Djokovic defeated Nadal at Indian Wells, Miami as well as last week at Madrid.

For Nadal, the Madrid loss came as somewhat as a surprise as the Spaniard had not lost a clay court match since 2009.

Djokovic has won 38 matches in a row and beat Nadal in Madrid in straight sets 7-5, 6-4 on Nadal’s favorite surface of clay. Nadal’s plan to attack the Serbian’s backhand in Madrid backfired as standing on or inside the baseline, Djokovic would unleash a number of key backhand winners.

Saturday the seventh seeded Sharapova used her aggressive groundstrokes to overpower the world number one Caroline Wozniacki of Denmark 7-5, 6-3 to advance to her second final of the year. Despite her top ranking, Wozniacki is yet to win a grand slam tournament.

Sharapova leads the sixth seeded Stosur head to head 7-0; lasting winning in the duo’s last meeting in Miami in March 6-4, 6-1.

However the two players have never faced each other on a clay court. Sharapova in recent months has mounted a spirited comeback from a reoccurring shoulder injury to rebound to a number eight ranking.

Stosur last year reached the final of the French Open, which begins this year in Paris May 22nd.
