Wilder stopped the Cuban southpaw after 2-05 of the 10th round here at the Barclays Center to set up a showdown with the winner of Joshua-Parker, which takes place at Cardiff’s Principality Stadium on March 31.
Wilder will be ringside in the Welsh capital and hopes to take on the victor at some point later this year to prove who the real heavyweight champion is.
“I always said I want to unify all the titles. My goal is to unify,” the 32-year-old, now 40-0 (39), said. “I don’t care about popularity or who has the most money – I want to know who is the best in the world – I want to make the sport about ‘who is the best’. And tonight I did that.
“I am the most dangerous in the world, the baddest man on the planet. I proved that tonight.
“Soon there will be one champion, one face, one name – that will be Deontay Wilder.
“It’s not about how big your muscles are – it’s about the heart.”
“My grandmother told me a long time ago that I was anointed by God.
“I want to unify the division, I want to see who the best in the world is. I know I am. I am going to be speaking loud and speaking proud.
“I am looking forward to Cardiff, I have never been there. I have a lot of friends in the UK. I am going to enjoy myself and look forward to fighting the winner – if they are up for the test.”
