�The one thing that would make the game faster would be to call a strike on a high fastball down the middle,� Hershiser said. �Calling that pitch would change every at-bat. Right now, that pitch has no chance of being called a strike.� The �high, hard one� that became an American idiom is ball one, despite the written rules. In 1969, the top of the strike zone was moved from the shoulders to the armpits; in 1988, the upper limit became the �horizontal line at the midpoint between the top of the shoulders and the top of the uniform pants.� (It had moved downward informally when umpires switched to more compact chest protectors in the National League in the 1950s and in the American League in the 1970s because the umpires were able to crouch lower.) In the mid-1990s, umpires more frequently gave pitchers calls off the outside corner than up in the zone. The complaint about high strikes dates back decades. In 1987, Peter Gammons wrote in Sports Illustrated that calling those long-lost high strikes would speed up ballgames. He quoted Pete Rose saying, �The major reason that games are so long and boring today is the strike zones are so damned small.� The recent marathons between the Yankees and the Boston Red Sox are a testament to the idea because both teams are devoted practitioners of working the strike zone. The games of their first series to open the season were so long that the teams were admonished by the umpire Joe West. Heading into Sunday�s game, the matchups between the Yankees and the Red Sox this season have lasted an average of three and a half hours. Over all, today�s games feature about 27 more pitches than in 1988 (the oldest official pitch counts), equal to nearly an extra full inning of play � although stronger players, smaller ball fields and tighter baseballs also give pitchers more incentive to work around the strike zone. http://www.nytimes.com/2010/08/09/sports/baseball/09highstrike.html?ref=sports And why is it taken for granted that the strike zone is an expression of the umpire's personality?
