Called the most decorated amateur boxer in U.S. history, with 145 wins, 11 national titles and six USA gold medals, Ramirez delivered a brutal body shot that rocked Seigwarth before unloading a barrage of shorts to the head.
BoxingInsider.com tweeted a picture of the ref stopping the fight at the MGM Grand Garden arena in Las Vegas. There has not been any announcement on when Ramirez will fight again.
