Bramble was not supposed to beat Mancini.

And then people were stunned when Rosario KO'd Bramble like he did.

I'm not saying it's the biggest but it is one of them. Singer was seen as a contender but punching power was not necessarily his best attribute. Mandell on the other had been a durable champion who had defended the title against Canzoneri and McLarnin. It was definitely not expected that Singer would flatten him in a round, only to later receive the same fate against Tony Canzoneri.
