On this day in history, Feb. 25, 1964, a young Muhammad Ali knocks out Sonny Liston to win first world title

President Trump is considering pardoning the late boxing great Muhammad Ali.

Young Muhammad Ali, then known as Cassius Clay, knocked out opponent Sonny Liston for his first world title in boxing on this day in history, Feb. 25, 1964.

Twenty-two-year-old Clay achieved the unthinkable by dethroning Liston, who was then the world heavyweight boxing champion, according to History.com.

Ali beat the steep odds by winning the fight in a seventh-round technical knockout.

The fight brought 8,300 fans to the Convention Hall in Miami Beach, Florida, to watch the matchup between Liston and Clay, whose nickname back then was the "Louisville Lip."

Liston was an eight-to-one favorite after building a reputation for pummeling other champs like Floyd Patterson, History.com reports.

Ahead of the historic match, Clay predicted he’d knock out Liston in the eighth round and would "float like a butterfly, sting like a bee."

But it turned out that Clay needed less time to take down Liston, who complained of a shoulder injury suffered in the first round.

This reportedly caused Liston to throw a few swings unsuccessfully as Clay delivered "quick and punishing jabs" to Liston’s head, History.com noted.
