Los Angeles: David Benavidez outclassed Ronald Gavril to easily retain his WBC super-middleweight crown with a unanimous points victory on Saturday.
The 21-year-old champion from Phoenix dominated Romania's Gavril to claim a deserved win at the Mandalay Bay Events Center in Las Vegas.
Benavidez had beaten Gavril, 31, last September by a split decision to claim the vacant crown in one of the best fights of 2017.
An ill-tempered build-up to the rematch had seen Gavril vowing to right a wrong, claiming he had robbed of victory in the first fight.
But on Saturday there was only one winner, with Benavidez using his stinging jab and superior movement to toy with Gavril on his way to a resounding victory.
One judge scored it 119-109 while the two other cards had it 120-108 in favour of Benavidez, who improved to 20-0 with 17 knockouts after the win.
Benavidez, the youngest active champion in world boxing, said he had sought to exploit Gavril's aggressive tactics.
"I knew he was going to come in aggressive -- like I said before he's a one-trick pony, he don't know anything else but pressure," Benavidez said. "So I used that to my advantage -- jabbed, boxed him all day and when I saw an opening I took it. I didn't knock him out but he's a tough son of a gun."
Benavidez said he was unfazed by the bad blood that had simmered between the two fighters before the bout.
"I don't really care," he said. "I had the better of him. Look at his face and look at mine," he added.
