Dick Savitt
In 1951, at the age of 24, he won both the Australian and Wimbledon men's singles championships. Savitt was mostly ranked world No. 2 the same year behind fellow amateur Frank Sedgman, though was declared world No. 1 by The New York Times and The Owosso Argus-Press following his Wimbledon victory. He retired the next year. Savitt is one of four American men who have won both the Australian and British Championships in one year, following Don Budge (1938) and preceding Jimmy Connors (1974) and Pete Sampras (1994 and 1997).
