"the Fitzsimmons Act" - The Moorhead Independent refers to the Moorhead team as doing the Fitzsimmons Act in two wins against Wahpeton-Breckenridge in late May. This is likely a reference to British boxer Bob Fitzsimmons, who had just completed a marathon win against the American heavyweight champion Jim Corbett in March. The use of the term was also fitting considering the fact that the W-B manager was named Ed Corbett.
