Cartwright began his county career as a teen-aged batsman who stroked the ball around with great style and aplomb but rarely seemed to beat the field.
Only when his medium paced bowling began to develop was he able to secure a guaranteed place and when he performed the "double" in 1962 batting and bowling were about equal. As swing and seam were continuously refined the bowling took top billing and by the time he took 147 wickets in 1967 the batting was regarded as "rugged and useful".
So complete a metamorhposis is rare but when his Warwickshire career was concluded 10781 runs, 1058 wickets saw the only Warwickshire all-rounder to add 1000 wickets to 1000 runs. In a handful of Tests he was useful. Here was the ideal county player.
