Milos Raonic and Jo-Wilfried Tsonga were among the surprise first-round casualties at the ATP & WTA China Open in Beijing on Monday.

Serbia's world number 24 Viktor Troicki saw off fifth seed Raonic 6-4 6-4 in 76 minutes, holding the 6ft 5in Canadian to four aces and breaking his serve twice, dealing a blow to Raonic's hopes of reaching the season-ending Barclays ATP World Tour Finals.

Tsonga, coming off his first title of the year in Metz last month, led 5-3 in the first set against Andreas Haider-Maurer but the unseeded Austrian rallied for a 7-6 (7/4) 6-2 victory which earned him a second-round date with Jack Sock.

American Sock won 88 per cent of first-serve points en route to a 6-4 6-3 triumph over Russia's Teymuraz Gabashvili.

Seventh seed David Goffin of Belgium and Italy's Fabio Fognini advanced comfortably to round two, ousting Andreas Seppi and Martin Klizan respectively.

Home favourite Zhang Ze overcome a second-set wobble to defeat Uzbekistan's Denis Istomin 6-3 1-6 6-3, while Czech Lukas Rosol recovered from a set down to beat Great Britain's Aljaz Bedene 1-6 7-6 (8/6) 6-3.

In the women's first round, 13th-seeded German Andrea Petkovic progressed when, leading Eugenie Bouchard 6-2 1-1, the Canadian retired due to dizziness and left the court in tears.

"I thought I was physically ready but unfortunately the symptoms of my concussion came back," Bouchard said, following a disappointing first competitive match since withdrawing from the US Open.

She added in a statement quoted on www.wtatennis.com: "I want to thank all my fans at the China Open for their support. I hope to get well soon and look forward to returning next year."

Also in the first round, former US Open champion Samantha Stosur cruised past Monica Niculescu 6-3 6-2, while 11th seed Belinda Bencic and Mirjana Lucic-Baroni posted three-set wins over Madison Brengle and Irina-Camelia Begu respectively.

In second-round action, fourth seed Agnieszka Radwanska survived a scare on her way to defeating Mona Barthel of Germany 4-6 6-1 6-4.

She will next face Madison Keys after the 14th-seeded American also overcame a shaky start to get past Ukraine's Kateryna Bondarenko 3-6 6-1 6-0.

Seventh seed Carla Suarez Navarro advanced with a 7-6 (7/1) 6-2 triumph over Monica Puig, while Svetlana Kuznetsova overcame American Sloane Stephens 3-6 6-3 6-4 and 15th seed Roberta Vinci downed Belgian Alison Van Uytvanck 6-2 6-2.

One seed sent on her way in the women's draw was Elina Svitolina. Russia's Anastasia Pavlyuchenkova saw off the 16th seed from Ukraine 6-4 1-6 6-3.

Genie Bouchard, Milos Raonic out of the China Open

Eugenie Bouchard did not make it through her first match since returning from a concussion suffered at the U.S. Open. She withdrew in the second set of her match with Germany’s Andrea Petkovic at the China Open today.

Petkovic took the first set 6-2, with the second stanza tied 1-1 when Bouchard was unable to continue, burying her face in her towel in tears on the court in Beijing. She was complaining of dizziness.

Petkovic, the No. 13 seed, came over and appeared consoling, offering words of encouragement to the very disappointed Bouchard.

Genie Bouchard was having a bad year, losing six matches in a row at one point. Just when it was turning around, it got worse. The concussion the Canadian tennis player is dealing with, followed a fall in the dressing room after her third-round win against Dominika Cibulkova at the U.S. Open. She slipped on a wet floor and fell backwards hitting her head.

Diagnosed with a concussion she was forced to withdraw ahead of her fourth-round singles match and the doubles competitions she was entered in. She also pulled out of the Tokyo Open as the tour moved to Asia.

A year ago Bouchard was the darling of women’s tennis having soared to fifth ranking, she is now ranked 38th. But she’ll be back.

Milos Raonic did not fare so well either. The hard server from the Greater Toronto area fell to Serbian Viktor Troicki in straight sets, losing in the first round 4-6, 4-6.
