Roundarm bowling

In cricket, roundarm bowling is a bowling style that was introduced in the first quarter of the 19th century and largely superseded underarm bowling by the 1830s. Using a roundarm action, the bowlers extend their arm about 90 degrees from their body at the point where they release 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.
