from the ACS cricket archive (was not allowed to post the links):
Marshall's stats for Hampshire:
210 matches
5847 runs at 25.20, 5 100s, 26 50s, 76 catches
826 wickets at 18.64, 45 5WI, 7 10WM
Hadlee's stats for Notts:
148 matches
5854 runs at 38.76, 11 100s, 29 50s, 105 catches
622 wickets at 14.51, 38 5WI, 5 10WM
The green tops at Notts would have helped Hadlee's bowling average but not his batting average.
This is what stood out for me: Marshall and Hadlee scored almost exactly the same number of runs for their counties, 5847 versus 5854, Hadlee winning by just 7 runs!!!
