Why is anyone shocked Serena and Venus or Li Na lost ? Serena is 32 and Venus is even more ancient she is almost 34! Li Na is 32! In pro tennis these ladies are ancient they are all amazing champions but they are old! Where are the young women of colour who will take over their place when they retire? We need more black and Asian women to step up and become champions. Li Na and the Williams Sisters make women tennis so interesting by bringing in new audiences. I will miss these ladies when they decide to retire. The Williams Sisters are legends of the game but people commenting here are silly. As tennis players get older they have more off days. Serena also appears to be tired of the grind of the WTA tour. Serena has been a tennis pro since 1997! Both sisters have had long careers they along with Li Na deserve our respect as women of colour who diversified the game.
