Boxing Day Test analysis using Impact Index

Happy New Year 2012 to all Cricket Lovers

First of all i will give you all people a brief introduction to Impact Index as to how it is calculated.Jaideep Verma is the creator of Impact Index

 I have been associated since May 2011.

source : Impact Index Methodology

Impact Index, unlike every other cricket statistical system in the world, is completely transparent in its workings. It is possible to do all these calculations manually too, at the back of an envelope, once the system is understood. However, to save time and energy, we have automated the entire system and are in the process of running all cricket data through it.
A simplified step-by-step list of its mechanism is given below, in case you want to understand how it really works. This methodology is for limited over matches.
1) Based on the innings totals, a base figure is generated for the match. This is measured in runs, for all players (batsmen and bowlers and wicket-keepers).
2) Every performance in the match is thereafter measured against this base figure (as a ratio). One IMPACTpoint is procured when the performance is equal to the base. That is seen as merely the par performance for the match.
3) For a batsman, IMPACT points are garnered for a) Runs Tally b) Strike Rate c) Pressure d) Chasing and staying not out in the second innings. e) Partnership-Building.
4) The Strike Rate IMPACT can go into negative or positive depending on his strike rate vis-à-vis the base strike rate in the match.
5) The Pressure IMPACT only measures pressure that comes from fall of wickets. It kicks in when a batsman comes in to bat in a tough situation (as defined from how many wickets have fallen) and crosses the base runs. Tough situations are defined as per the base runs.
6) For a bowler, IMPACT points are garnered for
a) Wickets (the top 7 wickets and the last 3 have different values, in most cases, as per the circumstances of the match)
b) the Economy Rate (again, calculated against the base economy rate of the match - in T20 matches, the economy rate has a slightly higher value, as per the circumstances of the match) 
c) Breaking Partnerships (its limit is set by using a multiple of the base) d) Building Pressure (taking quick wickets within the base).
7) Catches, stumpings and credited run-outs all get extra / IMPACT points (a fraction of the base). The winning captain also gets an addition to his IMPACT (again, a fraction of the base). Wicket-keepers get flat points for doing an assigned job.
8) All the above points are measured against the base figure, and are therefore ratios of the base in some way (which is fundamentally why they are measurements and not ratings).



Given below are the overall Impact Index of the players on the scale of 0-5 (only exceptional performance sometimes go above 5). The green tick symbol () signifies awesome performers while the red cross( × ) signifies the below par performers for the test match. Yellow exclamation (!) means Average performance in comparison to the top performers.


We all know that the key contributors for Australia in the Match were Ricky Ponting,Michael Hussey, James Pattinson, Ben Hilfenhaus and Peter Siddle while for India it was just the duo of Zaheer Khan and Umesh Yadav. It was after a long time it was seen that two of its fast bowlers were the major contributors to the what could have been a well fought victory if the at least 2 of its batsmen performed as well as they had done in this match.

Ben Hilfenhaus score of 5.79 showed that he deserved the Man of the match award ahead of Pattinson. Another reason behind that was the fact that Hilfenhaus had not played for Australia since Ashes last year and  to be the main reason behind Indians losing their last 8 wickets for just 68 runs. Pattinson score of 5.18 was also helped by his knock of 37 not out in the 2nd Innings which helped Aussies build a lead which was tricky to chase down on the pitch which was assisting fast bowlers. Though Pattinson really bowled well in the final innings when his fiery pace bowling softened the master blaster a bit which then resulted in the master giving away his wicket to a wide delivery from Siddle. Ricky Ponting scored twin sixties with the 2nd Innings score being significant because of the state of play he came at while Aussies were reeling with pressure at 2/17 then soon at 27/4 and then he built a partnership with Hussey whose 89 was the highest impact innings (3.5 out of 3.88 came from his knock) of the match.

Umesh Yadav was the best performer with a score of 5.42 from the Indian side attributing to the 7 wickets he took in the 2 innings. He was fiery keeping up his pace throughout the match. He got pressure building points during both the innings as he was responsible for taking quick top order wickets. Zaheer also added 7 wickets to his name which resulted in a score of 5.15. It was an exceptional performance considering that he had returned straight from an Injury after a long break of 4 months without any practice behind him with just a 2 first class matches and the tour opening practice game.

As i said earlier if any 2 of the batsmen (say Sachin and Sehwag) performed and scored while chasing it would have meant with India would have won the MCG test after 30 years since the last time they won here.
A positive start from Sehwag like the one he did in the Chennai test against England when he scored a quickfire 83 of just 68 balls which resulted in India chasing down a stiff target of 387 very easily would have helped a lot.

There were a lot of below par performances from both the teams with the worst performance coming from the new off-spinner Lyon who just took a solitary wicket in the match. Shaun Marsh's return from injury was not very good as was Laxman's and Virat's performance in the match. Ishant's bowled really well in the first innings but luck did not favor him at all and he went wicket-less.

The wicket keepers Dhoni and Haddin both performed well behind the stumps but did not contribute well with the bat.

Hope you guys like the section and will keep updating the post match analysis like this for the SCG test after its over. Will continue with my end of day reviews too for the SCG test where everybody is waiting for Sachin who averages an astounding 221 at this venue will try to complete his 100th Ton in the 100th Test at SCG which will be an icing on a cake for all the cricket lovers.

Till tomorrow
Bye
