Match drawn - not entirely surprising since the equivalent of a whole day was fogged off.
With regards to the rankings, the system at the moment is quite complex, but the resultant tables,
here, for both Test and ODI cricket, in my opinion, don't vary too much from what most Test-followers would consider a fair reflection on the abilities of the relative teams.
Australia head the Test table by some way (though not as much as they did before sustaining losses to India and SA in the first test), then India and SA are very closely matched for second, with Sri Lanka 4th and England 5th. As matches and series go on, the older results are 'weighted' less heavily, so that the table reflects recent trends.
Each match does have a bearing on the rankings (for instance, England, incredibly, would've gone second in the ODI rankings in September had the final ODI versus SA not been rained off in Cardiff), but overall, series results count for more, and that is probably how it should be.
India head SA by one point as we speak - had they given England a sporting declaration and lost today, then they would probably have slipped to third, given a series draw. The problem that you get with the rankings - which have only existed over the past decade after
Wisden magazine (now
The Wisden Cricketer) instigated a prototype - is that there is no real schedule, with the Future Tours Programme not really working (Pakistan have not played a single Test match in 2008). Until everyone plays everyone else twice in a four-, five- or six-year cycle, anomalies will be thrown up.
