1901-10-30 (130lbs) Martin Duffy w pts 10 Art Simms, Light Guard Armory, Detroit, Michigan, USA. Referee: George Siler. In what was Simms’ first defeat as a professional, Duffy, who did most of the leading in a very fast contest, was reckoned to have landed twice the amount of blows to that of his opponent. Duffy got to Simms’ jaw repeatedly, having him extremely groggy in the third round before settling for the points win.
On 16 January 1902, it was reported in the Toronto Daily Mail that Duffy should now be recognised as the world 130lbs champion after outpointing Simms in a match made at 135lbs. On the basis of that, one can only assume that Duffy scaled below 130lbs. However, in their return match at the Twentieth Century AC, Detroit on 21 January 1902, which was again made at 135lbs, both men were 140lbs. Following that, Duffy, who won on points over 15 rounds, was soon fighting at that poundage.
