Miller is hoping to hit the jackpot in the Joshua stakes but knew that anything other than an impressive victory over former Deontay Wilder victim Duhaupus would end his chances.
But, having been told by promoter Eddie Hearn that he could get a chance to face Joshua as early as this summer, the self-styled ‘Big Baby’ kept up his side of the deal with a wide unanimous decision against the Frenchman.
The victory, which was the first time 21-0-1 (18) Miller had ever gone the full 12 rounds, was an eliminator for AJ’s WBA title and the American wasted no time in calling out the unified heavyweight champion.
He said: “Anthony ‘G-String’ Joshua should come and get this work – all day.
“I’m ready to toast that English muffin. We cooked French fries tonight [Duhaupas] so it’s English muffins next time.
“It’s like I said before, Eddie Hearn has made promises and comments to other fights but let’s get this straight, I’m not signed with Matchroom boxing and Eddie Hearn.
“I am my own boss, I have Big Baby Promotions, but it was decided that it would be in my best interests to fight on an Eddie Hearn card to build my profile.
“Of course we want the AJ fight. Eddie Hearn has been talking a lot that AJ is going to come to Brooklyn, do this and do that.
“I’m not going to get on my knees and beg, us New Yorkers work hard to earn our shot.
“But if you bring him to New York I will bust his behind. If not, we have Manuel Charr in Germany and we could probably make that happen.
“So that’s my next best option if Eddie doesn’t put his money where his mouth is and make it happen.
“He’s not going to sell me the dream like he did with Luis Ortiz and Dillian Whyte and all the others guys.”
Hearn, meanwhile, confirmed that Miller is very much in the picture for a shot at Joshua should the continuing Wilder saga not reach a fruitful conclusion.
He said: “If we can’t get Wilder, Miller is definitely an option.
“You’ve got Miller, Alexander Povetkin and Wilder there. We will have to see.
“But if Anthony is going to come to America [to fight] and it’s not against Wilder, we want to come to the Barclays Center and the guy to do it against is Jarrell Miller.
“We’ll see over the next few weeks. The WBA have called a mandatory but we could ask for an exception to fight Miller.”
