Novak Djokovic withdraws from Mutua Madrid Open

Needing more time to rest, Novak Djokovic has withdrawn from next week's Mutua Madrid Open.

The world's top-ranked player leads the ATP World Tour with 30 match wins (including 17 straight) and four titles. Djokovic is coming off a win at the Monte Carlo Masters, which included a thorough beating of Rafael Nadal in the semifinals.

Afterward, though, Djokovic said he was mentally drained and needed time to relax, enjoy his family and refuel before embarking on his quest to win the one major missing from this résumé.

Djokovic has been resolute in his mission to win the French Open this season. The Serb has lost to Nadal in each of the past three seasons at Roland Garros, including last year's final.

But considering their recent trajectories, Djokovic looks like the favorite heading into this year's clay-court major. Dating back to last year's Shanghai Masters, Djokovic has won six straight premier events, which includes the Masters 1000s, the ATP World Tour Final and the Australian Open. In that time, Nadal has won only one event, a small 250-level tournament in Buenos Aires in which he faced no player ranked higher than 160.

Djokovic is still scheduled to play the Internazionali BNL d'italia (Rome Masters), the final tuneup before the French Open.
