Boxing analyst and former world champion, Paulie Malignaggi was part of the commentary team for the fight and he detailed his amazement at the skill shown by Charlo.
"It's amazing. He blocks a punch with the same hand that he throws the uppercut," Malignaggi explained. " I thought he took the right hand first, but he didn't take the punch at all.
"He actually blocks the punch, with the same hand as he's rolling, holds his ground and then fires back with that. Amazing."
Charlo's win was his 19th stoppage in just 25 fights, keeping him unbeaten as a professional, as Williams endured his first career defeat.
Charlo is using the weekend's coming out party as his springboard into the elite level of the sport and he wasted little time in eyeing up some of the biggest names in Boxing.
"I want to unify the WBO with Canelo, the WBC and the WBA. Where are you Canelo? Charlo said. "I want to prove I'm the best junior middleweight in the world".
"None of them are on my level. I've worked very hard throughout my career. I haven't been given anything".
Amazingly Jermall has an identical twin brother, named Jermell, who not only fights in the same weight division, but holds the WBC world title.
Jermall is the older brother, beating his twin by a minute, however his younger brother has the edge in the boxing ring, with a 28-0 record, compared to the IBF champion's 25-0.
