By the Numbers: UFC Vegas 101

Mackenzie Dern put on a jiu-jitsu clinic to exact her revenge against Amanda Ribas.

After a competitive first 10 minutes, Dern went to work in methodical-yet-effective fashion to secure an armbar submission at the 4:56 mark of Round 3 in the UFC Vegas 101 headliner at the UFC Apex in Las Vegas on Saturday night.
