Katie won the bout in Baku.
Taylor went face-to-face with her old rival, who is also the last boxer to have defeated the Irish star back in 2011, and laid a firm marker for exciting times to come.
Taking the opening two rounds on 30-27, Katie continued to hold her own in the final two rounds to secure a unanimous 3-0 decision from the judges.
Katie was crowned winner.
Well done Katie Taylor, she is through to the quarter finals on 24th 12:45
