She's only 115 pounds, but Joanna Jedrzejczyk is turning into one of the scariest fighters in the world.
At UFC Fight Night 69 on Saturday, she picked up her first title defense by battering Jessica Penne over three rounds. While the ultimate stoppage wasn't one for the highlight reels, Jedrzejczyk put a beating on Penne and left the challenger bloodied.
Competing in the newest UFC division, Jedrzejczyk has plenty of potential challengers who are waiting for the next shot. However, the Polish competitor is quickly showing why she's the one with the belt in the 115-pound class.
