Terence Crawford rudely welcomed Jeff Horn to the U.S. Saturday night, as “Bud” scored himself a ninth-round stoppage win to become the WBO welterweight champion.

The bout headlined an event from the MGM Grand Garden Arena in Las Vegas that aired live on ESPN+, the new all-digital network.

Crawford (33-0) won his third world title in three different divisions.

“Like I told you all before, I’m strong. I was way stronger than him. You all kept telling me how strong he was, so I had to go and show you,” Crawford said (thanks to ESPN for the quotes). “I just had to get in the ring and prove it. You saw what I did in there. My power carried up, my physicality. Now I want all the champions at welterweight.”

Crawford out-landed Horn 155-58 and threw over 100 more punches in the bout. He previously won titles in both the lightweight and junior welterweight divisions.

“His future is unlimited. He’s a terrific fighter. It’s the highest praise I can give a fighter, a welterweight, that he reminds me of Sugar Ray Leonard,” said Arum, who promoted several Leonard fights. “That to me is a great, great compliment because I always thought Leonard was the best and this guy is equal or better than Ray.”

Horn suffered his first career loss, falling to 18-1-1. The Australian won the WBO title last year with a decision victory over Manny Pacquiao, and defneded it in December vs. Gary Corcoran.
