On October 2, 1980, at Caesars Palace in Las Vegas, Holmes defended his title against Muhammad Ali, who was coming out of retirement in an attempt to become the first four-time World Heavyweight Champion. Holmes dominated Ali from start to finish, winning every round on every scorecard. At the end of the tenth round, Ali's trainer, Angelo Dundee, stopped the fight. It was Ali's only loss without "going the distance" for a judges' decision. After the win, Holmes received recognition as World Heavyweight Champion by "The Ring".
