Top seed Ivanovic reaches Indian Wells semi-finals

　　INDIAN WELLS, California, March 20, 2008 - Top-seeded Serbian Ana Ivanovic booked her semi-final berth at the Pacific Life Open on Thursday with a straight-sets victory over Russian Vera Zvonareva.

　　Ivanovic, whose runner-up finish at the Australian Open propelled her to number two in the world rankings, took 66 minutes to complete a 6-1, 6-4 victory over the 21st-ranked Russian.

　　She blitzed through the first set, winning the first four games, and seized an early break in the second before surrendering her own serve for 2-2.

　　"In the second set I had a break up and lost concentration in that game," Ivanovic said. "I started to get a little bit emotional, trying to go for too much and lost my rhythm a little bit.

　　"I was just happy that at the end of the second set I managed to keep calm and play good," added the Serb, who broke again for a 5-4 lead and served out the match.

　　Despite her ascent in the rankings, Ivanovic is seeking her first WTA title since Luxembourg last September.

　　She is seeded first for just the second time in her WTA career. Last month, her first outing as top seed ended prematurely when she sprained her ankle in Doha and had to withdraw.

　　Ivanovic awaits the winner of Thursday afternoon's match between third-seeded Serbian Jelena Jankovic and US veteran Lindsay Davenport.

　　Davenport, 31 and enjoying a resurgence after taking nearly a year off to have a baby, has won this title twice, in 1997 and 2000. The former world number one is also a four-time runner-up, her most recent finals appearance coming in 2005.

　　Australian Open champion Maria Sharapova, the fourth seed, and second-seeded Svetlana Kuznetsova both won on Wednesday to book an all-Russian semi-final.
