Sachin Tendulkar [ Images ] is set to lose his top position in the ICC [ Images ] Player Rankings for Test batsmen as he will not feature in India's [ Images ] three-match Test series against the West Indies [ Images ] starting in Kingston [ Images ], Jamaica on Monday.
However, the 38-year-old Indian batsman opting to take rest means losing one per cent of his ratings points for every Test he misses, giving Kallis the sole number one position.
Tendulkar could potentially drop behind England's [ Images ] Jonathan Trott, who though is still in the qualification period for batsmen, is likely to move further up the ladder depending on how he performs in the remainder of the third Test against Sri Lanka [ Images ] in Southampton.
In the ICC Test Championship table, India lead the West Indies by 42 ratings points. As the rankings system is weighed to reflect this difference, anything less than 3-0 whitewash will see India drop points.
India will stay at 128 ratings points only if they win the series 3-0 but will slip to 127 if they win 2-0 while it will drop to 126 ratings points if they win 1-0 or 2-1.
India will drop six ratings points if West Indies win the series 1-0 or 2-1 and seven points in case of a 2-0 win for the West Indies.
A series win by West Indies will not only mean the gap between the top two ranked Test sides will be narrowed, but it will put the Caribbeans ahead of Pakistan in sixth position for the first time since the ratings were introduced in June 2003.
