Vera Zvonareva and Venus Williams have clinched the final two places in the season-ending WTA Championships in Doha from November 4-9.
Venus Williams will be making her third appearance in the season-ending event but first since 2002, having reached two semi-finals.
"I am really pleased to have qualified for this year's season-ending Sony Ericsson Championships in Doha,"
Williams said. "Competing in a round robin format with players who have performed the best in 2008 is an exciting challenge. This year has been a very positive year and I look forward to continued success in Doha."
Vera Zvonareva will appear for the second time but the first since 2004.
"It's really a great accomplishment that I have qualified for the Sony Ericsson Championships this year,"
Zvonareva said. "It has been a while since I last played there, and it feels wonderful to be one of the best eight players of the regular season. I look forward to returning to Doha to play the Championships, after I played really well at the Qatar Total Open earlier this year."
