He has won four of six career meetings against Roddick, figures he's in for a difficult test in their semifinal. "He's playing very well. He started the season very well, semifinals in Australia. He played the final in Doha, too, and he won in Memphis," Nadal said. "It's going to be a really tough match."

Ivanovic, 21, dominated Pavlyuchenkova, a 17-year-old schoolgirl from Moscow who had upset No. 3 Jelena Jankovic and No. 10 Agnieszka Radwanska on the way to her first WTA semifinal. Pavlyuchenkova came in ranked No. 42.

"I was really happy with my performance," Ivanovic said. "She's not an easy opponent; she doesn't give you much rhythm."

The reigning French Open champion who held the No. 1 spot twice last year, seventh-ranked Ivanovic is going for her ninth tour title.

Zvonareva broke eighth-seeded Azarenka in the sixth game for the first set, and went up 2-0 in the second. The Russian saved all five break points she faced.

The 19-year-old Azarenka of Belarus lost for only the second time in 19 matches this year. Her run here, including a defeat of top-seeded Dinara Safina, will move her into the top 10 for the first time.

Zvonareva and Azarenka will be on the same side in the doubles final against Gisela Dulko and Shahar Peer. Lindsay Davenport was the last woman to win the Indian Wells singles and doubles titles, in 2000.
