My sentiments exactly. For 5 days I heard how Cummins negative fields were unjustifiable tactical idiocy, yet declaring the first evening of a test was some genius move. The English press and commentators have become pretty nauseating in their bazball mania. The truth is, through all the excitement and verbal masturbation, no one could really give me any answer as to why the declaration was a good idea.
Actually, we did get one - that they might snag a wicket in the evening before the end, without any real discussion or appreciation of the cost or likelihood of that occurring. I mean, looking at some stats to put this decision into context. Since 2000 in tests....
- Its impossible to isolate the stats for partnerships on balls faced, but going a roundabout way on RR and runs scored, for the 4 overs available to get a wicket, you had about a 25% chance of getting on in the first 4 overs. It is again, impossible with the stats to isolate partnerships inside the total scored, so this is a stat based on a much lower average total scored than those in the first innings of the match. So one would expect with higher totals, the average opening partnership would be longer, and the likelihood of a wicket even less, but its impossible to gauge.
- Would an early wicket actually have been a net benefit considering England lost two wickets in its possible pursuit?
(i) The average 10th wicket partnership is 13
(ii) The average number 10 bat who gets a start of 17 runs, averages 39.
(iii) The average opener scores 4 when dismissed inside a 24 ball period. Which is 33 runs less than average.
So, in actual fact, the average case here is England would lose out on -2 runs even in the 25% chance they succeeded.
(iv) Worth noting that Edgbaston has the 5th highest average last wicket partnership in cricket, and the only ground that has seen 2 x 100 partnerships in the data period, with a further 7 x 50. All those grounds averaging more have negligible sample sets. So it's pretty much the best full time test ground in the world for tailenders to bat in the last 23 plus years. Also Joe Root and Anderson hold the all time 10th wicket partnership, and not sure how many 10s in world cricket have a FC record like Robbo... which all increases the potential score over average.
- Scoreboard pressure
(i) Teams batting first scoring 393(England's score) to 400, loss more than they win (win ratio only 0.875).
(ii) Increasing that by only 10 runs to 400-410, increase the ratio to 1.1... there is no effect on the draws.
(iii) Adding the average expected lost runs in declaring (428) and using that as the same range (423-433).... the ratio goes up to 1.8 wins to losses
(iv) In all cases, the ratio of draw remains roughly the same (in fact, its worse with the lower scores)
Small increases in upwards scoring past 400 create huge scoreboard pressures, and are far more worth in dictating victory.
