Kveta Peschke and Katarina Srebotnik were one team to fall victims of the upset bug, losing out to Bethanie Mattek-Sands and Andrea Petkovic in the second round. While their wait to secure a place in Singapore continues, they remain in pole position to join the first five qualifiers - Sara Errani and Roberta Vinci, Hsieh Su-Wei and Peng Shuai, Ekaterina Makarova and Elena Vesnina, Cara Black and Sania Mirza, and Kops-Jones and Spears.
With big ranking points on offer next week in Beijing, a decent run should take Peschke and Srebotnik, who are bidding to reach the Finals for the third time together, across the line.
One team that did their chances no harm in Wuhan were Alla Kudryavtseva and Anastasia Rodionova, whose quarterfinal showing saw them close the gap on Garbiñe Muguruza and Carla Suárez Navarro in seventh place on the leaderboard.
And what of the rest? On the back of their runner-up finish at the US Open and a strong performance in Wuhan, Martina Hingis and Flavia Pennetta have emerged as unlikely contenders for a ticket to the season-ending showpiece. The experienced duo is currently at No.12 on the leaderboard and within striking range of Kudryavtseva and Rodionova.
Momentum may be in their favor, but the numbers are not. They currently trail by a little over 1,200 points and the likelihood is that they will need to triumph in either Wuhan or Beijing and hope results elsewhere go their way to have any chance of reeling the teams above them.
