Hosts and South Africa in excellent form

An analysis of the recent form of batsmen playing in this World Cup

AB de Villiers and Hashim Amla take a run during their 221-run partnership, Netherlands v South Africa, World Cup 2011, Mohali, March 3, 2011

AB de Villiers and Hashim Amla have been in red-hot batting form recently.  •  AFP

In this article I will be looking at the recent form of the batsmen as they get into the World Cup. This will be followed by an article on the bowlers.

It is obvious that both RpI (Runs per Innings) and RpB (Runs per Ball) are important when evaluating the value of a batsman to a team. A batsman A with an RpI of 50 striking at 75 would be essential for building an innings. A batsman B with an RpI of 35 striking at 110 would be essential for finishing an innings. Both qualities are essential. Hence I have devised a simple measure called Batting Index which is a product of the RpI and RpB. Thus these two measures are given equal importance. Using this measure A's Batting Index will be 37.5 and B's index value will be 38.5. This reinforces our assumption that both types of batsmen are essential. Hence in this article I will use the Batting Index as the unit of measurement.

Incidentally a Batting Index of 50 does not exist. The highest is 47.08 for Hashim Amla. AB de Villiers follows at some distance with 42.8. Virat Kohli's index value is just over 40. So a figure of 40 indicates an all-time great batsman like Viv Richards or de Villiers. Index value of 35+ indicates an excellent batsman and 30+ a very good one.

The second important point is Recent Form (RF). If a batsman has played enough number of matches, say 100, the Recent Form, whether great or awful, should not affect his career values greatly. On the other hand, for a batsman who has played in only 20 matches, the RF is likely to be more relevant. Hence I have adopted a varying weight method to determine the overall value, called Weighted Bat Index (WBI). This ranges from 90%/10% for long-standing careers to 50%/50% for very short careers.

Let us move on to the Batting values for Group A.

This table comprises of the top batsmen for the four lead teams in Group A. The table is ordered on the WBI.

Australia has a number of batsmen with WBI values exceeding 30 and this makes them formidable. George Bailey's poor recent form is clearly visible. Also Steven Smith's excellent form is on view. Note the value of James Faulkner in the late order. And David Warner is recently striking at around 100. It can be seen that the top-eight batsmen of Australia will have an average Bat Index value exceeding 30 and this is immense.

Kane Williamson is in what can only be termed as phenomenal recent form: 74.30 at 94. So his WBI is the highest in the group. Since Luke Ronchi has played only 40 matches, his WBI has been capped at 40.0. Both Corey Anderson and Ross Taylor have WBI values exceeding 30. Tom Latham, if he is played, could be the only weak link. In this group, New Zealand is second only to Australia. One could even say they are at par.

England has good numbers, not necessarily as spectacular as New Zealand. These are not earth-shattering by themselves but will make them a formidable opponent when coupled with their excellent bowling numbers. Moeen Ali would be a crucial player in this line-up. Eoin Morgan's recent form, however, is worrying.

Kumar Sangakkara and Tillakaratne Dilshan have been in terrific form recently and this is shown by their excellent WBI numbers. Similarly Angelo Mathews and Mahela Jayawardene are fine and around the 25 mark. But their worry will be the other batsmen: overall quite average. It is almost essential that in any important match two or three out of these four have to do well.

If it is not already known, the WBI of Amla and de Villiers should send shivers down the spines of the opposition. They both have WBI values exceeding 45. Amla's recent form values are 58.1 @ 97.8 and de Villiers' 67.9 @ 123. Only my decision to give these numbers a weight of 10% has kept these to these sub-50 levels. The only worrying factor for South Africa should be Faf du Plessis' indifferent recent form which is more than offset by Riley Rossouw who has a nominal WBI of 25.00.

The overall numbers for India are quite good. However this is to a great extent due to excellent career numbers and the Sri Lankan ODI series. But there is no doubt that the Indian team is potentially a devastating batting team. Of course Napier is not Nagpur and Perth is not Pune. Specifically India needs a quarter-final opponent like Sri Lanka to have a 50-50 chance of going through to the semi-final.

That Shahid Afridi leads the Pakistani table should be cause for worry for them. His recent form has been excellent. Misbah-ul-Haq is fine. But look at the other players like Umar Akmal and Younis Khan. If Pakistan has to do well, these two have to come to the party. In the last 15 innings, Younis Khan has one hundred and no other innings in excess of 35. In the last 10 innings Umar Akmal has not reached 50.

For West Indies, Andre Russell is striking well but Chris Gayle is in poor form. Marlon Samuels has been playing very well as also Denesh Ramdin. Darren Sammy is doing very little as a batsman. Jason Holder's numbers are so poor that he cannot be considered even as an all-rounder. West Indies are dependent on Gayle a lot. If he can finish the WC with an RpI of 50 striking at 100, they would do quite well.

These are the numbers for the other six teams. Based on these numbers it is easy to conclude that Bangladesh and Ireland have the good players to give these teams some chance of a surprise or two. Scotland is also good. But most of the matches which Scotland and Ireland have played would be against the other Tier-2 teams. Hence the figures for Zimbabwe look promising. In conclusion it is possible to think of a top team, which has an off day, losing to these teams. However for them to string together the wins needed to move them to the quarterfinals is something else. While West Indies could lose to Ireland one day, they are eminently capable of defeating India in the next match. So it does not take rocket science to conclude that the teams from the Tier-1 are likely to be in the quarter-finals.
