London: After the tremendous excitement and massive success of the ICC World Twenty20 2009, focus now shifts to the 50-over format when the West Indies and India go head to head in the four-match series with the latter needing a clean sweep to go into second position in the Reliance Mobile ICC ODI Championship table.

India currently sits with Australia on 122 ratings points but behind Ricky Ponting's men in third place by a fraction of a point. However, if India sweeps the series, it will gain one rating point which will allow it to claim second place in the championship for the first time since the rankings were introduced in October 2002.

India is 32 ratings points ahead of eighth-placed the West Indies and that gap means it is expected to win the series comfortably. If it fails to do so then its rating will suffer and it will lose one point to drop behind Australia even if it secures a 3-1 success. A 2-2 draw series will put India on 119 ratings points and a 4-0 defeat will drop it to 116 ratings points, just four points ahead of fourth-placed New Zealand.

In contrast, the West Indies, which will start the series on 90 ratings points, will gain nine ratings points in case of a 4-0 series win to narrow the gap with seventh-placed Sri Lanka by six points. A 3-1 series win will lift it to 96 ratings points, a 2-2 draw series will take it to 93 ratings points and a 3-1 loss will leave it on 91 ratings points. The West Indies will concede two ratings points if India wins all the matches of the series.

In the Reliance Mobile ICC Player Rankings for ODI batsmen, Dhoni leads the field but Shivnarine Chanderpaul, Chris Gayle and Yuvraj Singh are breathing down his neck as only 46 points separate number-one-ranked Dhoni from fourth-placed Yuvraj.

Gautam Gambhir (16th) and Ramnaresh Sarwan (19th) are the other batsmen from either side inside the top 20.

In the Reliance Mobile ICC Payer Rankings for ODI bowlers, Jerome Taylor is the highest-ranked bowler from either side in 14th place while Zaheer Khan is just one point behind in 16th position and Daren Powell in 20th spot. Harbhajan Singh is just outside the top 20 in 23rd place.

The bowlers' table is headed by Sri Lanka's Nuwan Kulasekara with New Zealand's Kyle Mills second and Muttiah Muralidaran third.

In the Reliance Mobile ICC Player Rankings for ODI all-rounders, Yuvraj has an excellent chance to leapfrog England's Andrew Flintoff in second place as the Indian trails the Englishman by just six points.

Shakib Al Hasan of Bangladesh is on top of the all-rounders' list while the Pakistan duo of Shahid Afridi and Shoaib Malik in joint-fourth spot complete the top five.
