Detroit Wolverines Leadley served as the Secretary of the
Detroit Wolverines baseball club from 1884 to 1888 with principal responsibility for handling the club's finances. He was also the head of the Cass Club baseball club in Detroit. Leadley managed the team for the last 38 games of the season and compiled a 19–19 record. At the end of the 1888 season, the Detroit Wolverines left the National League, and most of the players were sold to other clubs. A new
Detroit Wolverines team was formed for the 1889 as part of the
International Association. Leadley served as the Wolverines' manager in 1889 and 1890. The 1889 Detroit club compiled a 72–39 record, He continued to manage the Detroit team until it disbanded part way through the 1890 season.
Minor leagues and civil service In August 1891, shortly after being removed as Cleveland's manager, Leadley was hired as manager of the
Omaha, Nebraska club in the
Western Association. At the time, the
Omaha Daily Bee wrote: "In Manager Leadley Omaha has a manager she can feel proud of. He is an educated, cultured gentleman, and ranks high in the estimation of the base ball world." In April 1892, Leadley was hired as manager of the Buffalo team in the Eastern League.
The Sun newspaper from New York wrote at the time: "In Bob Leadley Buffalo has secured a shrewd and able manager." However, a short time after the announcement, Leadley stated that he would not move to Buffalo and would keep his position in Detroit with the United States internal revenue office. Leadley remained in the civil service in 1893 and 1894. He served as the assistant cashier at the revenue office during those years.
Team owner in Seattle and Grand Rapids In 1896, Leadley formed a partnership with
Bob Glenalvin, manager of the
Detroit Tigers in 1894, and others to re-establish the
Pacific Northwest League as the
New Pacific League. Leadley became the owner of the
Seattle Yannigans/Rainmakers franchise and hired
Count Campau, who he had managed in Detroit, as Seattle's player/manager. However, the league folded by the middle of June 1896. After the collapse of the New Pacific League, Leadley returned to Detroit. The two owned the team, known as the
Grand Rapids Bob-o-links, during the 1897 season and hired Count Campau as player-manager with Glenalvin playing at second base. Late in the 1897 season, Leadley bought Glenalvin's interest and became sole owner of the club. ==Embezzlement and fugitive==
