John Roderick Siedle (29 January 1932 – 2 August 2008) was a South African who played first-class cricket for Western Province and Natal between 1955–56 and 1957–58.[1] He was born and died in Durban, KwaZulu Natal, South Africa. He was the son of South African Test cricketer Jack Siedle and nephew to Karl Siedle.
A right-handed middle-order batsman, John Siedle's first-class career began with an innings of 127 for Western Province against Eastern Province on New Year's Day 1956.[2] Though he had limited success after that, he retained his place in the Western Province side for the rest of the 1955–56 season. But there was only a single game in 1956–57 and the following year he turned out for Natal in two first-class matches. In the second of these, his final game, he opened the innings and scored 81 against Orange Free State.[3]
