The battered face of a winner

Moving remorselessly forward, Joe Frazier, that gritty stump of a man, won a unanimous decision at Madison Square Garden on Monday night to become the undisputed heavyweight champion of the world. Frazier not only beat Muhammad Ali to the punch, he licked him in the prophecy department. "Clay is good," he said beforehand, "but he isn't good enough to escape." He wasn't. Ali, in turn, billed the bout as The Return of the Dancing Master. It wasn't. Ali didn't get up on his toes and jab; he chose, disastrously, to hook with a hooker. By this, Ali gave away his 6½" advantage in reach.

Ali gave away much more by his bizarre charades—lying against the ropes, the pretty red tassels on his shoes drooping lifelessly; shouting sepulchrally to the press, "Nooo connntesssst"; beckoning Frazier to hit him; shaking his head defiantly when hit; tapping Frazier on the forehead as though testing for termites. But these acts, designed to steal time, failed in their purpose. Ali's time was past.

It was Frazier's hour, as became manifest in the 11th round, when a big hook left Ali rubber-legged. In the 12th Frazier folded Ali like a carpenter's rule with successive shots to the belly and head, and in the final round a sweeping left hook, which seemed to start at Frazier's shoe tops, put him down for a four-count, closing a reign of both majesty and mystery.

'EVERYONE WILL REMEMBER WHAT HAPPENED'

He has always wanted the world as his audience, wanted the kind of attention that few men in history ever receive. So on Monday night it was his, all of it, the intense hate and love of his own nation, the singular concentration and concern of multitudes in every corner of the earth, all of it suddenly blowing across a squared patch of light like a relentless wind. It was his moment, one of the great stages of our time, and it is a matter of supreme irony that after all the years that went info constructing this truly special night Muhammad Ali was in fact carefully securing the details for his own funereal end—in front of the millions he moved deeply.

The people, he said, would be in the streets of Africa and Asia waiting for word of what happened, and what they have heard—by now—is what they never will really believe. The sudden evil of Joe Frazier's left hook, Ali's bold effort to steal time by theatrics, his wicked early pace that left him later without any guns and his insistence on hooking with a hooker (a bad bit of business)—all of this combined to provide the push for his long, long fall from invincibility. It left Frazier at last the only heavyweight champion of the world and the survivor of one of the most destructive fights among big men in decades.

The first dramatic damage to Ali came in the 11th round when Frazier hooked him to the head and followed with a cruel left to the body that sent Ali rolling back to a neutral corner, a man who seemed caught in an immense, violent wave. He hung on, but his eyes took on a terrible softness and they were never the same again. At the bell, water was thrown in his face before he could reach his corner. There, with his medicine man, Bundini, desperately trying to inflame him, and his trainer, Angelo Dundee, shaking a finger frantically in his face, he was pasted back to a semblance of one piece. As he came out for the 12th, one could see that something was wrong with the right side of his face; it was swelling rapidly and his jaw seemed broken.

He spent almost the entire 13th round in a neutral corner, but he was not active and appeared in a trance, oblivious to the hoarse scream of Bundini: "You got God in your corner, Champ!" Ali responded in the 14th, but not convincingly, even though he did win the round; by now both fighters, their bodies graphically spent, were continually draped over each other, looking like big fish who had wallowed onto a beach. Then, in the 15th, Frazier exploded the last shells from that big left gun. It was near the middle of the round, and the left boomed into Ali's face (see cover), sending him to the canvas with his head ricocheting frightfully off the floor, his feet waving in the air. He got up and finished the round, but he had lost.

The work of Frazier—his glinting animalism, his intensity of purpose—cannot be minimized or in any way discredited. This was not a negative victory; his smothering pressure contributed much to Ali's weird behavior, the options Ali took in strategy and the exhaustion that began to devour him about the sixth round.

The bout was exciting, theatrical and bizarre—and a mild disappointment to some. "Neither fighter did well what he does best," said Cus D'Amato, boxing's mad scientist. "Frazier, the body puncher, went more effectively to the head, and Clay, the dancer, was flat-footed. But either because of this, or despite it, it was drama of the highest order."

It was obvious what Ali had in mind from the opening bell and, perhaps knowing what he had left in him, he followed the only course open: attack this machine early, shake his confidence. It was a sound tactic; early is when Frazier is most accessible. From the start Ali used flamboyance in an attempt to deflate Frazier's spirit. When both arrived in the ring, he danced across it with a smile on his face, brushing abrasively close to Frazier, almost up against him, but the ploy appeared fruitless. In the first moments Ali began doing what he would repeat throughout the early rounds of the fight: every time Frazier's left hook caught him he would shake his head vigorously, telling his audience that the punch did not bother him, telling Frazier that he was wasting his time.

