Despite Maycee Barber 's impressive winning streak , with six wins, she is still considered the underdog in this matchup. Erin Blanchfield's high level of grappling and the fact that she has already fought five-round bouts in the UFC should be advantages against Maycee Barber , making the 'Cool Blooded' the favorite at stake.bet.br in a fight that is likely to be longer.

Dustin Jacoby 's knockout power invites MMA fans to bet on the American. The athlete recovered from a losing streak by defeating a Brazilian, Vitor Petrino , at UFC Tampa . Newly arrived in the UFC, Bruno Lopes will need to be very technical and quite defensive to avoid being vulnerable to a 'one-handed' strike that could end the fight.
