Pretty easy to work out. It just depends on how the bet options was phrased. If it was an over/under (ie 9.5 rounds), well the fight lasted under 9.5 rounds so that is the winning bet. If it was a prop bet with the language set as "Will the fight go the distance? Y/N" - the scheduled distance was 12 rounds, so the winning answer is "No". If it was a matter of "Bradley on points", then yes you ought to have won because that's what happened. A TD is a point win same as a UD, MD, or SD.
