Tokyo: World number three Wang Xin failed to clear the second round when she bowed to unheralded Tai Tzu-ying of Taiwan at the Japan Open on Thursday, but there was no such trouble for India's Saina Nehwal.
Saina needed some time before getting into her rhythm to score a 21-17, 21-16 victory over the Vietnam Open champion Fu Mingtian of Singapore.
"I started a bit slowly. She is very good and I didn't know how she plays. I started a bit nervous, but after that I played very well," said Nehwal, who claimed five titles last season and is a pin-up at home.
