Venus and Serena Williams remain two of the worlds most dominent female tennis players after their impressive wins on Wendesday to advance to the third round of the US Open.

As expected, both Williams sisters are exhausted from their tuff play through out the year and they’re looking forward to a nice vacation after the US Open concludes.

“Wear and tear does put a lot on your body,” Venus Williams said. “It’s September now. I started literally in December. So I guess it’s not a huge surprise that at this time of the year things start to be a little sore and start to hurt.”

If both sisters continue to win they’ll likely face off against each other in the semifinals.
