Ryan Garcia floors Javier Fortuna three times in dominant knockout win

Following a disappointing performance in April, Ryan Garcia impressed against a far better opponent on Saturday 

with a sixth-round knockout of Javier Fortuna in a 140-pound bout in Los Angeles.

The 23-year-old star floored Fortuna in Rounds 4, 5 and 6, all the result of Garcia's lightning-quick left hook.

The first knockdown was produced by a body shot -- and set up by a feint -- but the following two hooks crashed into Fortuna's chin.

After the last knockdown, Fortuna received the referee's 10 count on one knee, the end of the fight coming 27 seconds into Round 6.

"I know that I was sharp. ... I know how good of a fighter I am, I just had to put it all together," Garcia said. 

"The fight speaks for itself. ... When I face harder punchers, I box better. ... I hit hard; it doesn't take a lot to hurt somebody."

Garcia is ESPN's No. 6 boxer at 135 pounds, but his last two fights were contested at 140, a weight he said he's far more comfortable at.

"I'm not going back down to 135 for nothing but I will fight 'Tank' next," Garcia said, referring to a super fight with Gervonta Davis. "If 'Tank' wants it at 140 ... let's get it."

Davis, also a star fighter, campaigns at 135 pounds, but did fight at junior welterweight once, at a June 2011 11th-round TKO of Mario Barrios.
