Muhammad Ali vs. Oscar Bonavena

For the first three rounds it was a vintage Ali repelling the brave but crude Bonavena.[17] José Torres, who witnessed the bout, wrote that in the first round of the fight Ali looked like a bullfighter and Bonavena like a bull.[18] Torres went on to write:

Now it is the third round and Ali begins to do exactly as he did in the previous two rounds. He moves and flicks left jabs. Oscar also does exactly as he did in rounds one and two, he charges, sometimes with control, most times with anger. One thing he does which I think many of us so-called smart fighters never do: he misses and keeps trying. He misses some more and keeps trying. He doesn't get frustrated.[19]

In the middle of round 4, Ali began to tire and retreated to the ropes; Bonavena now had a stationary target to hit. From rounds 4 through 8 of the fight, Ali continued defensive boxing with Bonavena stalking him relentlessly. Leaning back against the ropes, Ali started depending on his reflexes rather than his feet to avoid Bonavena's punches. However, the body shots Bonavena was throwing at Ali started connecting with some regularity. The fight became insipid with Bonavena pursuing Ali, but lacking the requisite technique to end the bout.[17]

Prior to the match, Ali had predicted that round 9 would be the final round of this bout. As it turned out, both fighters kept punching each other throughout this round. The round began with Ali landing a strong punch on Bonavena's jaw, but as Ali moved in purposefully, the bout became a slugging contest with Bonavena hitting back. In the melee, Bonavena's hook found Ali's jaw, and Ali was hurt.[17][20][21] Reflecting on this moment in the fight, Ali later observed:

Funny, when i was predictin' the ninth round, I never thought I came close to predictin' on myself. I made a lot of mistakes in that fight, and it cost me. I got careless with him in the ninth round, and you can't do that with Oscar. In that ninth round I got hit by a hook harder than Frazier could ever throw. Numb! Like I was numb all over. Shock and vibrations is all I felt, that's how I knew I was alive. I mean, I was jarred. Even my toes felt the vibrations. The first thought that came to mind—another good one or two might have dropped me. So the minute I'm hit—two steps backwards and I'm on the other side of the ring."[17]

After the fiercely contested ninth round, the fight degenerated into an insipid affair with Ali engaging in defensive boxing.[17][22] As Torres wrote:

In the ring there is no action. People boo Ali. He's causing the dullness of the fight. He is also preventing Oscar from connecting solid blows ... Round eleven finds Ali leaning against the ropes. Oscar is throwing awkward punches to Ali's body ... It goes on like that. The thirteenth is like the twelfth and the fourteenth like the thirteenth.[22]

In the final round of the bout, Bonavena, realizing that he needed a knockout to win the match, started throwing a barrage of punches at Ali. As Bonavena was preparing to throw a right at Ali, he was suddenly beaten to the punch by Ali's left hook and knocked down. Bonavena got up and was knocked down again; he got up a third time and was again knocked down by Ali after which the fight was stopped.[17] Bonavena's trainer Gil Clancy remembered:

[B]y the fifteenth round, believe me, they were like two Golden Gloves kids. Whoever hit who, the other guy was gonna go. That's when Ali threw a left hook. His head was looking up toward the balcony somewhere, and he threw a left hook, hit Bonavena on the chin, and knocked him down. Bonavena got up, but he was out on his feet. Ali knocked him down three times that round, but after the first knockdown it was academic.[21]
