His biggest role in baseball history began in 1907 when as owner and manager, Dunn used his superior player-evaluation skills to build a minor league baseball juggernaut in Baltimore. Dunn’s Orioles won 27 games in a row at one point, and were considered equal to the major league teams of the day. The Federal League’s arrival in Baltimore forced him to sell off 12 of his Orioles, including a pitcher named George Ruth. Dunn got a very good price for Ruth, and called him his “$10,000 babe”—a nickname, and a legend, was born. Over 22 years, Dunn led his Orioles to an Eastern League pennant and seven consecutive International League pennants, while compiling a 1,959–1,408 record. He served as owner/manager until his sudden death in 1928.
