Joe Frazier vs Oscar Bonavena II

On December 10, 1968, Joe Frazier and Oscar Natalio Bonavena squared off for the second time in their professional careers, this time at the Spectrum in Philadelphia, Pennsylvania. This bout came after their first encounter at Madison Square Garden on September 21, 1966, where Frazier won a 10-round split decision. The rematch was set for 15 rounds, with Frazier defending his NYSAC World Heavyweight Title for the second time.

Frazier, weighing 203 pounds, faced Bonavena, who was slightly heavier at 207 pounds. Despite Bonavena's awkward and robust fighting style, Frazier was favoured 3-1 and managed to retain his title through a unanimous decision, with scores from the officials reflecting his dominance throughout the fight: Referee Joe Sweeney scored it 70-67, while judges Dave Beloff and Nate Lopinson scored it 72-64 and 74-64, respectively. The unofficial scorecards from AP and Ring Magazine also sided with Frazier, marking a clear victory for the champion.

The fight was noted for its roughness, with Bonavena warned for low blows in multiple rounds and losing the eighth round by penalty due to foul play. Despite the challenges, Frazier's relentless attack opened cuts over Bonavena's eyes and nose and inflicted visible damage on the challenger's face. Bonavena, employing a peek-a-boo defence for much of the fight, aimed to land a decisive blow but could not match Frazier's pace and power.

The financial stakes for this bout were significant, with Frazier earning $100,000 and Bonavena $75,000 tax-free. However, Bonavena's negotiation for all revenue from South American radio and film rights and his expenses likely resulted in a higher overall payout than Frazier's. The event attracted approximately 8,100 spectators, generating a gate of $206,000.
