To reach the quarterfinals of the China Open in Beijing Ana Ivanovic showed her mastery of consistent aggressive tennis and good focus against third-ranked Vera Zvonareva and scored her first Top 5 victory since June 2008 when she beat fellow Serb, then world No.3, Jelena Jankovic in the semifinals en route to the French Open title.

In the 6-2 6-1 win over Zvonareva, Ivanovic hit 29 winners to Zvonareva's four.

In the first round Ivanovic blew away Kimiko Date-Krumm 6-1 6-1, then powered past Svetlana Kuznetsova 6-2 6-3, and now she's in the the quarterfinals where she will face either Sofia Arvidsson, who upset Wimledon champion Petra Kvitova, or Agnieszka Radwanska, who won the Tokyo Premier tournament last week.

Just a week after eliminating the newly-crowned US Open champion Samantha Stosur in the second round of the Premier-level tournament in Tokyo, Maria Kirilenko repeated the feat by ousting the Australian from another high-profile event – the China Open in Beijing – also in the second round. However, in Tokyo it was Stosur's opener, while in Beijing she scored a 6-4 6-0 victory over Tsvetana Pironkova in her first match.

The unseeded Kirilenko advanced to the third round with a 7-5 1-6 7-5 victory over Stosur, after recollecting herself from a second set slump and a loss of six straight games. Next for Kirilenko is Tamira Paszek, who upset seed No.10 Jelena Jankovic in the first round.

Not even one 2011 Grand Slam champion is left in the China Open draw, even though it's still only the beginning of the tournament. French Open winner Li Na went out in the first round to Monica Niculescu 6-4 6-0, Wimbledon winner Petra Kvitova lost her opener to Sofia Arvisson 7-6(6) 4-6 6-3, while Australian Open champion Kim Clijsters hasn't even been playing since August.

Since her triumph at Roland Garros Li Na has been consistent with arranging  new sponsorship deals, but her tennis results are regularly disappointing. The Chinese has recently signed on with two more sponsors, Crown (Australia's leading integrated entertainment and resort operator) and Kunlunshan (China's first mineral water brand), but when it comes to tennis, she doesn’t know what to do to help herself.

The world No.5 Li followed her US Open first round exit with a defeat in her first match at the Beijing Premier-level tournament. Against qualifier Monica Niculescu of Romania, Li was bageled in the second set and in the first set won four games, only after coming back from a 5-1 deficit.

Right now I've just lost all confidence. On the court I don't know what I can do. I felt even winning one point was tough for me. My coach came out and told me exactly what was right, but I couldn't do it.

To make things worse, Li played the semifinals of Beijing last year, so she will lose a lot of points. Niculescu, ranked 58th in the world, scored her first Top 10 win. (via WTA Tour, photo: © Neal Trousdale)

Ana Ivanovic had to part ways with Heinz Gunthardt because his family and other obligations prevented him from being 100% dedicated to Ivanovic, while she needs a full-time coach – someone to accompany her at all tournaments and training periods.

Partnership with Gunthardt, which started in February 2010, brought improvements to Ivanovic's game. Their cooperation ended after the China Open.

Ivanovic will not have a coach by her side in Bali, but she claims to have no problem with that as she went all the way to the Generali Ladies Linz title without a coach. (source: AnaIvanovic.com, photo: © Neal Trousdale)

Never before had Caroline Wozniacki won a match at either the Tokyo or Beijing tournament, but this year the Dane won both in back-to-back weeks, earning the No.1 ranking on the way.

The final of the China Open in Beijing was postponed to Monday due to rain and top-seeded Wozniacki continued to consolidate her new top ranking by defeating the new No.3 and US Open and Wimbledon finalist Vera Zvonareva 6-3 3-6 6-3. One break in the beginning of the deciding set gave Wozniacki a 2-0 lead and she held her serve and didn’t even give Zvonareva break opportunities until the winner’s trophy was hers. The China Open title earned Wozniacki 1000 points, as well as $775,500, which means she’s earned more than a million in prize money in two weeks.

The 20-year-old Wozniacki doesn’t seem afraid of success: "Everything is working for me at the moment. I've got to believe I can beat anyone. I feel in great shape and now I'm really looking forward to Doha."

Wozniacki has now won six Sony Ericsson WTA Tour singles titles in 2010 and is the leader in the number of titles this season. Kim Clijsters follows her with four titles. Wozniacki is also leading other players in the number of matches won this season with 59. (source: Sony Ericsson WTA Tour)
