Jelena Jankovic routed Caroline Wozniacki 6-3, 6-1 to reach the quarterfinals of the BNP Paribas Open, winning a matchup of former tournament champions and No. 1-ranked players.
Jankovic next plays either second-seeded Agnieszka Radwanska or 22nd-seeded Alize Cornet, who met later Tuesday in a fourth-round match.
Jankovic made the quarterfinals for the first time since winning the Indian Wells title in 2010, when she beat Wozniacki. The Dane won the title in 2011 and lost to Maria Sharapova in last year's final.
But she offered little resistance against Jankovic, who raced to a 5-0 lead in the second set before Wozniacki held at 40-love to avoid getting shut out.
