The Olympic bronze medallist, however, has a good chance to climb up once again if she progresses to the semi-finals or final of the ongoing India Grand Prix Gold here.
World Championship bronze medallist P.V. Sindhu, however, maintained her No.11 ranking and is also expected to rise up the ladder when next week's rankings are released.
It was good news for the top male shuttlers though as Parupalli Kashyap jumped two places to No.18 while Mumbai's Ajay Jayaram rose a place to No.21.
No Indian, however, figures in the top-25 of the men's, women's and mixed doubles rankings.
