Interesting story for baseball fans and computer geeks at http://www.eweek.com/article2/0,1759,1733090,00.asp.
This article describes how Dave Roberts of the Red Sox, with access to the Sox's video on-demand archive available in the clubhouse, asked Billy Broadbent, who handles video systems for the Red Sox, to queue up footage of New York Yankees reliever Mariano Rivera pitching from the stretch with a man on first base. Roberts studied Mariano Rivera's first base move on video two innings before he was to be inserted as a pinch runner. Most of the piece is about the technology, but it is an interesting insight into the most important stolen base in Red Sox history.
