I have read two excellent reviews of Mens/Womens US Open events at:
They agree substantially with each other and I am in strong agreement of the majority of the content of the articles. Rather than rewrite the content, please read the articles at the original source!
I've therfore had the following bets.
2.5 pts E/W Hewitt (33/1) (Mens US Open)
2 pts E/W Chakvetadze (33/1) (Womens US Open)
2.5 pts E/W Kuznetsova (25/1) (Womens US Open)
I've also had a 0.5 pts E/W double on each of Hewitt/Chakvetadze and Hewitt/Kuznetsova
