Ruiz has the higher confidence in this rematch since he already stopped AJ on their first encounter. And this is an immediate rematch. AJ dared without a break nor tune ups which is very risky career wise. But I don't think AJ quit on their first encounter. It was the referee that stopped it.
Boxing is an art and Andy Ruiz got the better of Anthony Joshua in the first fight and there were reports that Anthony Joshua got knocked out in the gym while training for the Andy Ruiz fight and he was concussed coming into the main event and since it was his debut here in the US he was having panic attack in the back stage before coming to the ring and now he has a loss in his career and i am expecting him to fight better in this fight as it will be a career changing rematch and one more defeat will end the hype he created.
That first fight served as a wake up call for AJ to be not over confident and not over looked opponents. Ruiz is a substitute opponent for AJ since Miller failed the drug test, that may also be the reason why AJ is over confident that he could beat Ruiz.
The first few rounds of the fight belongs to Joshua, in the third round, that's where the misery begins for AJ when he's trying to go for the kill when Ruiz was knock down and he's the one being hit by that short and crispy punch that put him in the canvass. I could not say that Ruiz is superior in the first fight, it's just that AJ was careless. Anyways, if AJ would still lose this rematch, his boxing career is over.
But still i am betting for AJ to win this one.
If you bet on AJ to win the fight whether through decision or KO, you will only get 1.44 odds, I think that's too cheap.
Maybe you'll consider betting on AJ to win via decision @ 5.40 because he might not be too confident in this fight trying to knock out the champ, maybe he will just use his length and consistently score throughout the 12 rounds.
