Only three of the top eight teams on the Road To Singapore leaderboard going into the US Open made it beyond the third round, increasing the probability that the race for the final spots will go down to the wire.
Cara Black and Sania Mirza were one team to avoid the upset bug, reaching the semifinals before running into Martina Hingis and Flavia Pennetta. While their wait for a first Grand Slam final together continues, this run has strenghtened their hold on the fourth Finals berth and in pole position to join the first three qualifiers - Sara Errani and Roberta Vinci, Hsieh Su-Wei and Peng Shuai and Ekaterina Makarova and Elena Vesnina.
With big ranking points on offer in Wuhan and Beijing later this month, Black and Mirza are far from home and dry. A couple of under par showings could see them sucked back into the pack as the scramble for places intensifies.
Another team that did their chances no harm in New York were Kveta Peschke and Katarina Srebotnik, whose quarterfinal showing saw them close the gap on Raquel Kops-Jones and Abigail Spears for fifth place on the leaderboard.
And what of Hingis and Pennetta? After their fairytale in New York, the experienced duo rose to No.12 in the leaderboard and within striking range of the last qualifying spot, currently held by Garbiñe Muguruza and Carla Suárez Navarro.
Momentum may be in their favor, but the numbers are not. They currently trail the Spainiards by a little over 1,000 points and the likelihood is that they will need good showings at both Wuhan and Beijing to have any chance of reeling the teams above them.
