Weber, who is listed as a "baseball operations coaching assistant" in the Yanks' 2014 media guide, is the man who sits in front of monitors at every ballpark the Yanks play in, watching everything. If he sees something worth challenging, he calls the phone devoted to replay that's in every dugout. Pena generally will answer. If Girardi or Pena thinks he sees something, either one calls him. All of this has to happen in the narrow window of time before the next pitch or play, according to baseball's replay rules.
