Veteran combat sports reporter Kevin Iole was in awe of what the young gun was dishing up.
"Stevenson is just amazingly fast and he's landing so many hard shots," Iole tweeted.
"Just amazing difference in hand speed between these two guys. Stevenson is a blur. And those punches are H-A-R-D.
"This guy is the real deal. I know his opposition isn't elite, but this is remarkable and impressive stuff."
After three rounds of the one-sided contest, Stevenson had landed 66 punches to Caraballo's seven. And the beatdown only got worse from there as the mismatch between the fighters was made painfully clear.
"I came here to get him out of there," Stevenson said. "My mindset was focused on getting him out of there.
"I hit him with everything I could early, I wobbled him a bunch of times, and I started realising the head shots weren't going to do it, so I went to the body."
Some in the boxing world have already compared Stevenson to Floyd Mayweather, but he wasn't buying into that talk.
"We're two different fighters, we've got different styles," he said. "I've stolen stuff from his game, but I've also stolen stuff from Pernell Whitaker, Terence Crawford, Andre Ward.
"I've stolen stuff from a lot of guys. It's not just Floyd that I try to put in my game. It's a huge compliment, but I'm still my own fighter."
Social media went wild for Stevenson as plenty questioned how Caraballo managed to survive as long as he did.
