Serena Williams is pursing a Grand Slam. A Grand Slam is when a player wins the Australian Open, French Open, Wimbledon, and U.S. Open. The last time someone won a Grand Slam was Steffi Graf in 1988.
Serena is a dominate athlete in her sport that we wonder why she has not won Grand Slams in the past. With a career record of winning over 730 singles, 22 doubles, 69 single titles, and has a winning percentage of 88% at grand slams and 85% in all other top matches. You would think that she would have gotten plenty of grand slams over the years. This year she is ranked number 1, has came out on top in three opens, and there is only the U.S. open that she has yet to overcome.
