1963-06-01 Willie Pastrano w pts 15 Harold Johnson, Convention Centre, Las Vegas, Nevada, USA - WORLD. Referee: Jim Olivas. Scorecards: 69-68, 69-67, 68-69. Having spent most of his career fighting heavyweights, Pastrano (174) made the most of his opportunity and at the final bell the split decision in his favour saw him finally become a champion. For the entire contest, Pastrano jabbed and moved while the counter-punching Johnson (173½) failed to take the fight to the challenger. On two occasions, in the fifth and 13th, the harder-punching Johnson had Pastrano at his mercy after landing heavy rights to the jaw, but he failed to follow up and the latter was able to recover. It was the higher work rate that won the fight for Pastrano and at the finish he was unmarked while Johnson finished with a badly swollen nose and damage to his left eye.
At the beginning of August, when Pastrano refused to meet Henry Hank (now fully fit), the Michigan Boxing Federation decided to hold their own version of the championship and brought in a leading contender, Eddie Cotton, to face the local man.
Meanwhile, Pastrano took in three non-title bouts, losing to Gregorio Peralta on points over ten rounds at The Auditorium, Miami, Florida on 20 September in one of them.
In January 1964, Angelo Dundee, Pastrano’s manager, was reported to be negotiating a title fight against Peru’s Mauro Mina, who had come through a successful detached retina operation and had been given the all-clear by the doctors. The prospect of that fight coming off quickly did not seem too good, but a few weeks later, with pressure from the authorities to defend or be stripped, Pastrano signed for a defence against Peralta.
