Lightweight Damien Brown got UFC 201 off to a tremendous start on Saturday night when he finished opponent Cesar Arzamendia with a series of punches in their UFC Fight Pass prelims bout.

Brown and Arzamendia started exchanged blows early and often, with each fighter scoring points on the feet in the opening 30 seconds. Less than a minute in, however, Brown caught Arzamendia with an overhand right that sent "Goku" crumbling to the canvas.

Arzamendia was able to recover -- and even threatened with a heel hook -- but Brown escaped and made his way back to his feet. Once the fight was standing again, Brown went back into attack mode, landing a counter right hand that put his opponent out on his feet before following up with yet another right hand.

Referee Marc Goddard stepped in and called and end to the fight at the 2:27 mark of the first round.

"I had him rocked early and I could tell right away it was going to take work to put him away, he was far from out the first time and he's a really tough guy," Brown said after the fight. "The heel hook he got on me was tight, it was really tight, he had the hook but he didn't have his bottom leg in position so I knew I could get out of it.

"I took two months off from my job to train for this fight and I will continue to do that for at least the next couple of fights so that I can continue to put on performances like that," Brown continued. "I don't call people out, but I don't want to leave this sport without fighting the best so I hope whoever is next is someone good."

With the win, Brown improves to 16-9 overall and 1-1 inside the Octagon.
