner announced on Thursday via a video on his social media platforms that he will retire from competitive tennis following next month's Davis Cup finals in Malaga.

Nadal's decision - generally expected given his injury struggles in recent years - has been met with widespread tributes throughout the tennis and sporting world.

And WTA number two Sabalenka - the reigning Australian and US Open champion - was the latest big name to salute the 14-time French Open winner, who was dubbed "the King of Clay".

"He's an inspiration for all of us, for the next generation, for current players. He's a legend," Sabalenka told WTA.

"As he said, everything has a beginning and an end. We are all going to be there. I'm really happy for what he was able to achieve. He was inspiration for everyone. He's a hard worker. He definitely had so much love for this sport."

Sabalenka is through to her 11th successive WTA quarter-final at the Wuhan Open after coming from behind to beat Yulia Putintseva 1-6 6-4 6-0.

The reigning champion recovered from losing the opening set - plus a break point at 4-3 down in the second set - to claim his 14th straight victory in Wuhan. 

"In the first set, I was all over the place," she added. "I'm really glad that I was able to put myself together in the second set and things clicked.

"In that game [the eighth in the second set], I was just trying to cool myself down and just to remind myself to keep trying, keep fighting.

"You have to work for it, you have to run, you have to play the point, build the point, find the right shot, then go for it, not rush things. I was just having that conversation in my head all the time.

"After that game, I felt like something clicked. The return was better. The movement was better. The decisions I was making were much better. I felt like that was really the turning point in the match."
