In 1893, Armour played for the Kansas City Blues in the Western Association and saw his batting average jump to .280 with 22 runs scored and 14 stolen bases in only 20 games. Armour also returned to Bradford in 1893 to play in 20 games, including the game that won the Monongahela League pennant for Braddock. The use of Armour, a Western Association player, in the game prompted a protest by the Duquesne club that Braddock's pennant be forfeited. The pennant was ultimately awarded to Braddock.
