World No. 1, Caroline Wozniacki of Denmark, had an easy time reaching the 4th round of the 2011 WTA BNP Paribas Open at Indian Wells with a win over Maria Jose Martinez Sanchez of Spain, 6-1, 6-3.
Martinez Sanchez was 3-0 against Wozniacki in previous matches, but this time, Wozniacki was the more consistent player and the outcome was reversed from their previous three meetings.
Martinez Sanchez got only 28 percent of her first serves in during the first set. Wozniacki took advantage, going on offense as soon as the second serves arrived. Her returns left the Spaniard scrambling during many points.
Wozniacki will now face No. 22 seed, Alisa Kleybanova of Russia. Wozniacki leads their career head-to-head series 2-0, winning their last meeting 6-3, 6-2.
