While Serena Williams became the first player to secure one of the eight singles berths at the BNP Paribas WTA Finals Singapore presented by SC Global by virtue of her US Open performance, several others made noise on the Road To Singapore leaderboard with deep runs at the season's final Grand Slam.
Most notably, US Open runner-up Caroline Wozniacki went from No.15 before the US Open to No.9 after, which is just one spot outside the coveted Top 8. That's a far cry from where she stood after the clay court season, in 27th place, but a great summer has done wonders for her Singapore chances.
Semifinalist Ekaterina Makarova climbed from No.17 to No.11, quarterfinalist Flavia Pennetta ascended from No.16 to No.15 and semifinalist Peng Shuai vaulted from No.33 to No.20. And though she lost early at Flushing Meadows, Petra Kvitova still managed to improve a spot to No.5.
The only player in the Top 20 on the leaderboard in action this week is No.19 Venus Williams, who is competing in Québec City.
As for the doubles leaders, US Open champions Ekaterina Makarova and Elena Vesnina and runners-up Pennetta and Martina Hingis made major moves.
Makarova and Vesnina rose from No.6 to No.3 and Hingis and Penetta from No.38 all the way to No.12 and within four spots of the eighth and final qualifying spot. The Swiss-Italian duo plans to team up during the upcoming Asian swing, so a further improvement is possible.
