Serena Williams in the Finals, USTA is Giddy

Serena Williams only need an hour-and-a-half to defeat Dinara Safina in straight sets 6-3, 6-2. Williams really just let Safina implode: the Russian had 41 unforced errors, and won only 29 percent of points off her second serve.

After the match, Venus Williams was waiting for her kid sister outside the women's locker room with Hank Kuehne. An absolutely elated Arlen Kantarian, the CEO of the USTA, strolled by and tapped Venus Williams arm and then began clapping his hands. He gave her a thumbs up, and smiled ear to ear.

It's the first time the USTA has been able to feature a Williams sister in the Open final since 2002.

And it looks like that primetime final will be even more primetime: If rain hits, there's a good chance that match will be on Sunday night at 9 p.m. on CBS.
