Roundarm fell into decline after 1864 when the current style of overarm bowling was legalised, although W. G. Grace continued to use it to the end of his career.
The spread of roundarm in the 1820s was a natural reaction to the growing predominance of batsmen over the age-old underarm style of bowling.
The story goes that when bowling to her brother in the garden at home in the 1800s, Willes found herself inconvenienced by her large, lead-weighted dress which prevented her from performing the underarm action.
Walker worked out that he could generate more bounce and variation of pace if he bowled with his arm away from his body and soon realised that these deliveries gave the batsman added problems.
Being no-balled on this occasion was the final straw, for Willes reportedly threw the ball away and withdrew from the match, literally going straight to his horse and riding away.
Their success owed much to the prowess of two top-class bowlers William Lillywhite and Jem Broadbridge, both of whom were champions of the roundarm style, when they could get away with it.
In 1828, following the Sussex v England roundarm trials, MCC modified Rule 10 to permit the bowler's hand to be raised as high as the elbow.
Prominent roundarm bowlers to succeed Lillywhite and Broadbridge were Alfred Mynn, John Jackson and W. G. Grace.
