Ana Ivanovic's 14th WTA title and first on grass at the Aegon Classic lifted her two spots to No.6 on the Road To Singapore leaderboard.
With her biggest title since her 2008 French Open triumph, Ivanovic joined Maria Sharapova and Serena Williams as the only players with three WTA titles this season, having also been victorious in Auckland and Monterrey. The Serb, who was No.3 after the first week of the season and hasn't fallen outside of the Top 10, is now just over 300 points behind Williams for the fourth spot on the leaderboard.
Ivanovic's terrific year, which has also included a runner-up showing in Stuttgart and a semifinal outing in Rome, has seen her record a WTA-leading 37 match wins. And if her recent form continues, a spot in Singapore's field seems likely.
"It's something that really has been my motivation and inspiration for all these years," Ivanovic said. "I try not to think about it too much because during the hardcourt season in America, Indian Wells and Miami, I really put a little bit too much pressure on myself and I sort of lost sight of what was going on. It was so far away, yet I was thinking so much about it. So it's just about enjoying yourself and working hard, taking care of each match, and then the rankings and everything else takes care of itself."
The other movement in the Top 10 saw Dominika Cibulkova go from No.6 to No.7 and Eugenie Bouchard from No.7 to No.8, though with eight spots available at the BNP Paribas WTA Finals Singapore presented by SC Global, both players would still make the field if the draw was set today.
The Top 8 currently consists of Maria Sharapova, Li Na, Simona Halep, Serena Williams, Agnieszka Radwanska, Ivanovic, Cibulkova and Bouchard. Of those, Halep, Radwanska, Cibulkova, Bouchard, Jankovic and Errani are in action this week.
Two of Birmingham's quarterfinalists entered the Top 20, as Sloane Stephens went from No.24 to No.18 and Klara Koukalova went from No.25 to No.19.
Making a tremendous jump was Barbora Zahlavova Strycova, skyrocketing from No.70 to No.33 after making her first Premier-level final in Birmingham.
The Road To Singapore doubles leaderboard saw Birmingham champions Raquel Kops-Jones and Abigail Spears rise a spot to No.5. The Americans fell just short of qualifying for the season finale two years ago when they ended up in fifth place with four spots available, but this year eight spots are up for grabs.
