Serena vs Venus Williams in #quarterfinal2015, #usopen2015,

Who knows what history has in store for us on Day 9 at the US Open, where Venus and Serena will face off for the 27th time in their storied careers. 

Serena comes in holding a 15-11 advantage. “It's been an amazing rivalry,” said Serena, who is a Slam away from equaling Steffi Graf’s Open era output of 22 majors. 
“It means a lot. We've done a lot for the sport. Hopefully, it can continue as long as we play.” She added, “I think it's more fun than it used to be. We really relish the opportunity. We're both happy to still be involved in getting so far. And it's still super intense. 
She's doing well and she wants to win this. So do I. It's not easy.”
