Alexa Grasso upsets the odds and defeats Valentina Shevchenko to clinch UFC gold

Alexa Grasso is a world champion.

One of the most dominant reigns in women's flyweight history has come to an end with Valetina Shevchenko losing her belt to sixth-ranked Grasso.

She becomes the third Mexican-born champion in UFC history following Brandon Moreno and Yair Rodriguez.

Prior to the fight, the bookies in Las Vegas had her at 25/1 to beat Shevchenko.

From the very first bell in the co-main event at UFC 285, Grasso dominated the fight.

On the feet, she proved too much for Shevchenko, landing a number of shots which appeared to rock the champ.

And on the ground, she was simply unstoppable – eventually winning the bout thanks to a rear-naked choke in the fourth round.

For the finish, she expertly capitalised on Shevchenko's mistake, dodging a spinning back kick before sinking in the deep submission.

Incredibly, the commentary booth revealed that she'd actually trained for that exact situation during her camp.

Championship mentality.

Overcome with emotion after the fight, Grasso dedicated her victory to her team as well as her partner.
