Batsmen's highest / lowest / final averages
With the recent reductions in Tendulkar's, Ponting's, and Jayawardene's averages in particular, I was thinking about batsmen's highest averages and how they compared with the final averages they ended up with (Hussey has retired on a high note, but he also is one with a bit of a contrast between his peak average and his final). Ponting was up around 57 at some point wasn't he?
I was wondering if anyone out there has an innings-by-innings record for the top 100 or so batsmen, and could easily put together a table containing :
final (or current) average;
final (or current) no. tests;
no. tests after which highest average achieved;
no. tests after which lowest average achieved.
The highest or lowest averages must be 20+ tests - I'm not interested in someone like Gooch whose lowest average was zero after his first test, or Michael Clarke whose highest average would be after his first test I think thanks to a century on debut... though I expect many players (eg Kallis) will have increased their averages since the 20 test mark, so that will be their lowest. And a rare few (Jimmy Adams, Mike Hussey) peaked before 20 tests and so that will probably be their highest averages for the purposes of this exercise.
Just something which interested me. Thanks to anyone who can help.