Ali was effective for a while, and there was a clean line to his work. The jab probed and distributed pain and perplexed Frazier. Joe seemed to be trying to stay low, but more and more he began to raise himself into the range of Ali's firepower. Soon, however, it was clear that he was not doing this out of confusion but by design. He was going to take what Ali had to give, and in so doing—he undoubtedly thought—he could intimidate Ali. Frazier took it all—the hard jabs by Ali and that flashing right that traveled instantly behind it. In the third round Joe came out smiling, as he often does at this point in his fights, and he beckoned for Ali to come out to meet him.

A long night was still ahead for Frazier, because this was an Ali determined to put a muzzle on all the mouths that have questioned his courage, his will, his ability to handle pain. "That man," Frazier said later, his own face covered with pyramids of hurt, "can sure take some punches. I went to the country, back home, for some of the shots I hit him with." And Ali's jab faded like a sick flower. His once remarkable legs gone, his arms heavy, he hung on the ropes and spent long and dangerous periods in the corners; it was astonishing that he escaped serious damage. "The way they were hitting," said Referee Arthur Mercante, "I was surprised that it went 15. They threw some of the best punches I've ever seen."

"Everyone will remember what happened here," Ali had said before the fight. "What I want them to remember is my art and my science."

They will remember. Though not as he intended.

SI's 100 Greatest Photos of Muhammad Ali

Neil Leifer

In one of the most iconic and controversial moments of his career, Ali stands over Sonny Liston and yells at him after knocking the former champ down in the first round of their 1965 rematch. Skeptics dubbed it "the Phantom Punch," but films show Ali's flashing right caught Liston flush, knocking him to the canvas. Refusing to go to a neutral corner, Ali stood over Liston and told him to "get up and fight, sucker."

Neil Leifer

At 22-years-old, Cassius Clay (Muhammad Ali) battered the heavily favored Sonny Liston in a bout that shook the boxing world. The fight ignited the career of one of sports' most charismatic and controversial figures, whose bouts often became social and political events rather than simply sports contests. At the peak of his fame, Muhammad Ali was the best known athlete in the world. Liston, one of the most feared heavyweight champions in history, was a 1-8 favorite over the young challenger known as the Louisville Lip. But Clay, here stinging the champ with a right, used his dazzling speed and constant movement to dominate the action and pile up points.

Marvin E. Newman

For the 18-year-old from Louisville, here atop the medal stand after his Olympic victory, all roads led from Rome. Clay finished his amateur career with a record of 100-5 and made his professional debut two months after the Games.

Neil Leifer

Undefeated in his first 17 pro fights, Clay mugged for the camera before the start of his 1963 bout against Doug Jones in Madison Square Garden.

Neil Leifer

Trainer Angelo Dundee urged his young charge to get serious before the opening bell against Jones. Clay followed instructions and emerged from a tough fight with a unanimous decision victory. Three months later he would stop Henry Cooper and close out 1963 at 19-0.

Neil Leifer

A seemingly hysterical Clay taunted Sonny Liston during the pre-fight physical for their 1964 bout. He had consistently baited the Big Bear during the lead-up to the fight, saying he was going to "use him as a bearskin rug ... after I whup him." The Miami Boxing Commission would fine Clay $2,500 for his outburst at the physical.

Neil Leifer

"I shook up the world!" an emotional Clay hollered to ringside reporters after his shocking defeat of Liston. And he did just that, claiming the heavyweight title at age 21 after a clearly beaten Liston, complaining of a shoulder injury, failed to answer the bell for the seventh round.

Neil Leifer

Draped in shadow, the young king — now known as Muhammad Ali — stared down the camera during a photo shoot in April 1965, one month before his rematch against Sonny Liston.

Neil Leifer

As Liston lingered on the canvas and the referee, former heavyweight champ Jersey Joe Walcott, tried to control Ali, the 2,434 spectators on hand in the Lewiston, Me., hockey arena — a record low for a heavyweight championship fight — tried to make sense of what all that had happened in less than two minutes after the opening bell.

Neil Leifer

The celebration over Liston continued. In a chaotic ending, Ali was awarded a knockout when Nat Fleischer, publisher of The Ring, informed referee Jersey Joe Walcott from ringside that Liston had been on the canvas for longer than 10 seconds after Ali knocked him down. The bout remains one of the most controversial in boxing history, with many observers insisting that Liston took a dive.

