Canada's Fernandez, Indonesia's Tjen ousted in 2nd round of women's doubles at U.S. Open

Canada's Leylah Fernandez and Indonesia's Janice Tjen fell 6-4, 6-4 to New Zealand's Erin Routliffe and Indonesia's Aldila Sutjiadi in second-round women's doubles action at the U.S. Open on Saturday.

Fernandez and Tjen had one ace to six double faults and only converted on one of their six break-point chances.

Meanwhile, the ninth seeds Routliffe and Sutjiadi had one ace, two double faults and broke on three of their five opportunities.

Fernandez of Laval, Que., was also ousted in third-round women's singles play on Friday by third-seeded American Jessica Pegula.

Dabrowski and women's doubles partner Luisa Stefani of Brazil face Austria's Lilli Tagger and Italy's Sara Errani in the second round later Saturday.

Olympic gold medallist Zheng Qinwen extended her return to the U.S. Open with a spectacular and stunning rally, winning the final seven games to eliminate No. 22 Madison Keys 1-6, 7-6 (3), 7-5 on Saturday.

Amanda Anisimova, like Keys a past runner-up at the U.S. Open, also was knocked out when the No. 10 seed lost to No. 24 Anastasia Potapova 6-2, 7-5.

Keys won a three-set match in the previous round in a match tiebreaker when she fought off five match points. Two days later came a collapse that was as out-of-nowhere as that comeback.

The 2017 runner-up rebounded after losing the second-set tiebreaker to charge out to 5-0 lead. Zheng held but Keys had a match point while serving at 5-1, and once she couldn't convert that, the turnaround was on, with Keys at one point banging her racket into her head repeatedly and pulling off her visor in disgust.
