2015 Williams Watch- All Eyes On Serena

The 135th edition of the US Open kicks off today and runs through September 13, and there's something new for this event.   As part of a $500 million renovation,  a roof is being constructed that will cover Arthur Ashe Stadium that is scheduled for completion in time for next year's open.

That's the future along with a planned roof for Louis Armstrong Stadium and a 8000 seat Grandstand Court, so now let's talk about the present and the historic opportunity that presents itself for her.

Serena walks onto the USTA Billie Jean King National Tennis Center grounds in NYC as not only the world's number one ranked player and number one seed in this tournament, but a favorite to take the women's title.  Big Sis Venus is seeded 23rd.

If she does so, it will not only be her fourth straight US Open title, but her fifth straight Grand Slam and as every tennis fan on the planet knows, her first calendar year Grand Slam.  And oh yeah, she would tie Steffi Graf with 22 career Grand Slam tournament titles.

But the road to tennis history starts with this first round match against Vitalia Diatchenko while Venus faces off against Puerto Rico's Monica Puig.
