Former UFC strawweight champion, Jessica Andrade has retained her rank at #1 in the official flyweight rankings tonight — opening the main card of UFC 266 with a dominant, one-sided knockout victory over Cynthia Calvillo — becoming the first fighter to stop Calvillo.

Andrade, a former undisputed strawweight champion under the promotion’s banner, rebounded from an April knockout loss to current flyweight champion, Valentina Shevchenko, with her usual, bullish, and aggressive style, constantly pressing Calvillo at the fence.
