UFC Seattle Results: Alexa Grasso KO’s Maycee Barber (Video)

We have you covered for all of tonight’s UFC Seattle results, including the co-main event rematch between Maycee Barber and Alexa Grasso.

Barber (15-3 MMA) will enter the contest on a seven-fight winning streak, with her most recent victory coming over Karine Silva by way of unanimous decision this past December at UFC 323. ‘The Future’ has not tasted defeat since her first encounter with Grasso back in February of 2021, a fight which she lost by decision.

Meanwhile, Alexa Grasso (17-5-1 MMA) will be looking to snap a two-fight losing skid when she rematches Maycee Barber this evening. The former flyweight champion is coming off back-to-back unanimous decision losses to Natalia Silva and Valentina Shevchenko in her most recent Octagon appearances. The Mexican’s most recent win came back in March of 2023, when she dethroned the aforementioned Shevchenko at UFC 285.
