Rodney Craig Ontong (born 9 September 1955) is a former first-class cricketer who played for Glamorgan County Cricket Club in the UK, and for various South African teams. Ontong was born in Johannesburg, and originally came to the UK from South Africa to pursue a football career; he had trials with Chelsea in the early 1970s. He did not impress enough to join their books, instead turning to cricket, after some success as a club cricketer in London. The South African earned a place on the MCC groundstaff and coach Len Muncer later recommended him to Glamorgan, Muncer's former county. Ontong made his Glamorgan debut against the touring Australian team at Swansea in 1975. From 1977 he was a regular in the Glamorgan side and would return to South Africa at the conclusion of each British summer
