Baseball historian Glenn Stout has written previously about the Boston Red Sox's historic sale of Babe Ruth to the New York Yankees following the 1919 season.
In Red Sox Century and this 2004 ESPN article, Stout presented a deep understanding and an accurate portrayal of an event that has for decades been the subject of rumour, conjecture, and outright falsehoods.
Stout's book-length treatment of the subject, The Selling of the Babe: The Deal That Changed Baseball and Created a Legend (Thomas Dunne) is a well-researched and entertaining account of what still stands as baseball's most famous transaction.
