Juan Sebastian Cabal and Robert Farah duplicated their recent success against World No. 1s Bob and Mike Bryan on Thursday in Shanghai. The unseeded Colombians rallied to take out the top-seeded Americans 6-7(1), 7-6(7), 10-7 to reach the quarter-finals.

For the Bryans, it was a second setback against Cabal/Farah in as many weeks, the Californians having dropped a Match Tie-break in the round of 16 against the eventual Tokyo finalists just a few days ago. They were up a set and a break, then held match point at 6/5 in the second-set tie-break, but saw their opponents roar back to take the match. The top seeds made eight of nine first serves in the Match Tie-break, but dropped four of nine service points to bow out in one hour and 51 minutes.

The Bryans currently lead the way with 6,285 Emirates ATP Doubles Race To London points and are closely pursued by Jean-Julien Rojer and Horia Tecau (5,950 points). However, the second-ranked team will not be making up ground in the Race To London this week, as it was sent packing by Feliciano Lopez and Max Mirnyi 7-5, 7-5 in 78 minutes on Thursday. Lopez/Mirnyi only made 62 per cent of first serves compared to their opponents’ 72 per cent, but had twice as many break point chances (10-5) and breaks of serve (4-2).

In the quarter-finals, Cabal/Farah will take on No. 7 Daniel Nestor/Edouard Roger-Vasselin, while Lopez/Mirnyi will face No. 8 Rohan Bopanna/Lukasz Kubot.
