The Illinois-Indiana-Iowa League (also known as the "Three-I" or "Three Eye") was a national force in minor league baseball for the first sixty years of the twentieth century. The Three Eye was the nation's oldest Class B minor league, then the highest level of low minor leagues. Communities represented in the league included Bloomington (Illinois), Cedar Rapids, Danville, Davenport, Decatur, Evansville, Moline, Peoria, Springfield, Terre Haute, Waterloo, and others. The Three-I League is well represented in the halls of the Baseball Hall of Fame. Lou Boudreau, Mordecai Brown, Red Faber, Hank Greenberg, Burleigh Grimes, Carl Hubbell, Red Ruffing, and others played in the league en route to Cooperstown. In addition, many big league stars spent time in the Three Eye, including Hank Bauer, Ossie Bluege, Del Crandall, Carl Erskine, Kirby Higby, Frank Howard, Harvey Kuenn, Allie Reynolds, Charlie Root, Gus Suhr, Eddie Waitkus, Whitlaw Wyatt, and many more.  This in an ongoing research project and much information remains fragmentary at best and overlooked at worst. With the assistance of interested visitors (and perhaps former players), it is hoped that this site will develop into a studied overview of the great Three Eye.
