Former two-time women’s strawweight titleholder “Thug”  Rose Namajunas picked up her second win as a flyweight on Saturday, defeating  Tracy Cortez via unanimous decision in the UFC Denver main event.   Namajunas used a stiff jab, footwork and timely takedowns to end Cortez’ 11-fight winning streak.  She was able to land and get out of the way of return fire without absorbing much damage.
