Peasley played Major League Baseball for the Detroit Tigers in September 1910, appearing in two games and compiling a 0–1 record with an earned run average of 8.10 in 10 innings pitched. There was some concern in 1911, that his career would end due to the increase of muscle mass to his arms from working with an axe during the previous winter, though would never again pitch in the majors.
In 1911, The Buffalo Times reported that he "may be one of the Buffalo club's pitchers this season" but he did not play professional baseball that year. In April 1912, he was reported to be "making a good impression ... with the Vancouver team" but only played in that season for the Winnipeg Maroons of the Central International League.
