TUCSON, Ariz. - Undefeated heavyweight prospect Jarrell “Big Baby” Miller floored Donovan Dennis twice in a thoroughly dominating seventh round TKO (2:31) in the ShoBox co-feature.

Miller (16-0-1, 14 KOs), who went past the sixth round for the first time in his career, landed 52 percent of his power shots.  The Brooklyn native scored two knockdowns in the first round – the first with a devastating looping right, the second with a straight to the chest – and had Dennis nearly out on his feet in what looked like a certain first-round finish.

The southpaw Dennis (14-4, 11 KOs) somehow survived the round and actually pushed Miller into uncharted waters.  Dennis had some moments where he out boxed his opponent, but Miller’s power and size – a 56 pound weight advantage – was the deciding difference.   Dennis was breathing through his mouth and gasping for air when referee Tony Zaino wisely halted the contest as “Big Baby” teed-off on his defenseless opponent.

“I had him out in the first round, but I threw my shoulder out throwing a left hook,” Miller said.  “I was looking for the knockout so bad he started catching me with some shots.  So then I decided to box a little bit and that’s what I did until the knockout came.

“I’m glad it went seven rounds.  It taught me to go to Plan B.  I can box beautifully when I want and I showed some of that tonight.  It was good experience.  My power was there; my wind was good. I was breathing well and seeing the shots.”

After the fight, Miller called out the two American heavyweight world champions.

“Charles Martin, I’m coming for you.  Deontay Wilder, I’m coming for your Alabama BBQ.”

In the locker room after the bout, Dennis admitted that he was surprised by Miller’s boxing ability:  “He’s a better boxer than I thought he would be. That surprised me.”
