The season-ending Championships begin on Tuesday, November 6, and here’s what the order of play for the day one looks like:

From 18.00hrs (Madrid time, of course)

1. Justine Henin vs. Anna Chakvetadze
2. Maria Sharapova vs. Daniela Hantuchova (not before 20.00hrs)
3. Svetlana Kuznetsova vs. Ana Ivanovic

The 2007 Sony Ericsson Championships begins on Tuesday, and the round-robin draw has been announced today, so let's remind ourselves of the past champions of this tournament.

The draw for the 2007 Sony Ericsson Championships has been announced today in Madrid. There are two groups of four players, which play in a round-robin format. The leader of the yellow group is world number one Justine Henin, while Svetlana Kuznetsova leads the red group. Read more »

Venus Williams, originally in seventh place in the Race to the Sony Ericsson Championships points standing, has been forced to withdraw. Williams suffered dizziness during the US Open earlier this year and has been told by doctors not to play in the November 6-11 Madrid event.

As you know, only eight singles players can compete for a share of the $3-million prize purse at the world’s richest annual women's sporting event. Justine Henin, Jelena Jankovic, Svetlana Kuznetsova, Ana Ivanovic, Serena Williams and Anna Chakvetadze had qualified before. In my previous post I wrote that Maria Sharapova didn’t qualify because Daniela Hantuchova won the Generali Ladies Linz title, but now that Venus Williams has pulled out of the tournament, both the Russian and the Slovakian will play in Madrid.

This will be Sharapova’s fourth and Hantuchova’s second appearance in singles at the Sony Ericsson Championships. Sharapova was a champion at the event in 2004 and has been a semifinalist each of the last two years.

World number seven Anna Chakvetadze is the sixth player to qualify for the season-ending Championships, which will take place in Madrid, Spain from November 6-11. This great achievement was expected from the Russian taking into account her fantastic 2007 season in which she won four singles titles (Hobart, 's-Hertogenbosch, Cincinnati, Stanford).

“I’m so excited to play in my first Sony Ericsson Championships,” said Chakvetadze. “I love the beautiful city of Madrid and I’m hoping to perform very well. This has been an amazing year for me, having reached the Top 5 in the world, and I am looking forward to finishing strongly in Madrid.”

Two more players can qualify for the Sony Ericsson Championships and join Justine Henin, Jelena Jankovic, Svetlana Kuznetsova, Ana Ivanovic, Serena Williams, and Anna Chakvetadze. Those two players will probably be Venus Williams and Maria Sharapova. (photo via WTA Tour)