Neil Leifer

Ali's second title defense came in November 1965, against former two-time heavyweight champion Floyd Patterson. During the build-up to the bout, the normally soft-spoken Patterson earned the new champ's wrath by refusing to call Ali by his Muslim name. At the weigh-in, Ali's glare made it clear that he intended Patterson to pay for the disrespect.

Neil Leifer

In cruelly efficient performance, Ali punished Patterson — who was hobbled by a painful back injury — seemingly toying with the former champ throughout the bout, hitting him at will and calling, "What's my name?" before finally winning on a 12th-round TKO.

James Drake

Capping off a five-fight campaign in 1966, Ali faced Cleveland Williams in the Houston Astrodome on Nov. 14. Known as the Big Cat, the heavily-muscled Williams was a power puncher who had racked up 51 knockouts in 71 fights. But he was also 33, barely recovered from a gunshot wound sustained the year before, and up against a young champion very much in his prime. Ali wasted little time in unleashing a withering attack.

James Drake

Float and sting: In a display of speed and combination punching unmatched in heavyweight history, Ali overwhelmed Williams from the start. The challenger, here down for the third time in round 2, would be saved by the bell before referee Harry Kessler could count him out, but it would only postpone the inevitable.

Neil Leifer

Ali dropped Williams again early in the third round, and Kessler waved the mismatch over at 1:08 of the third.

In a multiple-exposure portrait, Ali demonstrates his signature double-clutch shuffle during a photo shoot in December 1966.

Ali sits in the locker room before his February 1967 fight against Ernie Terrell. Like Patterson before him, Terrell refused to call the champion by his Muslim name. Also like Patterson, he paid a stiff price, as Ali punished Terrell for 15 ugly rounds before winning by unanimous decision.

Outside the Armed Forces Examining and Entrance Station in Houston in April 1967, Ali spoke to the press about his refusal to be inducted into military service. Among those on hand was ABC's Howard Cosell, who would be a staunch supporter of the fighter's stance. The decision cost Ali his boxing license and his heavyweight title, and he was sentenced to five years in prison but remained free pending an appeal.

Neil Leifer

In professional exile for three and a half years because of his draft case, Ali sought to return to boxing in 1970. He began with a night of exhibition bouts at Morehouse College in Atlanta, where before going into the ring, he shared a locker room laugh with actor and comedian Lincoln Perry (right), better known by his stage name of Stepin Fetchit. The friendship between the two black icons would later be examined in an acclaimed play by Will Power, Fetch Clay, Make Man.

Neil Leifer

After the Atlanta Athletic Commission at last granted Ali a license, the deposed champion went back into serious training. He was, as ever, in the capable hands of trainer Angelo Dundee, here wrapping boxing's most famous fists at the 5th Street Gym in Miami in October 1970.

Neil Leifer

With his return to the ring scheduled for Oct. 26, 1970 in Atlanta, against dangerous contender Jerry Quarry, Ali made it clear to all who would listen that he was on a mission to reclaim the title that had been stripped of him.

Neil Leifer

Reel to spiel: For the ever-loquacious Ali, even a rare moment of down time — like this afternoon in 1970 in a Miami hotel room — was a chance to do some talking.

Neil Leifer

Despite Ali's long layoff, his comeback campaign would include no easy tune-up bouts. He stopped Quarry in three rounds on Oct. 26, 1970, then, just six weeks later — an unthinkably short interlude by today's standards — took on Argentine contender Oscar Bonavena in Madison Square Garden. Here, Ali fires a right at the rugged and awkward Bonavena, who took the fight to the former champion all night.

Neil Leifer

After a long, often sloppy bout, Ali — here being held back by referee Mark Conn — produced one of the most dramatic finishes of his career, dropping Bonavena three times in the 15th and final round to automatically end the fight. The win cleared the way for a showdown with Joe Frazier, the man who had taken the heavyweight title in Ali's absence.

Neil Leifer

On the night of March 8, 1971, the eyes of the world were on a square patch of white canvas in the center of Madison Square Garden. There, Ali and Joe Frazier met in what was billed at the time simply as The Fight, but has come to be known, justifiably, as the Fight of the Century. For 15 rounds the two undefeated heavyweights battled at a furious pace, with each man sustaining tremendous punishment. In the end Frazier prevailed, dropping Ali in the final round with a tremendous left hook to seal a unanimous decision and hand The Greatest his first loss in 32 professional fights.

Ali poses with the fight poster for his upcoming fight against Jimmy Ellis during a photo shoot in July 1971. Ellis was an old friend of Ali's — both were trained by Angelo Dundee — and knew his fighting style well from many rounds of sparring.
