Osaka (Japan), Sep 3 Olympic champion Chen Yufei suffered her second defeat in a week to Akane Yamaguchi of Japan in the women's singles semifinals of the Japan Open badminton tournament here on Saturday.
Yamaguchi, who beat Chen in a three-set thriller in the world championships final last Sunday, fought back from one set down and 14-9 behind in the third set to win 15-21, 21-16, 24-22.
The Japanese star has beaten Chen five times in a row and improved her record to 15 wins and eight losses.
"I tried to do something different from what I did last week. It worked in the first set. But in the second and third sets, Yamaguchi was faster and more confident," Chen said.
