FINGER SPINNERS IN AUSTRALIA - Part 1
Its very interesting to see how finger spinners in general and off spinners in particular have fared in Australia. I did a study of this and have updated the figures to include the last test series of Sri Lanka.
- For this analysis, I have included all finger spinners (as the term is generally understood) who have taken at least 100 test wickets.
- I excluded those who played often primarily as a batsman thus excluding people like Shastri, Mankad and Sobers.
- I excluded people who played just a single test in Australia like Harbhajan.
This gave me 27 bowlers in all - 14 left arm and 13 right arm (including Murali). Here is the complete list.
Code:
[B]Left Arm Right Arm[/B]
Bedi Allen, David
Blythe Bracewell
Doshi Emburey
Edmonds Gibbs
Giles Illingworth
Lock Laker
Peel Mallett
Qasim Murali
Rhodes Prasanna
Tufnell Saqlain
Underwood Tayfield
Valentine Titmus
Verity Yardley
Vettori
Its interesting to see what happens to these bowlers when they tour Australia.
Effectiveness as Bowler : Wickets per test
I find this a very good criteria (not perfect as with any other) to determine the effectiveness of a bowler over his career. Thus Barnes with his 7 wickets per test makes him such a fantastically effective strike bowler. Murali is a very high 5 per wicket at this stage of his career. How does our reference group fare on this score.
Code:
[B]Type Career W/T Aust.W/T Diff W/T[/B]
LAS 3.27 3.20 -0.06
RAS 3.35 3.35 0.00
Both 3.30 3.28 -0.02
Note: The figures of Murali are removed from the above.
So, it can be seen that the bowlers as a whole do not fare much differently on this score in Australia in comparison to their overall careers. Within the groups there are variations of course with Tayfield (1.4), Bedi (1.0), Emburey (0.9) Iqbal Qasim (0.8) and Edmonds (0.5) taking much more wickets per test in Australia than all others.
Lock (-2.3), Blythe (-2.1) and Verity (-1.3) are the ones who suffer most in Australia on this score.
Murali has an amazing 6.12 wickets per test in his career as a whole and a mere 2.4 per test in Australia. Easily the worst in comparison. Even in absolute terms (without reference to creer stats, Murali comes 21st in this list of 27 bowlers in wickets per test in Australia and 11th amongst the 13 right hand off spinners.
I remind he has by far the highest number of wickets per test of any spinner in the history of th game
for his career as a whole. What Australia does to his figures is absolutely astonishing.
Not a great start for the Matthara Marauder, I am afraid in this report.
FINGER SPINNERS IN AUSTRALIA - Part 2
More precise measure of effectiveness - Strike Rate : Balls per Wicket
The wkts per test criteria is considered slightly less useful since a bowler may take more wickets by sheer number of overs bowled in a test match. Thus a team where one bowler is head and shoulders above the others, he could end up getting more wickets by default, as it were. Thus a better measure is balls per wicket.
Generally faster bowlers take fewer balls to get their wickets and those bringing the ball in to the batsmen tend to have lower strike rates than those that take them away. The second part of the above sentence is generally but not always true. Also the changes in the LBW rules over time have changed this equation too.
Murali has a fabulous career strike rate of 54.1 which is like a pace bowler's rather than a spinner's as can be seen from the strike rates of our reference group.
Code:
[B]Type Career SR Aust.SR Diff %[/B]
LAS 77.31 80.7 4.45
RAS 82.04 88.5 7.86
Both 79.51 84.7 6.58
Clearly the effectiveness (ability to strike) of all finger spinners drop slightly in Australia but the drop is not very significant. Bedi (-15.4%), Valentine (-12.4), Qasim (-11.4), Emburey and tayfield have better strike rates while Blythe (46.6), Verity (45.9), Illingworth (29.5), Peel and Titmus have a drop in ability to strike of between 25 and 50%. Once again, only Lock with a drop of 167% (SR of 202 in Aust. against 76 in career) suffers greatly.
Murali's drop is 142 percent. In absolute terms, Murali ranks 26th amongst the spinners in the reference group and last amongst the off spinners.
Its important to remember that for the career as a whole Murali ranks amongst the top three in strike rate. The other two being Blythe and Peel from a century ago with completely different statistical reference points. Thus effectively Murali has by far the finest strike rate of all spinners since the end of the first world war and yet he has the worst ever in Australia bar the unheralsed (relatively) Tony Lock.
The drop is dramatic once again.
Cost Effectiveness : Runs per Wicket
This is the most common criteria used to rank bowlers since it combines the strike rate with economy. It is a useful overall tool of measurement though the break up of strikeability and economy is better for deeper analysis.
Code:
[B]Type Career Avg Aust.Avg Diff %[/B]
LAS 29.1 31.9 9.68
RAS 30.0 33.3 10.99
Both 29.5 32.6 10.55
Once again there is a slight drop in performance for finger spinners in Australia but the drop is just about 10 percent. The average for the reference group goes up from 29-30 to 32-33. Clear drop but not alarming.
Emburey benefits most from bowling on Australian pitches with his average dropping ovr 16% (38.41 to 32.11) with Bedi having a very small (4.2%) improvement. Everyone else drops (Laker is about even). The worst affected are Blythe (57.6%), Verity (41.8), Illingworth (39.9), Doshi (30.2) and Peel (27). Clearly the English bowlers enjoy find the difference between the wet English summer and soft underground conditions a much bigger change to Australia.
But, once again, no one comes close to what happens to Murali. His average goes up a whopping 246 percent - from 21.78 overall to 75.42 in Australia. He again moves from 4th in the over all list (again with Blytrhe and Peel well above him and Laker more or less at par) to the absolute bottom of the heap.
Lock keeps him company once again but even he with his 194 percent increase, is not able to touch Murali's downfall down under.
