the only american book you can even sniff a chance at success at this sport is 5dimes.
If you do statistics properly, situations properly, you can make money. It's up there with baseball. The problem is it is very easy to chase with large favorites (-200-300) that go down and put a hole in your wallet.
I faded Serina Williams about 3 or 4 years ago in one of the majors opening rounds.
The player I bet on (dont remember her name was +2600.
Had 50 on it.
My bet got up 2 sets to none and I was going crazy.
Then Serina came back and won.
I still think about that every once in a while.
