Errol Spence Jr dominated Mickey Garcia to easily win on points and see him defend his IBF welterweight title for the third time in Dallas.
Although Spence was taken the distance by four-weight world champion Garcia the outcome never looked in doubt and all three judges awarded Spence every round.
It was Spence’s first 12-round bout in his past 12 fights, but judges scored the fight 120-107 120-108 120-108 in the 29-year-old’s favour.
The previously undefeated Garcia, who moved up from 135 to 147 pounds in preparation for the bout, lost his first fight in his previous 40 professional encounters.
The victorious Spence said: "Throughout training camp, a lot of commentators thought he was too smart and I couldn’t box as well as him. I showed I can box and I can move my head if I want to.
"The game is to be smart. It’s the sweet science. I had the size and reach advantage, so why not use it to take away the jab? It’s a weapon for me and it takes away one of his weapons."
A disappointed Garcia said: "My brother (trainer Robert Garcia) wanted to maybe stop the fight in the later rounds. He didn’t want to let me get hit more, but I told him I was fine and I tried to go out there and pull it off.
"I thought I could have landed one good shot to change everything, but I wasn’t able to land it."
Spence was able to land 345 of the 1,082 punches he threw in the fight- an impressive 32 per cent.
He grew up in Dallas, and added: "The motivation fighting in front of my hometown crowd made me feel great. These people have supported me since day one and I wanted to put on a good performance for all of them."
