About Muhammad Ali Wins Heavyweight Title: February 25, 1964

Cassius Clay walked into Miami Beach Convention Hall on February 25, 1964, as a 7 to 1 underdog. Nobody believed the 22 year old loudmouth could beat Sonny Liston. Bookmakers barely offered odds on Clay winning. By the time the night ended, the sports world had seen something it would never forget.

The Heaviest Favorite in Boxing History

Sonny Liston had destroyed Floyd Patterson twice, both fights ending in the first round. Sports Illustrated predicted Clay would lose badly. The boxing establishment treated Liston as unbeatable and Clay as an entertaining distraction who talked too much.

The Weigh In That Convinced Everyone Clay Had Lost His Mind

Clay arrived at the official weigh in screaming that he would eat Liston alive. His pulse measured 120 beats per minute, double the normal rate. The Miami Boxing Commission considered cancelling the fight. His corner later confirmed the entire scene was deliberate psychological warfare designed to rattle Liston before the first bell.

Eyes Burning, Still Fighting

By round four, a substance from Liston's gloves caused burning in Clay's eyes. Clay told his trainer Angelo Dundee to cut off his gloves. Dundee refused and shoved him back out. Clay survived the round running backward and came back sharper. His movement frustrated Liston through rounds five and six.

Liston Stayed Seated

Between rounds six and seven, Liston sat on his stool and did not stand up. He told his corner his shoulder gave out. The referee counted him out. Liston, the man who had made every challenger look ordinary, quit on his stool. Clay ran to the ropes screaming that he had shocked the world.

The Name Change Nobody Saw Coming

The next morning, Clay held a press conference with Malcolm X at his side. He announced he had joined the Nation of Islam and rejected the name Cassius Clay. Elijah Muhammad gave him the name Muhammad Ali within days. Broadcasters and sportswriters who refused to use the new name found themselves increasingly out of step with history as his legacy grew.

Why February 25 Still Trends Every Year

Ali's win on this night opened the door for athletes to be more than performers. He declared that a fighter could choose his own identity and speak about the world he lived in. Every athlete who has taken a public stance on anything traces some thread back to what happened in Miami on February 25, 1964.
