Novak Djokovic defeated Alejandro Gonzalez 6-1, 3-6, 6-1 to end the Colombian's surprising run to the third round at the BNP Paribas Open on Tuesday.
Djokovic earned the only two breaks of the third set, including a seven-deuce game that he closed out with a clever backhand drop volley. Gonzalez had never won an ATP Tour-level match in six tries before Indian Wells.
"It took me a little bit to get used to it," Djokovic said. Djokovic next plays Marin Cilic of Croatia, who beat Tommy Robredo 6-4, 6-3.
Top-seeded woman Li Na defeated Aleksandra Wozniak of Canada 6-1, 6-4, setting up a quarterfinal against Dominika Cibulkova of Slovakia that will be a rematch of the Australian Open final.
Jelena Jankovic routed Caroline Wozniacki 6-3, 6-1 to reach the quarterfinals. Jankovic next plays either second-seeded Agnieszka Radwanska or 22nd-seeded Alize Cornet, who met late in a fourth-round match.
