Rafael Nadal has decided to opt out of playing in next week's Miami Masters in order to rest after a busy return to the professional tour.

Nadal capped a successful start to his season with victory in the Indian Wells Masters after edging past Juan Martin del Potro in the final yesterday.

Miami organisers confirmed in a statement that the world number five would not be taking up an invitation to play at the Sony Open, which begins on Friday.

Tournament director Adam Barrett said: "We are disappointed to hear the news that Rafael Nadal will not be competing in Miami this year, especially given his strong results since his return to the tour.

"He is a tremendous ambassador for the game and has thousands of adoring fans here in South Florida. We wish him well and hope to see him back in Miami next year."

Nadal's victory at Indian Wells earned the Spaniard a record 22nd Masters crown and his 600th career win as a professional.
