Dubai, Nov 15 After failing to replace Australia at the top of the Reliance Mobile ICC ODI Championship table earlier this month, India gets a shot at the number-one spot in the longer version of the game when it goes head to head with Sri Lanka in the three-Test series which begins in Ahmedabad on Monday.

Only three ratings points separates first-placed South Africa from third-placed India in the Reliance Mobile ICC Test Championship and all could change as the most challenging and important format of the game returns to action after nearly 10 weeks' break.

India will go on top of the Test table if it beats Sri Lanka by 2-0 or better. In case of a 2-0 win, India will climb to 124 ratings points (two ahead of South Africa) while a 3-0 victory will take Mahendra Singh Dhoni's side to 125 ratings points (three ahead of the Proteas).

India's 2-0 win will drop Sri Lanka from second place to fourth position behind Australia on 115 ratings points while a 3-0 defeat will put Kumar Sangakkara's side on 114 ratings points.

Sri Lanka also has a chance to claim the coveted number-one position. And to achieve this, it simply needs to win the series.

A 1-0 or 2-1 win will take Sri Lanka to 123 ratings points (one ahead of South Africa) while dropping India to 116 ratings points, in fourth position when ratings are calculated beyond the decimal point. A 2-0 victory will lift Sri Lanka to 125 ratings points and will drop India to 114 ratings points.

A drawn series will mean the status quo is maintained.

In the Reliance Mobile ICC Player Rankings for Test batsmen, ICC Test Player of the Year 2009 Gautam Gambhir and Sangakkara resume their fight for the number-one batting slot with the India opener leading the Sri Lanka captain by just nine points. (ANI)
