Did anyone see that US Open Match?

I didn't see the Williams vs Schiavone match, but i did watch the highlights, and I think Williams is moving pretty well. 

She usually doesn't play solid players like a Schiavone first round, but i think Schiavone helped Williams get warmed up for the rest of the tournament. I think she's going to take it because of this match.

I think WIlliams and Sasha are working hard, do you think Williams will get 22 Majors?

PS what's up with Serena always shaking the referee hand before her opponent?

Here is the link if you guys would like to check it out.
