Vasyl Lomachenko has retained his WBO super-featherweight title with a seven-round demolition of Nicholas Walters.
The fight came to an abrupt end when the Jamaican told referee Tony Weeks before the start of the eighth round, "I don't want to continue."
Two-time Olympic champion Lomachenko registered the biggest victory of his career in dynamic fashion as it was the second defence of his title and just his eighth professional fight.
"He just stood there in one place which made it easy for me," the Ukrainian said of Walters.
Lomachenko dominated the previously unbeaten Walters from the opening bell, scoring at will by landing hard punches in the final round of the beatdown at the Cosmopolitan in Las Vegas.
Walters' face showed signs of the punishment, but it appeared that he could have continued if he chose to.
It was a painful first defeat for Walters, as his decision to quit in the middle of the fight dropped his record to 26-1-1 with 21 knockouts.
Walters blamed his poor performance on taking a year off between fights.
"It wasn't about quitting," Walters said. "In the last round he caught me with good shots. I was hanging on just to survive. It would be stupid to come out after the last round."
With his victory Lomachenko - who compiled an amateur record of 396-1 with Olympic gold medals in 2008 and 2012 - is now 7-1 as a professional.
