Overarm Bowling Revolution Explained: Why Round-Arm and Then Overarm Replaced Underarm Cricket
The evolution of bowling in cricket from underarm (rolled along the ground) to round-arm (elbow at shoulder height, late 18th century) to overarm (fully above the shoulder, 1864 when the MCC legalised it). The stories: Christina Willes and round-arm bowling (her wide crinoline skirt), the 1981 Australia-NZ underarm controversy, and why the law changes transformed the balance between batting and bowling.
Cricket's bowling laws have changed three times in the sport's formal history — from underarm to round-arm to overarm — each change driven by a desire to restore balance between batting and bowling as batsmen adapted to the existing delivery method. Modern overarm bowling (the current legal method, legalised in 1864) generates speeds of 140-160 km/h that would have been impossible with underarm or round-arm deliveries. The evolution of bowling is central to understanding how cricket became the high-skill, high-speed sport it is today.
Underarm Bowling: The Original Method
Underarm bowling in cricket's early history: (1) Method: the bowler delivered the ball by rolling or bowling it along the ground (or releasing it below the waist at low speeds). The ball was pitched (bounced) at the batsman; (2) Batsmen's adaptation: as early as the 1770s-1800s, batsmen (using heavy, curved bats) learned to keep the ball along the ground by covering the forward-defensive shot. The underarm delivery was slow enough for batsmen to play it safely; (3) The response: bowlers needed to get the ball up to a height that forced batsmen to play differently — rolling underarm deliveries were easily defended. The push toward higher-delivery bowling was the bowlers' response to batsmen's dominance; (4) The last underarm in international cricket: the 1981 Australia-NZ underarm incident (Melbourne, February 1, 1981). Australia needed to prevent NZ scoring 6 off the final ball to tie. Australian captain Greg Chappell instructed his brother Trevor Chappell to bowl the final ball underarm (along the ground) — NZ batsman Brian McKechnie could not hit 6 from a ball rolling along the ground. NZ could not score; Australia won. The act was legal at the time in Australian domestic cricket conditions (but immediately banned by the MCC after the incident). New Zealand Prime Minister Robert Muldoon described it as 'appropriate that New Zealand was beaten by an Australian act of cowardice'.
Round-Arm: The Willes Revolution
Round-arm bowling's origin and legalisation: (1) Christina Willes (approximately 1807): the popular story of round-arm bowling's origin — Christina Willes, bowling to her brother John Willes in their family garden, found her wide crinoline skirt made underarm bowling physically impossible. She bowled with her arm swinging in a round-arm motion (arm at shoulder height). John Willes was reportedly so impressed with the delivery's effectiveness that he began bowling round-arm himself; (2) John Willes's attempt (1822): Willes bowled round-arm in a match at Lord's (1822). The umpire no-balled him. Willes threw his ball down, mounted his horse, and rode away in protest. The story is among cricket's most dramatic acts of individual protest against the laws; (3) The legalisation debate: the MCC debated round-arm bowling through the 1820s. Initially illegal; in 1828, a law change allowed the hand to rise as high as the shoulder. Round-arm bowling spread quickly because it allowed bowlers to generate more pace and bounce than underarm delivery; (4) Full round-arm legal (1835): by 1835, the MCC formally allowed the arm to reach the elbow at shoulder level. The transition to overarm came next.
The 1981 Underarm Incident: Cricket's Lowest Moment
The Greg Chappell underarm incident (February 1, 1981): (1) Context: Australia vs New Zealand, 3rd final of the World Series Cup triangular tournament (Australia, NZ, India). Australia needed to win to secure the title; a tie would send it to a further game. NZ needed 6 off the final ball to tie (a 6 would force a super over equivalent); (2) Greg Chappell's decision: Australia's captain Greg Chappell instructed his brother Trevor Chappell to bowl the final ball underarm — along the ground. Underarm bowling was legal in Australian domestic conditions at the time (the MCC Laws of Cricket did not specifically forbid it in 1981, though it was considered contrary to the spirit of the game); (3) The aftermath: the incident caused enormous public and political outrage. New Zealand PM Robert Muldoon called it 'an act of cowardice'; Australian PM Malcolm Fraser said 'it was contrary to the traditions of the game.' The MCC subsequently passed a law specifically forbidding underarm bowling in international cricket (it had not been formally needed before, as underarm had simply fallen out of use); (4) The Chappell brothers: Greg Chappell (Australia captain, born August 7, 1948) was one of Australia's greatest batsmen. The underarm incident became the defining negative moment of his captaincy legacy — widely remembered even 40+ years later as cricket's most infamous act of gamesmanship.
Frequently asked questions
When was overarm bowling made legal in cricket?
Overarm bowling was formally legalised by the MCC in 1864 — allowing the arm to be raised fully above the shoulder at the point of delivery. The evolution was gradual: underarm bowling was the original method; round-arm bowling (arm at shoulder height) was legalised in 1828-1835; overarm was the final stage in 1864. The overarm revolution transformed cricket — producing faster, higher-bouncing deliveries that required new batting techniques and protective equipment. WG Grace was the dominant figure of the early overarm era.
What was the 1981 underarm incident in cricket?
The 1981 underarm incident (February 1, Melbourne) was one of cricket's most infamous moments: Australia vs New Zealand, final ball of a World Series Cup match. NZ needed 6 off the last ball to tie. Australian captain Greg Chappell instructed his brother Trevor Chappell to bowl the final ball underarm (along the ground) — making it physically impossible for NZ batsman Brian McKechnie to hit a 6. It was technically legal at the time but immediately condemned as contrary to the spirit of cricket. The MCC subsequently banned underarm bowling in international cricket. New Zealand's PM called it 'an act of cowardice.'
Why did bowling change from underarm to overarm?
Bowling evolved from underarm to round-arm to overarm because batsmen progressively mastered the existing delivery method, creating a need for bowlers to find new ways to take wickets. Underarm bowling was easy for batsmen to defend (the ball came slowly and predictably). Round-arm (arm at shoulder height) allowed more pace and bounce. Overarm (full shoulder height, 1864) allowed maximum pace and bounce. Each change was initially controversial (traditionalists objected) but eventually accepted because it restored the balance between bat and ball that had tilted too far in one direction.
