Here is a list of slow bowlers who have bowled more than 80 overs in Tests in the last 12 months (excluding matches involving the Bangles and Zims):
Code:
Bowler W Ave SR
Kartik 14 21.43 55.50
Gayle 18 24.89 65.78
Harbhajan 44 25.98 55.82
Jayasuriya 12 26.17 73.08
Warne 66 26.26 53.83
Giles 42 30.00 62.86
Herath 17 30.18 64.12
Kumble 54 30.93 61.70
Kaneria 49 31.00 58.94
Sarwan 8 33.50 69.00
Afridi 8 35.63 69.50
Vettori 22 42.86 86.23
Chandana 15 45.13 71.47
Banks 9 53.11 82.67
Boje 21 58.00 109.90
Wiseman 6 80.67 154.50
In that period, Giles has bowled on pitches which will mostly resemble the ones he bowls on this summer. Warne and Harbhajan clearly have better figures, but Giles's are very comparable with Kumble's and Kaneria's, with slightly lower average but slightly worse strike rate.
I would suggest that Giles's bowling has taken a big leap forward in the last 12-18 months, in that he now bowls at least competently nearly all the time, whereas in 2003 and before he was only effective on helpful pitches and was often a joke on unhelpful ones.
Those who get their jollies quoting career averages all the time will no doubt have an explanation why people should be interested in Giles's figures from 2002 (or whenever) when considering what sort of bowler Giles is today, but it seems to me that the above figures are a bit more relevant to the discussion.
