India [ Images ] could be dislodged from the top position in the ICC [ Images ] One-day rankings by South Africa [ Images ] if the Proteas manage to whitewash Pakistan in a five-match home series starting on Sunday.
If the Proteas achieve this series result, then the side will win the ODI Shield as well as $175,000 as the top three sides have no ODIs scheduled before the April 1 cut-off date and South Africa's position will be assured.
South Africa have previously won the ODI Shield twice, first, when it finished as the No 1-ranked ODI side in 2008 and then again in 2009.
If South Africa win the series 4-1, then they will move ahead of England into second position and will collect a cheque of $75,000 to compliment the prestigious mace and $450,000 which they have already won by sealing the No 1 position on the Test Championship table.
In contrast, sixth-ranked Pakistan can move to as high as the fourth spot. But for this to happen, they will have to whitewash SA in the ODIs series.
If Pakistan blank out South Africa, then they will jump from 107 ratings points to 114 ratings points, while South Africa will drop 10 ratings points and plummet to 102 ratings points.
If Pakistan beat South Africa 3-2, then both sides will be locked at 109 ratings points, but South Africa will be ranked above when the ratings are calculated beyond the decimal point.
