When was the Ashes won?
The important old ball |
An interesting question, however, is what parts of the games did England win? It's hard not to recognise the efforts of Ian Bell, who has been immense for England with the bat, often on quite difficult surfaces. Despite his efforts, I think there has been another factor that has been equally influential. England's pace bowlers have bowled well with the old ball.
For the purpose of this article, I've defined the ball as being new if it is less than 20 overs old, and old if it's more than 20 overs.
Here are the difference between the two sets of pace bowlers:
Average | Australia | England |
less than 20 overs | 22.78 | 32.32 |
more than 20 overs | 35.28 | 28.78 |
Australia are significantly better with the new ball, but England are better with the old ball. While those 7 runs per wicket doesn't seem like a big difference, it is because there have been just over twice the number of overs bowled with the old ball as with the new ball.
Part of the difference has been that Australia seem to have worked hard to keep the shine on the ball, while England seem to have been trying to get the ball to reverse, and not been so worried about using the first new ball as a weapon. England have done much better with the second new ball than with the first (England average 4 runs per wicket more with the first new ball than with the second), while Australia have been the opposite (Australia average 5 runs per wicket more with the second new ball than with the first). Their bowlers almost seem to have run out of steam once the second ball comes along.
Here's how it works out as averages scores. After 20 overs Australia's average score is about 66/2. England is 58/3. However after 80 overs Australia average 180/9 while England are 225/7. Some of that difference is Graeme Swann, but some of that is just how much more effective England's quick bowlers have been with the older ball.
If we took spin bowlers out of the picture and just looked at the fast bowlers, After 20 overs Australia would still average 66/2 (Swann had been about as effective as the quicks with the new ball). England would have been 47/3. After 80 overs Australia would average 250/9 while England would still have 3 wickets in hand at 211/7.
There's a point, however, where these numbers are ridiculous, as the different batsmen are not equally capable, but they do paint a picture.
However they are ignoring the impact that Swann has on the bowlers that are bowling with him.
I believe that one of the reasons that England's quicks have been so effective with the old ball is the pressure created by Graeme Swann. To quantify this pressure, I looked at a statistic that I called Wicket Assists. A wicket assist is awarded to a bowler who bowls an over directly preceding the one where a wicket fell.
Wicket assists is a statistic that I keep note of when I'm coaching, as it's often a better indicator of how much pressure a bowler is exerting on the batsmen than wickets. An example of this is when I had two bowlers opening the bowling together. One bowled 6 overs, and took 0/8 (included 2 no balls, and a wide that just slipped down the leg side). The other bowled 7 overs and took 6/47. Most of the wickets for the second bowler were a result of the pressure that the first bowler built up. The second one got to keep the ball, and got the plaudits, however the one that I recommended for a higher team was the first bowler.
Graeme Swann has taken 23 wickets in this series, but he has also had 23 wicket assists. That's roughly one wicket every 9 overs while he's at the bowling crease. He creates pressure that allows the quick bowlers to take wickets. Compare his rate to Ashton Agar, who had 2 wickets and 5 assists in the two matches he played. That's a wicket roughly every 24 overs that he's at the crease. Nathan Lyon has been more successful than Agar at exerting pressure. 8 wickets and 6 assists, meaning that Australia pick up a wicket roughly every 11 overs that he's at the crease.
Overall I believe that one of the major differences between the two teams has been what their bowlers have done after 20 overs. England's quick bowlers have been better, and their spinners have been better too. Overall, I believe this is the time that this series has been won.

Another first innings spinner
A couple of years ago I wrote a post about Daniel Vettori, showing that he was much more effective in the first innings than in the second innings.
Among spin bowlers who have taken more than 250 wickets, Vettori is alone in this, but among bowlers who have taken less wickets there are a few others. Here's the list of regular spin bowlers who started their careers post 1978 and who have a second innings average higher than their first innings average.
It's a fairly short list, but the interesting thing is the last three names on it. Vettori and Qadir are two outstanding bowlers. But they both have quite similar records to Nathan Lyon.
I thought it would be interesting to look at the three bowlers together, after they had all played the same number of matches as Nathan Lyon has:
We can see that Vettori started off his career more conventionally, being more effective in the second innings. But the thing that stands out to me is how much more effective Lyon is at taking wickets than either of the other two. His strike rate is remarkable. (To put his strike rate in context: at the same stage of his career Warne had a strike rate of 67.4) Lyon's overall average and strike rate is also better than Vettori's or Abdul Qadir's was after 24 matches.
It seems that the Australian selectors and public are still somewhat unconvinced by Lyon, but I think that if he can hold his own in a comparison with Vettori and Abdul Qadir, then he is probably a bowler worth persevering with.

Mini-session Analysis, 4th Ashes Test, Chester-le-Street, 2013
Here is the mini-session analysis for the fourth test between England and Australia at Riverside Ground, Chester-le-Street, England
A mini-session is (normally) half a session, either between the start of the session and the drinks break or the drinks break and the end of the session. Occasionally a long session will have 3 mini-sessions where it will be broken up with 2 drinks breaks.

Is Brendan Taylor doing too much?
Happier times for Brendan Taylor: captain, but not keeper |
Some of that may have been due to India having done their homework on him. Duncan Fletcher is a clever coach, and will have been aware that Taylor is capable of winning games almost single handedly with a big innings. In 128 innings against good opponents (test teams or Ireland) he has 6 ODI hundreds. To put that in context, at a similar point in his career, Jayasuriya had 5 ODI hundreds. It would have been, therefore, negligent of India to have not had specific plans for Taylor.
But as much as that may have been a factor in this series (and also potentially in the last two against West Indies and Bangladesh where Taylor was also ineffective) there was possibly something else going on. In the last few matches he has been keeping wickets and captaining the team. Some players thrive when given the gloves and the captaincy, but most players find their batting suffers when they are both captain and keeper.

A terrible decision
Anyone who is an opponent of DRS has just got a whole lot of ammo. The problem is not the system (in my opinion) it's the implementation. The idea that there needs to be clear evidence to overturn a decision is fine, but I genuinely think that the decision to give Usman Khawaja out was appalling.
International cricketers need to be careful about how they talk about umpires, but Jimmy Neesham didn't hold back, with this tweet:
