- Undisputed World Middleweight Title
- Rodriguez knocked out with single left hook.

"World middleweight champion Nino Benvenuti, his face a bloody mask from the 3rd round on, retained his title Saturday night with a stunning knockout of American challenger Luis Rodriguez in the 11th round. The end came at 1:10 of the 11th in a fight Rodriguez seemed sure of winning. The 32 year old challenger had cut Benvenuti's face open with slashing right hooks and counter-punching left jabs that left Benvenuti glassy-eyed. But Benvenuti came back with one sudden shot - a tremendous left hook - to Rodriguez' face. The challenger fell back and took the full count almost unmoving. A crowd of 18,000 erupted in wild cheers and fought its way into the ring to raise Benvenuti into the air. Rodriguez remained semi-conscious in his corner." -United Press International
