"I'm very happy to have this trophy with me again," Nadal said. "It means a lot. It has been a fantastic week, a very positive one."Nadal later announced that he would skip a Masters tournament in Cincinnati this week to rest and get ready for the US Open.

"No other reason than personally taking care of my body and trying to keep as healthy as I feel now," Nadal said in a statement.

And so a "Big Four" reunion will have to wait for at least a few more weeks. Nadal, Roger Federer, Novak Djokovic and Andy Murray haven't played in the same tournament in more than a year. The other three are scheduled to play in Cincinnati this week.

Nadal's win Sunday was notable. His previous four titles this year came on clay at the French Open, Monte Carlo, Barcelona and Rome. He also beat Tsitsipas in in the Barcelona final.
