The statistics are daunting to say the least. Since 2000, the Wimbledon Women Singles title has been a toss-up between sisters Serena and Venus. Venus has won it five times, Serena four. And they have only allowed two other women to win the title - Maria Sharapova in 2004 and Amelie Mauresmo in 2006. To add to their dominance, they have made it an all-Williams final in -02, '03, '08 and '09.
Can they do it again this year? Well, they haven't really played the rest of the year so in a way, they are 'rusty' and they have been defeated by some top players in Eastbourne last week - Serena by Vera Zvonareva, and Venus by Daniela Hantuchova - both in 3 very tight sets.
However, the scoreline shows that they still have what it takes to win and in Wimbledon, when the whole world is watching, the two sisters just rise to the occasion! So, there is a 50% chance for them to really make it another Williams finals.
Serena's major opponents may likely be current French Open champion Li Na and Wimbledon rival, Maria Sharapova. She may have to defeat both if she wants to reach the final.
Venus, on the other hand, may have Vera Zvonareva and Petra Kvitova to defeat, if she wants a finals berth - and both Vera and Petra already have Wimbledon credentials - Vera, a finalist here last year, while Petra was a semifinalist, so they're not exactly greenhorns in this surface anymore.
Anyhow, it's always an interesting Grand Slam when these two tigresses are here. Up to now, they are still the barometer of women's tennis since the current world #1 Caroline Wozniacki has not exactly held herself up on these big occasions.
