Attell knocked out Johnny Reagan on December 22, 1904 in seventeen rounds in St. Louis. Though the first nine rounds were close, and Reagan knocked down Attell in the sixth, from the thirteenth through the seventeenth, Attell took the advantage. In the seventeenth, a left and right to the jaw, preceded by a single blow to the chin sent Reagan to the canvas for the full count. In two previous meetings at St. Louis's West End Club, Attell had won in a close fifteen round points decision in St. Louis on December 15, 1904, and in an eighth round points decision the previous month.
