A 3-0 whitewash will help the Indian team reclaim the no.1 spot from South Africa.
India are already the top-ranked in Test cricket and are on 120 points in the ODI rankings, only one point behind South Africa.
With a win in Dharamshala on Sunday, India will edge ahead of South Africa to take the no.1 spot.
India will reach 121 points and edge South Africa on decimal points if they take a 1-0 lead in the series but will have to also win the following two matches in Mohali and Visakakhapatnam on 13 and 17 December if they want to keep the lead since Sri Lanka are eighth on the table with 83 points and the rankings system is weighted to reflect the difference in ranking points
India will slip to 119 points even with a 2-1 win in the ODI series, which follows a three-Test series between the two sides, which India won 1-0.
On the other hand, eighth-ranked Sri Lanka will remain on 83 points even with a 3-0 loss but can go up to 87 points with a 3-0 series win.
