Branch Rickey had the best technical baseball mind in history and phrased ideas and exhortations with enough eloquence to qualify as the game’s Winston Churchill.
At about the same time I read A THINKING MAN'S GUIDE TO BASEBALL, I also read a book by Rickey entitled THE AMERICAN DIAMOND. Ballplayers would do well to read it, particularly the section on the Rundown play which I have never seen correctly executed.
