She was not yet old enough to drink when she introduced herself to the MMA masses with a sensational 12-second flying armbar submission on Kathina Catron at Invicta Fighting Championships 5 in 2013. Now one of the top women’s strawweights in the world, Rose Namajunas turns 25 on June 29.

Just nine bouts into her professional career, “Thug Rose” has only begun to scratch the surface of her immense talent. A finalist on Season 20 of “The Ultimate Fighter” reality series, Namajunas has compiled a 4-2 record under the Ultimate Fighting Championship banner while emerging as the No. 1 contender for Joanna Jedrzejczyk’s women’s strawweight title. The Grudge Training Center rep last appeared at UFC on Fox 24 in April, when she submitted Michelle Waterson with a second-round rear-naked choke at the Sprint Center in Kansas City, Missouri. Namajunas owns other notable victories over Tecia Torres, Paige VanZant and Angela Hill. She holds the rank of black belt in karate and taekwondo but has secured five of her six wins by submission. Barring injury, Namajunas figures to challenge Jedrzejczyk for the 115-pound crown later this year.
