It is interesting that Billie Jean King missed out on a Calender Slam in 1972 because she didnt even play the Australian Open. This was her best ever year, she won all 3 grand slams she played- the French Open, Wimbledon, and the U.S Open, but bypassed Australia to start the year. She started by winning her only ever French Open, an amazing feat for her given her general mediocrity on clay. She defeated Evonne Goolgong, someone generally regarded as a far superior clay court player in the final. She regained her Wimbledon title by thumping Goolagong in the final, avenging a loss from the 1971 semis. She then won the U.S Open to wrap up the year. I wonder how much she regrets not playing the Australian Open now in hindsight, or how likely she would have played it if she would have known how her year would have turned out. This is an interesting quote from King on encyclopdia: http://en.wikipedia.org/wiki/Billie_Jean_King For the record Virginia Wade won that 1972 Australian Open with a win over Evonne Goolagong in the final. King's lifetime head to head with Wade is is 22-9. Not a gaurantee of course. Wade despite being overshadowed by Court, King, Evert, Navratilova, and Goolagong throughout her career is still a great player who can beat any of the big guns at any given moment. However you would still have to surmise her chances were pretty good, especialy in the form she obviously was in during her best year ever.
