A 23-year-old scored a thumping 30-second knockout Saturday, and said after he wasn't even surprised

• Miguel Gaona scored a lightning-fast finish in his second pro boxing bout Saturday in Los Angeles.
• The youngster beat his opponent Gilberto Aguilar like he owed him money.

LOS ANGELES — 23-year-old boxer Miguel Gaona scored a 30-second knockout Saturday, and said after his win that he wasn't even surprised that he wasn't surprised at the thumping finish.

It all went down during the preliminary section of the Golden Boy Promotions event held at the Galen Center in Los Angeles, broadcast on DAZN.

Gaona is a boxing novice who had only one pro fight to his name before he swung fists at super lightweight opponent Gilberto Aguilar for a four-round bout.

But the burgeoning prospect showed few signs of inexperience as he essentially bullied and bludgeoned his way to a grueling victory after a somewhat patient and methodical start.

Gaona stepped forward and measured the distance to Aguilar with pawing shots before unloading with a merciless attack when he had backed his opponent into the corner.

Gaona mixed his attack up with head shots and body blows and it seemed like the latter left Aguilar in a heap on the floor, unable — or unwilling — to continue.

Watch the knockout right here:

In a statement sent to Insider, Gaona, who advanced his pro boxing record to two wins (one knockout) with the finish, said: "I am not surprised by the early knockout.

Later, Insider saw Gaona fraternizing with friends and fans near press row, and he barely had a scratch on him.

"This is what we trained for," he said. "[I'm] just happy we were able to get it done early."
