There were plenty of people placing doubt on Alexa Grasso in her UFC Seattle co-main event against Maycee Barber; however, Grasso put those doubts, and her opponent, to bed.

The two traded for the first couple of minutes, attempting to find each others range while exchanging kicks. The two appeared to be even, as Barber tried to press the pace, but Grasso was more than ready to battle back.

Then, Grasso flashed a right hand, only to crack Barber with a left. Barber was out from the second the punch landed, even as Grasso took the back and looked for a choke.
