Karan Rastogi reaped the benefits of his positive show at last week's Chennai Open by making a leap of 109 places in the latest ATP Tour men's tennis rankings.
The 20-year old Mumbaikar jumped to 371st place following his win against 106th ranked Brazilian Thiago Alves in the first round at Chennai.
His spirited performance, however, came to an end with a second round loss to world number two Spaniard Rafael Nadal at the USD 416,000 hard court event where he played as a wild card.
Leander Paes too tasted the fruits of hard work.
The Indian star, pairing with US Open winning partner Martin Damm of the Czech Republic, climbed one place to 11th in doubles rankings, thanks to their reaching the final at the Qatar Open in Doha.
Paes' compatriot and adversary Mahesh Bhupathi, who did not play last week, stayed at 30.
Rohan Bopanna, who played with Sania at the Hopman Cup last week, slipped 28 rungs to be 290 but was still the highest-ranked Indian in the singles.
On the WTA Tour, Sania Mirza retained her 2006 year-end ranking of 66. The 20-year old Indian was 24th in the doubles.
Shikha Uberoi was placed at 208 and Ankita Bhambri 414th in singles.
