Cape Town - The Proteas could move back to the No 1 spot in the ICC ODI rankings if they whitewash Bangladesh in their upcoming ODI series.
Last month, India overtook South Africa after their 4-1 win against Australia at home, which left Virat Kohli's charges currently one point ahead of the Proteas on 120 points.
However, the Proteas will go ahead of India - on decimal points - with a 2-0 lead in the three-match ODI series against Bangladesh and would reach 121 points with a 3-0 whitewash.
However, Faf du Plessis' men will only remain at the top if India are unable to win the opening match of their three-match ODI series against New Zealand, which will be played on the same day as the final ODI between South Africa and Bangladesh - on October 22.
If India defeat the Black Caps in their clash, they too will be on 121 points - but ahead on decimal point calculation.
However, India will have to go on to win the series against New Zealand 3-0 to retain the top spot as anything less than that scenario will see the Proteas regain the No 1 position - should they triumph 3-0 over Bangladesh.
