John McGraw was one baseball’s greatest managers and one of New York’s most celebrated figures. He could be charming and generous. Alternatively, he often found himself in the middle of physical confrontations and bitter controversies, frequently from his abuse of the umpires. The details of many of McGraw’s clashes with the umpires can now be unearthed in the massive Garry Herrmann collection at the Baseball Hall of Fame, only relatively recently organized and processed for researchers to use. Levitt combed these reports to find the umpires’ descriptions in their own words of their confrontations with McGraw and their consequences. These include first-hand accounts of incidents from Bill Klem and Bill Byron. Levitt sheds new light on McGraw’s complex personality and Deadball Era baseball.
