“Volpe’s on deck.” Matt Hyde, a Northeast area scout for the Yankees, used to send that text to his colleagues, crosscheckers and superiors whenever Anthony Volpe stepped to the plate. The messages, which began during a tournament in Jupiter, Fla. during the Fall of Volpe’s senior year of high school, also included the name or number of whatever field his game took place on. They served as an alert: Something exciting is about to happen.
