Gambhir is the fourth Indian batsman in the top 20 after Tendulkar (3rd), Mahendra Singh Dhoni (9th) and Yuvraj Singh (14th).
The Delhi batsman, who lead the run-getters chart with 209 runs in the recently concluded tri-series, was placed at 27th at the start of Bangla tri-series. And if he manages to carry his form into the Asia Cup starting later this month, he has a good chance of of making it to top 15 bracket as only 21 ratings points separate him from 15th placed Kumar Sangakkara of Lanka.
However, the biggest jump in the batting list came from Virender Sehwag, whose 150 runs in the Bangla event has helped him surge ahead by 11 places to 38th.
The Pakistan duo of Salman Butt and Shahid Afridi have achieved career-high rankings owing to their fine shows at Bangla.
Salman, who has made a habit of scoring heavily against India, jumps seven places to 16th spot.
With Mohammad Yousuf occupying fourth place behind South Africa"s Graeme Smith, Australia captain Ricky Ponting and Sachin Tendulkar of India, Butt is the second Pakistani to figure in the top-20 bracket.
His fellow countryman Shahid Afridi made a big leap in rankings for bowler. The leggie from Baluchistan moved four places to stay pretty at 6th spot.
The bowling chart is headed by New Zealand captain Daniel Vettori with Australia"s Nathan Bracken in second spot.
