fellas not much value here as Serena is at -600, BUT for those of us still looking to invest in this low reward wager, who are you on why, why not. Also, I feel Serena Wins easy, Rad has not played against anyone with the serve (24 aces against Azaranka) she posses. If for some miracle of happens and it goes 3, Serena will have no issue wearing her out.
