With the gap between test matches at the moment, it's a good time to look at the numbers again.
I looked at all players who had faced at least 250 balls in 20 or more innings in last 3 years. I also restricted it to players who had at least 7 innings of less than 20 and at least 7 innings of 20 or more in that time.
For the average from 20, I subtracted 20 from their average in innings with a total score of 20+.
Here are the players who have the biggest positive difference between their average from 0 and their average from 20.
| Name | Innings 20+ | Innings under 20 | Average | Average 20+ | Difference |
| MS Wade (Aus) | 7 | 15 | 34.61 | 96.25 | 61.64 |
| MG Johnson (Aus) | 8 | 23 | 17.85 | 56.40 | 38.55 |
| CA Pujara (India) | 12 | 10 | 65.55 | 101.88 | 36.33 |
| IR Bell (Eng) | 28 | 20 | 56.15 | 84.31 | 28.16 |
| AN Cook (Eng) | 32 | 29 | 55.59 | 82.20 | 26.61 |
| KC Sangakkara (SL) | 32 | 21 | 62.48 | 84.48 | 22.00 |
| JH Kallis (SA) | 26 | 17 | 63.47 | 84.61 | 21.14 |
| SCJ Broad (Eng) | 12 | 24 | 24.36 | 45.00 | 20.64 |
| MJ Prior (Eng) | 29 | 21 | 50.82 | 70.52 | 19.70 |
| MJ Clarke (Aus) | 32 | 25 | 53.70 | 73.27 | 19.57 |
| M Vijay (India) | 9 | 11 | 40.25 | 58.77 | 18.52 |
| KP Pietersen (Eng) | 28 | 25 | 48.50 | 66.80 | 18.30 |
| RT Ponting (Aus) | 20 | 24 | 34.52 | 52.27 | 17.75 |
| HMRKB Herath (SL) | 10 | 29 | 17.85 | 35.00 | 17.15 |
The two names at the top of this list were fascinating. I had no idea that those two had been so good at capitalising on a start. It suggests that early wickets down the order will be very important for England in the upcoming Ashes series.
The other end of the table is the players who have a tendency to throw away their wickets after getting a start.
| Name | Innings 20+ | Innings under 20 | Average | Average 20+ | Difference |
| AN Petersen (SA) | 29 | 12 | 37.64 | 28.17 | -9.47 |
| EJM Cowan (Aus) | 19 | 11 | 32.9 | 27.78 | -5.12 |
| AB de Villiers (SA) | 34 | 9 | 70.34 | 66.00 | -4.34 |
| GP Swann (Eng) | 15 | 22 | 19.15 | 15.53 | -3.62 |
| SR Watson (Aus) | 27 | 17 | 32.48 | 29.50 | -2.98 |
| DG Brownlie (NZ) | 13 | 8 | 32.8 | 29.91 | -2.89 |
| HAPW Jayawardene (SL) | 17 | 15 | 30.57 | 28.00 | -2.57 |
| G Gambhir (India) | 23 | 18 | 30.57 | 28.21 | -2.36 |
| AJ Strauss (Eng) | 29 | 19 | 34.06 | 32.67 | -1.39 |
| Tamim Iqbal (Ban) | 13 | 9 | 37.86 | 37.07 | -0.79 |
| GC Smith (SA) | 30 | 17 | 44.4 | 44.07 | -0.33 |
| AB Barath (WI) | 11 | 13 | 21.58 | 21.90 | 0.32 |
| V Kohli (India) | 19 | 12 | 41.96 | 42.94 | 0.98 |
| CS Baugh (WI) | 9 | 17 | 17.25 | 18.25 | 1.00 |
It's surprising to see two openers at the top of this list. These two do the hard work regularly, both getting to 20 roughly twice as often as they don't, but then they don't make the most of it. In fact it was a tweet from Gary Naylor from 99.94 that made me think about redoing this analysis, as Cowan's record is quite remarkable.
Does any opening bat get in and get out more often than Ed Cowan? 40 and 35 vs Durham - but he seems to score that in every match!

It made me wonder where these two sat overall among openers. Using the same conditions, I compiled this list, looking only at innings where a batsman was opening the batting:
| Name | Innings 20+ | Innings under 20 | Average | Average 20+ | Difference |
| AN Petersen (SA) | 31 | 11 | 38.36 | 28.96 | -9.40 |
| CM Spearman (NZ) | 17 | 12 | 23.96 | 16.70 | -7.26 |
| RW Barber (Eng) | 22 | 11 | 38.62 | 31.54 | -7.08 |
| BM Laird (Aus) | 26 | 14 | 35.28 | 29.76 | -5.52 |
| H Sutcliffe (Eng) | 65 | 18 | 61.10 | 55.82 | -5.28 |
| A Turner (Aus) | 17 | 10 | 29.53 | 24.25 | -5.28 |
| CJ Barnett (Eng) | 14 | 7 | 39.65 | 34.53 | -5.12 |
| BK Kunderan (India) | 13 | 8 | 41.15 | 36.15 | -5.00 |
| UC Hathurusingha (SL) | 25 | 17 | 30.73 | 26.12 | -4.61 |
| Imran Farhat (Pak) | 45 | 31 | 31.85 | 27.25 | -4.60 |
| GS Camacho (WI) | 12 | 9 | 30.33 | 25.75 | -4.58 |
| B Wood (Eng) | 10 | 11 | 21.61 | 17.50 | -4.11 |
| EJM Cowan (Aus) | 18 | 11 | 33.20 | 29.11 | -4.09 |
| RB Simpson (Aus) | 52 | 18 | 55.51 | 52.00 | -3.51 |
| JB Hobbs (Eng) | 70 | 27 | 56.37 | 52.98 | -3.39 |
| Imrul Kayes (Ban) | 12 | 20 | 17.15 | 13.91 | -3.24 |
| SM Katich (Aus) | 42 | 19 | 50.48 | 47.46 | -3.02 |
| IR Redpath (Aus) | 40 | 19 | 44.50 | 41.57 | -2.93 |
Both batsman make this list, with Alviro Petersen again clear at the top. Interesting to note that three of the batsmen regarded as some of the greatest openers ever (Herb Sutcliffe, Jack Hobbs and Bobby Simpson) on the list.
The final batsman that I want to look at is Ross Taylor. He was near the bottom of the list last time I did this analysis, with an average of 40.21 and then 40.38 once he got to 20 (a difference of 0.17). In the past 3 years he has improved both numbers. This time he has averaged 41.79 and then 47.73 once he gets to 20 (a more respectable difference of 5.94). Perhaps he actually is the player who will disprove Martin Crowe's infamous assertion that Polynesian players didn't have the concentration required for cricket.
