Re: Has any player won a Singles and doubles of a slam?
Famous case: Bobby Riggs.
Of course, he's famous as having won the U.S. National Championship, (1939 & 1941, I think--when it was played at Forest Hills...)
But he won Wimby!
Riggs became famous as a hustler and gambler, when, in his 1949 autobiography, he wrote that he had made $105,000 in 1939 by betting on himself at Wimbledon to win all three championships: the singles, doubles, and mixed doubles. Betting is legal in England, and he parlayed a modest $500 initial bet on his chances of winning the singles competition into a sum that would be equivalent to at least $1 million in 2006 dollars. According to Riggs, World War II kept him from taking his winnings out of the country, so that by 1946, when the war had ended, he then had an even larger sum waiting for him in England, fattened by compounding interest.
