Terence Crawford has followed his defeat of Australia's Jeff Horn with a stoppage victory over Jose Benavidez in hometown Omaha, Nebraska.
Crawford, a three-division champion who was making his first defence of the WBO welterweight belt he reclaimed by beating Horn in June, stuck out his tongue at his fallen opponent after what amounted to a personal grudge match.
"It feels so good to shut somebody up who has been talking for so long," Crawford said. "I'm at ease."
He used an uppercut to fellow American Benavidez's chin to knock him down the first time in the 12th and final round and then consecutive rights to put him down a second, prompting the referee to stop the fight with 18 seconds left.
Next up for Crawford could be a unification bout with IBF champion Errol Spence Jr., something promoter Bob Arum has said he would like to make happen sometime in 2019.

"Hear me now: I'm ready to make that fight next," Arum said. "We're prepared to sit down and get that fight done, but I can't force the other people into doing it."
The 31-year-old Crawford (34-0, 25 knockouts), ranked first or second on the world's top pound-for-pound fighter lists, put on a workmanlike performance for the first half of the fight in front of a hometown crowd of 13,000 in Omaha Nebraska that included Crawford friend and billionaire Warren Buffett.
Benavidez (27-1, 18 KOs) began tiring in the seventh after taking body shot after body shot.
"I take nothing from him," Benavidez said. "He's the best of the best. I feel like I did a good job."
