Dubai: India can pip South Africa to second position in the ICC Test rankings if they manage to win their ongoing home series against the West Indies 3-0 and provided Graeme Smith's side loses the upcoming two-Test rubber against Australia.
South Africa trail top-ranked England by seven rating points but lead third-ranked India by just one rating point.
Australia are fourth on 104 rating points.
The maximum third-ranked India can rise from their series against the West Indies is to 119 rating points, which they can only achieve if they win all the three Test matches. A 2-0 series win will leave India on 118 rating points, while a 1-0 or 2-1 series win will keep them on 117 rating points.
A 0-1 series loss against Australia will leave South Africa on 112 rating points while in case of a 0-2 series defeat, the Proteas will join Australia on 110 rating points but will be ranked above Michael Clarke's side when the ratings are calculated beyond the decimal point.
Graeme Smith's side, in contrast, can reduce the gap with top-ranked England to just three rating points if they win both the Tests. South Africa's victory by a 1-0 margin will ensure that they stay ahead of India irrespective of how India's series against the West Indies pans out.
South Africa find themselves in a must-win situation against Australia, if they want to retain their number-two position in the Test Championship table.
