Mackenzie Dern didn’t get the submission she was hoping for in her mixed martial arts debut, but the strawweight prospect dominated Kenia Rosas for 15 minutes at Legacy FC 58. Rosas, a fellow MMA newcomer, was able to survive many submission attempts by the current No. 1 pound-for-pound grappler in the world, but Dern wasn’t upset about it.
"I’m always confident in my jiu-jitsu, especially since it was Kenia Rosas’ pro debut, and it was my first fight, so I was definitely confident in my jiu-jitsu," Dern told Ariel Helwani on a recent edition of The MMA Hour.
