Yuki Bhambri, though, lost a place to sit at the 398th spot.
There was no change in the doubles rankings of Leander Paes (6) and Mahesh Bhupathi (7) but Rohan Bopanna (50) returned to top-50 with a jump of four places.
Meanwhile in the WTA rankings, Sania Mirza (91) maintained her singles ranking but lost two places (75) in the doubles chart.
Sania is making a comeback to competitive tennis at Aegon Classic in Birmingham on Mondy after a long injury break.
