An American stole the show Saturday at Bellator 266 with merciless ground-and-pound, then clapped back at internet trolls who dared to ever doubt him.

Ben Parrish, in his first fight since breaking a leg in the cage, stormed to a quick-fire 38-second knockout win over Christian Edwards at the SAP Center in San Jose, California.

It was the shock result of the night as Parrish was a considerable underdog in the bout, however, the fighter nicknamed "Big Tuna" took Edwards into deep waters and drowned him with brutal strikes.

"It feels good to shut a lot of people up," Parrish said after his win. "Man, that's all I will say."

In the video below, you can see Parrish land a hammer of a left hook on his opponent's jaw.

The connection produced such a thudding noise that it was clear Edwards was going to drop to the floor.

From there, Parrish threw a further five blows to his opponent's head.

Watch the finish right here:

"I told my boss, Casey, back home, I'll knock him out with a left hook," Parrish said in a statement sent to Insider.

"What'd I say? Don't get it twisted, everybody will find an excuse to throw salt on me - hey, that's not luck, that's preparation, baby.

"If I can't do it with six months of training, beat him, nobody was gonna beat him."

Neiman Gracie says it's the hospital or cemetery for his opponents

Elsewhere on the Bellator card, 32-year-old Brazilian fighter Neiman Gracie showed off his developing skillset as the second degree Brazilian jiu jitsu black belt scored a first-round finish with elbows and punches.

The victory was Gracie's first by knockout. He has otherwise finished his other opponents by submission.

After the match he sent a warning message to his rivals.

"I don't need to take people down to win fights anymore," said Gracie. "I can do it all, but if I take you down, oh boy.

"I saw he was putting his head down so I come up with the uppercut. If you keep the fight standing, it's the hospital. If you go to the ground, it's the cemetery."

Elsewhere, in the main event, Phil Davis beat Yoel Romero in a unanimous decision.

He credited the win to his parents.

"I just want to say to my mom and dad - by God's grace, they're still here, my mother's in the crowd, my father's at home staring at the TV crying.

"I love you guys and I cannot do this without you. You guys are amazing."
