20 March Charley Phil Rosenberg w pts 15 Eddie Martin, Madison Square Garden, Manhattan, NYC, New York, USA - NY. Referee: Patsy Haley. Amazingly, Rosenberg (116) took off 39lbs in a few weeks before coming into the ring and then surprised Martin (117) by winning the unanimous decision and taking the title. Allowing the champion to make a reasonable start and having taken a good look at him, Rosenberg pushed on in the fifth, with left jabs to the face and countering hooks to the body opening Martin up. Growing stronger as the fight progressed, the challenger began to control the fight completely and after Martin had run out of ideas there was only going to be one winner. Although The Ring magazine continued to refer to Rosenberg as a ‘mythical’ champion, in June both the IBU and NBA announced that they recognised him as the titleholder and expected him to defend against the best men available.
