Career
Twentyman-Jones played for Western Province from 1898 to 1905 as a right-handed batsman. He scored 33 and 50 (out of a total of just 80) against the touring Australian cricket team on a bad pitch and was picked for the third Test match at Cape Town. But he was dismissed without scoring in both innings.
Twentyman-Jones also played rugby union for Western Province and South Africa as a wing.
He played in three international matches for his country, all part of the 1896 British Isles tour of South Africa. Twentyman-Jones scored his first and only international try in the Third Test at Kimberley, though the South Africans lost the game 3-9.
His final international was the Final Test of the tour, which saw the very first South African international victory, beating the tourists 5-0. Qualifying as a lawyer in 1898, Twentyman-Jones was appointed a judge in 1926 and had a prominent career in criminal cases.
He was also a prominent sports administrator.
