It is not correct to generalize and it is not factual that all women who play tennis are divas. You might as well say all male tennis players are egomaniacs. It is demonstrably false. There is much humility in tennis because the sport teaches you that winning depends on you alone and you cannot blame anyone else. Even in doubles it would be viewed as insufferably bad form, especially if your partner made most of the mistakes: maybe they were made because you set him up.
Serena Williams blamed no one but herself for bowing out in the fourth round of the Australian Open last week, snapping a breathtaking winning streak that included wins last year at Roland-Garros, Wimbledon, and Flushing Meadows, three of the four great tournaments. Everyone in the tennis world with a microphone or a typewriter said she was bound to win at Melbourne Park, giving her a Serena Slam, which is what tennis commentators have taken to calling four in a row but not in the same calendar year.
