Somdev Devvarman jumped 30 places to reach career best singles ranking of 80 in the ATP charts following his stupendous show at the SA Tennis Open, where he ended runner-up yesterday.
Somdev lost the summit clash to local favourite Kevin Anderson but earned 150 ranking points, that helped him climb the ranking ladder up.
Somdev had broken into top-100 in August last year but kept floating inside and outside that bracket in the next few months.
Comeback boy Karan Rastogi is the next best Indian at number 328.
Meanwhile the re-united partners Mahesh Bhupathi (5) and Leander Paes (6) kept their rankings intact in the doubles chart.
In the WTA ranking, Sania Mirza's ranking was unchanged in both singles (135) and doubles (66). Poojashree Venkatesha was second best ranked Indian at number 514.
