Roger Angell in The New Yorker, some years back, had a story about the Mets in spring training. One of the pitching coach's tasks was to observe the ways that the pitchers telegraphed their pitches and then tell them, so as to try to break the pitchers of this habit.
That notion sounds so commensensical that that probably explains why such a duty hasn't been assigned to every major-league pitching coach.
It wasn't long after the Diamondbacks won the Series in '01 that it came out that the Yankees knew Pettitte was tipping his pitches in Game 6 (it might have even surfaced in the accounts of Game 6, but I can't recall precisely). My feeling was, If they knew then, why didn't they tell Pettitte not to tip, for God's sake? It's like the old comedian's line about the guy who goes to the doctor and says, "It hurts when I do this," only to have the doc respond, "So don't do that!" Duh!
