Andrea Lee is not celebrating her performance at UFC on ESPN+ 12 despite it resulting in her third consecutive octagon win.

Lee (11-2 MMA, 3-0 UFC) kept perfect in the octagon on Saturday when she defeated Montana De La Rosa (10-5 MMA, 3-1 UFC) by unanimous decision at UFC on ESPN+ 12. “KGB” is tied with champ Valentina Shevchenko for the longest active winning streak in the women’s flyweight division, but Lee is not immediately focusing on the positive.

Despite getting 30-27, 30-27 and 29-28 scorecards in the win, Lee was highly critical of what she showcased in the cage.

“I thought this was probably the worst fight I’ve ever had,” Lee said in her post-fight quote distributed by UFC. “I was not very happy about my performance, but I got to go back and watch everything. She is a great wrestler, luckily she was not able to do much after the takedowns and I could get back on my feet every time, I just feel I didn’t throw enough volume. I don’t know what it was.”

UFC on ESPN+ 12 took place at Bon Secours Wellness Arena. Lee vs. De La Rosa streamed on ESPN+ following prelims on ESPN.

Lee, 30, was not immediately able to identify the source of what she considered a lackluster performance. She admits it wasn’t exactly a smooth road leading up to fight night, but had no complaints to speak of in terms of her physical and mental state heading into the octagon.

Nevertheless, Lee was able to get the job done to remain unbeaten over more than three years. The win over De La Rosa will take her further up the 125-pound rankings, but before thinking of her next move, Lee wants to continue to analyze what happened at UFC on ESPN+ 12.

“I felt great going into the fight, but you are not always the same in your fights,” Lee said. “There are always things going on in your life, maybe that’s what affected me. I’m not blaming anyone or anything. I just think I could have done better and I should have done better. I had an amazing camp, I was just not able to let it go. But I just proved to myself and everybody else that I’m not going to quit.”
