Venus Williams hails performance of Madison Keys

Venus Williams has praised Madison Keys, after the young player knocked her out of the Australian Open.

Venus was denied a semi-final match with her sister, Serena, after she went down 6-3 4-6 6-4 to her fellow American, and she said that her serving may have cost her the match.

She told reporters: "Yeah, I definitely didn't serve as consistently as I wanted to. You know, I felt like I was just not as aggressive off the ground as I would have liked. So I think in this kind of match you have to be aggressive.

"Like I said, I give a lot of credit to her because she really set her points up. She was swinging freely. Most of them went in for her. So it was just, you know, great for her."

Williams is expected to rise to either 11th or 12th in the world.
