Australia's bowling attack was led by Lindwall and Miller, who took the new ball in the Tests. Bradman used the pair in short and fiery bursts with the new ball. English cricket administrators had agreed to make a new ball available every 55 overs; at the time, the norm was to allow a new ball for every 200 runs scored, something that usually took longer than 55 overs. The new regulation played directly into the hands of the Australians, as a new ball is ideal for fast bowling and the tourists had a vastly superior pace attack. Bradman thus wanted to preserve his two first-choice pacemen for a vigorous attack on the English batsmen every 55 overs. As a result, Australia's third fast bowler Bill Johnston bowled the most overs, and the left arm seamer Ernie Toshack also had a heavy workload until a knee injury ended his campaign.
