QuesTec

QuesTec is a digital media company known mostly for its Umpire Information System (UIS) which is used by Major League Baseball for the purpose of providing feedback and evaluation of Major League umpires.

The QuesTec company, based out of Deer Park, New York, has been mostly involved in television replay and graphics throughout its history. In 2001, however, the company signed a 5-year contract with Major League Baseball to use its pitch tracking technology as a means to review the performance of home plate umpires during baseball games. The contract has continued through the 2008 season by annual extensions.

The Umpire Information System

The UIS system consists of four cameras placed around a ballpark that feed into a computer network and record the locations of pitches throughout the course of a game. Two of the cameras are located high in the stands above the 1st and 3rd base lines to track the trajectory of each pitch. The other two are located at field level and record the stance of the batter so the top and bottom of the strike zone can be set. Computer software then generates CDs that umpires and MLB executives can review and learn from. These CDs include video of the pitches as well as graphic representations of their locations plus feedback on the umpires' accuracy. The UIS was featured in a 2002 segment of Scientific American Frontiers called [http://www.pbs.org/saf/1206/segments/1206-3.htm "Baseball Tech"] When first introduced, controversy over the Umpire Information System quickly developed as umpires and players alike voiced concern over the system's accuracy and the fact that limited deployment (6 parks in the first year) might not guarantee uniform umpiring in the remaining parks. In its early trial period, baseball analysts questioned whether QuesTec was producing the consistency in umpiring that was supposed to occur. [Nate Silver and Keith Woolner, "QuesTec Not Yet Showing Consistency from Umpires," ESPN.com (June 5, 2003) [http://proxy.espn.go.com/mlb/columns/story?id=1563505] .] A report by a QuesTec operator a year later suggested that the system still needed to be tweaked. [Jason Karegeannes, "Confessions of a Questec Operator: How the System Works, How It Can Be Improved," Baseball Prospectus (Aug. 10, 2004) [http://www.baseballprospectus.com/article.php?articleid=3326] .] The controversy was fueled, in part, by several attempts by the World Umpires Association (WUA) to have the system removed through legal action, culminating in a dispute filed with the National Labor Relations Board (NLRB). Meanwhile, a more hands-on approach was taken by former Arizona Diamondbacks pitcher Curt Schilling. Schilling used a bat to smash one of QuesTec's field cameras; an act that led to a fine for the pitcher. The NLRB grievance was dropped by the WUA as part of the contract negotiations with MLB after the 2005 season, ending the legal challenges to the system.

As the UIS controversy died down and the statistics accumulated, it became clear that the UIS was accomplishing its basic goals of narrowing the strike zone closer to the width of the plate and returning both lower and higher strikes that were typically not called before the system was introduced. In addition, the claims that the system would "ruin the game" have not been fulfilled as both pitching and hitting statistics in "QuesTec ballparks" have been as good or better than non-QuesTec parks. [David Gassko, "The Outside Corner," The Hardball Times (February 1, 2007) [http://www.hardballtimes.com/main/article/the-outside-corner/] .] As of the end of the 2007 season, the system has analyzed more than 4000 games.
