Serena Williams may have recently defeated Venus during the third round of this year's US Open, but it's clear the sisters have nothing but love and respect for one another. Serena and Venus have been competing against each other for the past 20 years, and their bond only seems to grow stronger with time. "I always want the best for Serena," Venus previously told Oprah Winfrey. "As the older sister who took care of her, I still look out for Serena on the court — yet I'm trying to get the win myself. We're definitely in a strange situation, one that no other player has been in. The best part is that right now we're the best at what we do." Win or lose, at least Serena and Venus can always count on each other.
