A semi-final appearance at the Aptos Challenger tournament helped India's ace tennis player Somdev Devvarman rise back to his career-best singles ranking of 103 in the ATP charts.
Somdev lost to Donald Young in the last four stage but the effort was enough for him to jump two places up.
Yuki Bhambri, who has resumed practice after nursing a broken ankle, has lost 14 positions to slip to 489th spot.
In the doubles chart, veterans Leander Paes (6) and Mahesh Bhupati (7) kept their places in the top-10 while Rohan Bopanna rose a rung to career-best 38.
Meanwhile, a struggling Sania Mirza gained a position to be at 131 in the WTA singles chart.
