There are plenty of reasons to believe Gillian Robertson can pull off the upset at UFC 330. When Robertson walks into Philadelphia’s Xfinity Mobile Arena on August 15, she will be challenging Dern for the UFC women’s strawweight championship. She has eight UFC submission victories, while Robertson currently has nine total submission wins and holds the women’s UFC record. It would give Robertson a victory that people would immediately remember when discussing the greatest submission artists in UFC women’s history. And if “The Savage” can make Mackenzie Dern tap at UFC 330, she won’t simply leave Philadelphia as the UFC strawweight champion.
