1971-02-12 Ken Buchanan w pts 15 Ruben Navarro, Sports Arena, Los Angeles, California, USA - WORLD. Referee: Arthur Mercante. Scorecards: 9-2, 9-4, 9-4. Overcoming a shaky start when he suffered a body pounding, Buchanan (134½) came back strongly with the left jab and solid rights over the top to gradually take the play away from his rival. By the sixth Buchanan was setting Navarro (135) up with scintillating left hands, and although the latter was always dangerous with his body shots, being well in the fight until the 11th, at that point the champion took over.
Buchanan forfeited the WBC version of the title in June due to a contractual dispute. Having been told that he must defend against their stipulated challenger, he signed for a return against Laguna, an action which was followed by the WBC matching Pedro Carrasco, the reigning European junior welterweight champion, and the former champion, Mando Ramos, for their version of the title. Since losing his title to Ismael Laguna, Ramos had beaten Sugar Ramos, Raul Rojas and Ruben Navarro.
A veteran of 106 contests, the 28-year-old Carrasco had avenged his only defeat at the hands of Aldo Pravisani three times over. He had also beaten Rene Roque (twice), Borge Krogh, Franco Brondi, Kid Tano, Olli Maki, Angel Robinson Garcia and Joe Tetteh. With a high guard, fast left jab and good movement, Carrasco was strongly fancied.
