Taking Timea Babos at odds of +170 wouldn't classify as "longshot", but I like your sense of dramatics, it builds suspense.
Kimiko Date Krumm is a bad-ass. It is always tough to go against her, she's 89 years old but she fights like hell. With that said never a bad idea to take a chick at 2.70 odds when she's playing somebody that is almost 90 years old.
