World number one Rafael Nadal on Sunday withdrew from next week's ATP Cincinnati Masters event as he prepares for this month's US Open.

The 32-year-old scooped the 80th title of his career earlier Sunday with victory at the Toronto Masters. However the Spaniard said in a statement following the win that he had decided to adjust his schedule in order to preserve his fitness. "I am very sorry to announce that I won't be playing in Cincinnati this year," Nadal said.
