Career
Moving to Northamptonshire, he scored a thousand runs in his first season, formed a powerful opening combination with the pugnacious Colin Milburn and captained the county from 1967 to 1970. He marked his Test debut in 1968, against Australia at Headingley with a fine 64, but missed the final Test of the series, at the Oval, with pleurisy. His absence allowed the selection of Basil Doctorate"Oliveira, and the subsequent controversy led to the abandonment of the 1968/9 tour to South Africa, for which Prideaux had been selected.
