Ryan Garciadidn’t need much time to score the win…

In an eye-opening performance, the 21-year-old Mexican boxer stopped Francisco Fonseca in the first round of their lightweight bout with a blazing counter left hook that left his opponent flat on the canvas on Friday.

Referee Raul Caiz Sr. counted out Fonseca at 1 minute, 20 seconds.

It was a dazzling display of reflexes, timing and power, as Garcia (20-0, 17 KOs) caught Fonseca (25-3-2, 19 KOs) with a flush shot he never saw coming.

“It was good,” Garcia said of the knockout punch. “[The fight] didn’t last that long, but I watched a video of Sugar Ray Robinson, and he did this little feint and threw the perfect left hook. I saw it and went for the left hook. Thought I was going to go longer, not going to lie. I respect Fonseca and thank him for the opportunity.”

For Garcia, who was ESPN‘s 2017 prospect of the year, it was another step in his development as a fighter and a box-office attraction. Friday night’s card played to an announced crowd of 10,310.

Garcia has shown steady improvement under the direction of trainer Eddy Reynoso, best known for developing light heavyweight titleholder Canelo Alvare zinto one of the best boxers in the world.

The victory could set up a possible fight with former three-division world titlist Jorge Linaresin a classic crossroads matchup pitting a young rising star versus a seasoned, proud former champion.

“I’m 21, I’m a late bloomer,” Garcia said. “I’m ready for everyone, and I’m comfortable. I’m ready to go after everyone. I’m turned up. Let’s go.”
