Arvind Bhatt, who finished runners-up in the Bitburger Open, has also surged four places up to 36th while Olympian Anup Sridhar was at the 37th spot.
The mixed doubles pair of V Diju and Jwala Gutta, who were the first Indian pair to win a grand prix event by clinching the Bitburger Open mixed doubles title, climbed 25 places to the 55th spot.
