As Monday dawns in New York City Serena Williams is going for a calendar Grand Slam. Don't be fooled by her dominance -- this is not an easy feat. Think about it for a second. The first year that all four majors were played by women was 1922. Since that time only three women, Maureen Connolly Brinker (1953), Margaret Court (1970) and Steffi Graf (1988) have won all four slams in the same year. Only three women. If Serena triumphs in two weeks, she will be the fourth.
