Demetrious Johnson added a second submission win to his credit since becoming UFC flyweight champion, ending the challenge of Chris Cariaso Saturday night at UFC 178.

With the win, Johnson earned his fifth successful title defense and his seventh straight win – a mark that is third-best in the UFC currently.

“I feel good,” he said. “It was a great fight. Chris was a tough opponent. I was just a little too patient for my own good.”

Asked what he meant by “too patient,” Johnson stated he didn’t completely open up until his coaches told him to.

“Mighty Mouse” is now 21-2-1 overall, having not lost since a 2011 fight vs. Dominick Cruz for the UFC bantamweight title. He is unbeaten in his last eight overall, having fought Ian McCall to a draw in 2012.

After turning back the challenge of Cariaso, and having already bested the likes of John Dodson, John Moraga and Joseph Benavidez, Johnson was asked who might be next?

“I am not a man who calls out opponents,” he said. “I am a man who sits by the phone, answers it and goes out and fights.”

Despite the near-flawless performance, Johnson said there is “still a lot of work to do. It was a good night.”
