In the words of former American League umpire Nestor Chylak, umpires are expected to "be perfect on the first day of the season and then get better every day." Forced to deal with sullen managers and explosive players, they often take the blame for the failures of both. But let's face it--umpires are only human. For well over a century, the fortunes of Major League teams--and the fabric of baseball history itself--have been dramatically affected by the flawed decisions of officials. While the use of video replay in recent decades has reduced the number of bitter disputes, many situations remain exempt from review and are subject to swirling controversy. In the heat of the moment mistakes are often made, sometimes with monumental consequences. This book details some of these more controversial calls and the men who made them.
