India were third behind Australia and South Africa prior to the start of the series, but the 2-0 win has meant they've gained seven points, and though they are level with South Africa on 116 points, they are ranked second because they are ahead by a fraction of a point.
India won the second Test at Mohali by a whopping 320 runs and then beat the world champions at Nagpur by 172 runs to clinch the Border Gavaskar Trophy, handing the world champions their first defeat since the 2005 Ashes.

Australia have lost nine points as a result of losing the Test series, and that means the gap between them and India and South Africa has been reduced to 13 points.
Australia have a chance to increase the gap again when they take on New Zealand in a two-Test series at home starting next week.
