To do this I used a modified batting index score. Batting index is basically the average multiplied by the runs per ball. It is a good measure of how effective a batsman is in limited overs cricket. The problem with using it for single innings is that anyone who gets not out has an infinite score. To counter this I have created a modified index, that I'm going to call innings value. To calculate this there are two options. If the batsman is out, then it is his score multiplied by his score minus 5 divided by the number of balls he faced. For example, if someone got out for 90 off 45 balls his score would be 90 x 85 / 45 or 170. If a batsman gets not out it is his score squared divided by the balls faced. I chose to subtract 5 as when I did an analysis on the cost of wickets each wicket that fell tended to cost a team 5 runs. So if a batsman gets out his team scored 5 runs less (on average).
Here are the top 10 innings this year:
| name | score | balls | Against | At | Value |
| RE Levi (SA) | 117* | 51 | v New Zealand | Hamilton | 268.41 |
| PR Stirling (Ire) | 79 | 38 | v Afghanistan | Dubai (DSC) | 153.84 |
| MJ Guptill (NZ) | 91* | 54 | v Zimbabwe | Auckland | 153.35 |
| CH Gayle (WI) | 85* | 52 | v New Zealand | Lauderhill | 138.94 |
| KA Pollard (WI) | 63* | 29 | v New Zealand | Lauderhill | 136.86 |
| AD Hales (Eng) | 99 | 68 | v West Indies | Nottingham | 136.85 |
| BRM Taylor (Zim) | 75* | 43 | v New Zealand | Hamilton | 130.81 |
| PR Stirling (Ire) | 61* | 32 | v Canada | Dubai (DSC) | 116.28 |
| WTS Porterfield (Ire) | 56* | 27 | v Kenya | Dubai (DSC) | 116.15 |
| CA Ingram (SA) | 78 | 50 | v India | Johannesburg | 113.88 |
Now there are a few scores in here against 2nd tier nations, but those runs still had to be scored, and so I feel they merit a place in this list. Paul Stirling managed to make the list twice in the tournament in Dubai.
Both of yesterday's innings are in the top 10, and are both ranked about the same as Hales 99 and Taylor's 75*, which feels about right. Both would have been match winning scores in most situations, and coming together in the same match made the West Indies target completely unreachable for New Zealand. It will be interesting to see if there is a repeat dose today.
It also highlights just how good Levi's innings in Hamilton was, in that he scored faster than Pollard, but for almost twice as long.
