At the beginning of the 1909-1910 Pennsylvania League season, Kensington's Hibernians, the reining league champs, seemed a sure bet to repeat as champions. But the Tacony team had other ideas. Led by what the Philadelphia Inquirer described as "the splendid half-back line" of team captain Hector McDonald, former Scotland junior international Robert Morrison, and Percy Potts, the Tacony team defeated the Hibs 2-0 on October 23, 1909.
