At 17 Errol Draper followed his elder brother Ron into the Eastern Province team in the 1951-52 season, taking 6 for 114 in the first innings of his debut match.

His best seasons were 1954-55 (407 runs at an average of 37.00) and 1955-56 (435 at 39.54), but he remained a regular member of the team until 1967-68, when he made his highest score, 118 against Orange Free State, his third century against Orange Free State in his final first-class match. He captained Griqualand West in 1959-60 and from 1962-63 to 1967-68.
