Some people are still divided about his split decision win, but odds on him are simply amazing for this fight as a underdog and I have to take it.
I know Sterling is favorite in this fight, but O'Malley is few years younger, he has small reach advantage, and great KO record.
For more risky bet I would also try O'Malley to win by KO or TKO.
O’Malley is an UFC created fighter and a record. It is a fact that the kid has a talent, but UFC gave him weak opponents imho. I have started no liking Sterling when he got the belt after illegal knee. But in next fights he managed to change my attitude to him. 4th title defence. That is a lot. A lot of guys lose belts after first defence. Imho Sterling will wrestle O’Malley in parter till UD or split win.
