The sisters Venus and Serena Williams will be measured on  Wednesday in a key match in the Open Tennis USA, which will be the fourth  between the two duel in the history of the tournament, a tradition at this  stage or special dish in the letter in Flushing Meadows.   The Williams account for 15 Grand Slam titles and four U.S. Open, and on  Wednesday will define one of the tickets to the semifinals of the last major  tournament of the season.
If the forecasts of some malicious not fail, should Venus Williams beat her  sister Serena when confronted in the quarterfinals of the U.S. Open.
Those who bet on this asset will argue that thus the largest of the sisters  equate the account number of Grand Slam titles won.
Serena steals eight scrolls adults: Three in the Australia Open (2003, 2005,  2007), one at Roland Garros (2002), two at Wimbledon (2002, 2003) and two U.S.  Open (1999, 2002).
Venus, one year more, was titled five times in the cathedral of tennis,  Wimbledon (2000, 2001, 2005, 2007, 2008) and two in the walkway in Flushing  Meadows (2000, 2001).
Some suspicious minds think that the sisters take turns to win in the  tournament. If so, then it's up to Serena take the prize in this Open New  Yorker, because this year and was titled Venus at Wimbledon.
"If I had a sister who were not so good, then I could win easily, but she  is very good, and is playing well," said Venus.
The record between the two is tied to eight victories by side, with division  honors this year.
Serena won the tournament fast track in Bangalore (India), and two months ago  Venus took revenge in the finals of Wimbledon (7-5, 6-4).
"We always say that going to win the least wrong, we know a lot, and every  one knows what to expect from the other," said Serena.
Another factor is that the smallest of the sisters could become the world  number one if you win the Open Flushing Meadows, following the collapse of the  current tenant of the plaza in this contest, serbia Ana Ivanovic.
"For now I do not think about that. Only I think my next opponent will be  someone who is called Venus Williams, and that's what worries me,"  confessed Serena.
Both sisters have won just over $ 20 million each since they became  professional, Venus and Serena in 1994, one year later.
Much of those revenues have come from the U.S. Open, especially those that  generate advertising contracts before, during and after the tournament.
Winning the U.S. Open is also an issue for them business.
In breaks from tennis, Venus serves its interior design company "V Starr  Interiors" and its line of designer clothes, called elevators.
Serena spends his spare time to surpevisar and give ideas to its own brand of  clothing, aneroid (his name upside down), which already is sold in exclusive  boutiques in New York and Los Angeles.
Winning the Grand Slam last year in New York for Williams is more than lifting  the Champions Cup or enter the cheque of a million dollars in its accounts.
This is turning into a gateway Flushing Meadows where 'fashion' and tennis go  hand in hand, the real secret of success of the Mark Williams.
