TERENCE CRAWFORD won the biggest victory of his career by stopping Shawn Porter in Las Vegas' 10th round.
Crawford retained his WBO Welterweight Championship when he twice floored Porter during round 10, before Kenny Porter, his father, withdrew his son.
Showtime was exhausted after sustaining a cut above the eye from an accidently clash of heads on round three.
Crawford knocked Crawford to the ground with a left jab, indicating his fatigue as an American boxer.
Bud tried to get Porter to respond, but Porter couldn't. One of Bud's combinations was enough to get him back on the ground.
He was furious and began punching the canvas. His dad was not happy.
Crawford began to scream in joy as Porter was defeated by him via TKO.
The WBO welterweight champion celebrated then with his team and danced alongside his mother, who was watching from the ringside.

He celebrated his ninth consecutive stoppage win and hinted that he now wants to challenge Errol Spence Jr., the IBF and WBC champions.
Spence Jr. watched the action from Las Vegas ringside, but he left his seat when Porter died.
Crawford stated in his post-match interview that he had figured out round one that he would win, because he had the reach.
"He wanted me to push him back, but I did it back for him.
"Shawn Porter can be a tough fighter. But I knew that my dad would end it when I dropped him with an uppercut and again.
"I will fight who wants it next, everybody knows who I want [Spence Jr.]
"I told Shawn Porter I love him and that Shawn Porter is a good friend of mine. I never wanted him to fight me."
