Roundarm bowling

In cricket, roundarm bowling is a style that was introduced in the first quarter of the 19th century and had largely superseded underarm bowling by the 1830s. Using a roundarm action, the bowler has his arm extended at about 90 degrees from his body at the point where he releases the ball. 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.
