After grabbing a 5-3 lead in the opening set, Wang Qiang plummeted to a 10-game losing skid, bowing out to former world No 1 Caroline Wozniacki 7-5, 6-0 in the second round of the China Open on Tuesday.

Wang's exit meant Chinese women lost the chance to move on, as Han Xinyun, Zhang Shuai and Zheng Saisai had already crashed out in the first round.

It was Wang's second main draw appearance in Beijing since 2012. She advanced by beating Varvara Lepchenko in first round for her third win over a top-100 opponent.

Wang and Wozniacki, ranked 11th, had previously met in Kuala Lumpur in 2013, where Wang managed a 2-6, 7-6(1), 6-1 victory.

Both players shared breaks in Tuesday's first seven games, and then Wang secured her serve to build up a 5-3 lead.

Things began to change after the eighth game as Wang committed more unforced errors and Wozniacki took advantage to rebound for the 7-5 victory.

Wozniacki continued her momentum in the second set, cruising to a 6-0 sweep in just 79 minutes.

"The loss in the first set, especially after I had the advantage, affected my confidence and morale for the later games," said Wang.

"Caroline played very well, and gave me a lot of pressure all through the match."
