First off I am new to tennis betting. But according to a couple of tutorials I read I presumed my wager to be good. I placed a bet for Zhang Shuai at Heritage and the line was -1.5 +180. She won a total of 16 games and A. Sasnovich won 11. I was told that I bet on # of sets won. So in other words the only way to win that bet is if Zhang Shuai won the first 2 sets? It was on the whole match and not a 1st set bet to confirm. What happened here? It looked like I won my other bets from similar circumstances.
