Okay i just want to say this to community of this betting site that the Tennis retirement on this site is soooo ridiculous. So your guy won the first set but in the second set he got injury and he retire from the match your bet is considered to be lost....wow i think this is the only betting site in the world that has this rule like this... it is so unfair rule and manipulated..cause only you can know that is when you lost, and that is so bad for a big betting site like this one... if someone is retired it should be void all the way, gentlemans from the unibet!!!!
