Ana Ivanovic is now one step away from defending her Indian Wells title, but she will have to overcome red-hot Vera Zvonareva.

The fourth-seeded Zvonareva reached the final by beating doubles partner Victoria Azarenka 6-3 6-3. The Russian didn’t drop serve once during the semifinal, and broke the eighth-seeded Azarenka a total of three times.

"It wasn't much of an experience. It was just a wasted match," Azarenka said. "I didn't play the game I needed to play. It was only unforced errors for me. Vera played well, but I didn't do even 10% of my game."

Despite the loss, Azarenka is projected to debut in the Top 10 when the new rankings are released on Monday.

Ivanovic, the fifth seed, put an end to Anastasia Pavlyuchenkova’s dream run, defeating the unseeded 17-year-old 6-2 6-3. Pavlyuchenkova scored her first two Top 10 wins at this year’s Indian Wells by upsetting Jelena Jankovic and Agnieszka Radwanska, but couldn’t get past the defending champion.

Defending champion Ana Ivanovic reached the semifinals of the BNP Paribas Open without playing, as her opponent Sybille Bammer withdrew before their match due to a left shoulder injury.

Serbian fifth seed Ivanovic will next meet Anastasia Pavlyuchenkova.  The Russian teenager upset seventh-seeded Agnieszka Radwanska of Poland 7-6(8) 6-4 in the quarters and reached her first Sony Ericsson WTA Tour semifinal. The world No.42 Pavlyuchenkova, who had eliminated second seed Jelena Jankovic in the second round, saved two set points down 6-5 and 7-6 in the tiebreak to take the all-important opening set.

Dinara Safina had a chance of overtaking Serena Williams’ No.1 ranking. Had Safina reached the finals at Indian Wells she would have climbed to the top of the rankings, but the Russian lost to Victoria Azarenka 6-7 6-1 6-3 in the quarterfinals.

Safina is aware that the ranking will come with improved game, and she believes the key is to return her aggressiveness on court.

I'm not thinking about this [the ranking] because if it comes, it comes. If I play like this, definitely it will not come. I played three rounds before and I was struggling with every player that I'm playing. With everyone I played, they were either serving for the set, or had set points. I have to finally start playing my game, because I'm not playing it. I just want for the next tournament (in Miami next week) to finally play my game and play like I've been playing like last year. Since Australia, I'm playing defensive, and it's not me. I just want to play aggressive.

Defending champion Ana Ivanovic beat Argentina's Gisela Dulko 6-3 6-3 to advance at the BNP Paribas Open.

The Serbian fifth seed didn’t score a too convincing victory, but was good enough to advance to the fourth round where she’ll face Italian 12th seed Flavia Pennetta.

"When it was very close on both sets I stepped up a little bit more and I just went for my shots and followed my instincts. I played really well," Ivanovic told reporters.

Ivanovic’s new coach, Craig Kardon, is definitely helping her game.

"I had lots of doubts about my game in the past six months," said the world No.7. "So finally I feel like I have strategy and also a plan in place again. It gives me a lot of security and confidence." (source: Reuters, photo: ivanovic-ana.com)

A reader suggested an interesting article from Los Angeles Times, which analyzes how much Serena and Venus Williams are compromising because of not entering the BNP Paribas Open, and also how much Maria Sharapova is missing for playing doubles only. Here we’ll focus on world No.1 Serena Williams only.

The annual prize money is increased from $63.6 to $84.4 million. The Top 10 players who participate in all four premier tournaments, one of which is the BNP Paribas Open in Indian Wells, will share a bonus pool, worth $1.9 million. Player with season-ending No.1 ranking will earn $400,000.

However, if you don't play in one of the four events, for whatever reason, you get no money and no ranking points. Plus, you will be fined for skipping the tournament unless you participate in a tour-mandated public relations event. Were Serena Williams to skip her makeup duty, she will be fined $75,000.

Here’s how LA Times sums it up mathematically:

If Serena finishes No. 1, her first loss would be the $400,000 from the bonus pool. If she decides to ignore the makeup appearance, that would be another $75,000. By not playing, she misses a chance at first-place money here of $700,000. Were she to team with Venus and win the doubles, that would be $118,500, her half of $237,000. That's $1,293,500.

Then, there are endorsements. One WTA official speculated that Serena's Nike contract, just as one example, "might have as much as two million dollars of incentive money for ending up No. 1." Winning at Indian Wells is worth 1,000 ranking points. Serena, who now leads No.2 Dinara Safina by 422, gets zero.

So, conceivably, Serena's rejection of Indian Wells could have cost her more than $3 million, or about 13% of her career tennis winnings of $23 million.

Well, it's great when you have so much money to lose. (photo: Ralf Reinecke)
