Free fight – Alexa Grasso against Valentina Shevchenko II

Alexa Grasso and Valentina Shevchenko probably couldn't have chosen a more spectacular venue for the third fight in their series.

This weekend's UFC 306 (or Riyadh Season Noche UFC for branding reasons) will see the two most outstanding flyweights in the world square off for the third time – this time inside the Las Vegas Sphere – after Mexico's Grasso won their previous two bouts by submission and their last fight ended in a draw almost exactly a year ago.

The trilogy match will be one of the main bouts in the highly anticipated Sphere tournament, which is reported to have operating costs of over $16 million, ahead of what Dana White says will be the most spectacular event in the organization's thirty-year history.

And if their third fight goes anywhere near as well as the last two, it will live up to expectations. Below is the razor-thin draw between Grasso and Shevchenko a year ago.
