After a great win last night against against her idol Venus Williams, Tonight Madison Keys faces the biggest name in the biggest game of her young career: Serena Williams.

Keys suffered a leg injury before gutting out a win over former champion Venus, and it remains to be seen what physical condition she will be in tonight against her Number 1-ranked sister.

Shawn McCabe, who spent some time giving lessons to the Quad Cities' own Madison Keys said that even early on Madison showed a desire to play beyond her peers.

Instead of a sleepover to celebrate a birthday, she would want to go hit tennis balls again. She had a look about her, intensity that would last beyond the patience of other players her age. And her forehand? Her best feature, even as a junior. "She could hunt Sasquatch with that thing," McCabe said when asked for the one thing above all else that set her apart during the early years of working with her. Keys' averages a Tournament-high average 72 mph on her ground strokes.

Let's hope she brings that tonight, because Serena Williams is the biggest game Keys has had in her sights.

Literally. Good Luck Madison!
