Kramer's 1948 world pro championship tour victory would be the final occasion in the pre-open era that a first year professional player would win a world championship pro tour. However, some new professionals had solid achievements in their first year on the pro circuit, Gonzales winning the U.S. Pro Indoor over Kramer in 1950, Sedgman achieving a world No. 1 pro ranking in 1953, Trabert winning at Roland Garros in 1956, Hoad winning the Australian subtour in 1958, Rosewall in 1957 and Anderson in 1959 winning at Wembley.
