Muhammad Ali vs. Sonny Liston
Sonny Liston was a 7-1 favorite to retain his title against the 22-year-old Cassius Clay. Few people thought that Clay would be able to withstand Liston's power and unyielding pressure. One of the few exceptions was Clay himself, who predicted he would dethrone Liston.
It was clear early on that the challenger's speed and jab was giving Liston problems. After the fourth round, Clay returned to his corner, complaining that he could not see. He instructed trainer Angelo Dundee to cut off his gloves, that he could no longer fight. Dundee washed out his fighter's eyes and convinced him to continue. It has long been speculated by Dundee that ointment got onto Liston's gloves — perhaps intentionally — and into Clay's eyes.
When the fight resumed, Clay continued outboxing the champion. Liston's right eye was badly swollen, and after the sixth round Liston refused to continue, relinquishing his title on the stool. After this fight, Clay changed his name to Muhammad Ali.
