Mackenzie Dern defeated Amanda Cooper via Submission in R1
Despite being over the scales for this fight, it just took Dern 1 round to dispatch off the over confident Cooper with her striking. Cooper ate a right hand in the opening seconds of th first round but was unfazed and kept on moving forward. Her striking and head movement was clearly way below Dern’s who landed another looping strike. Dern notices her right hand landing and unleashes a powerful over hand right that drops Cooper to the ground. In no time, the rear naked choke sinks in and Cooper taps out.
