The shortstop is a source of stillness at the centre of the defense. He projects this stillness and his teammates respond.
To field a ground ball must be considered a generous act and an act of comprehension. One moves not against the ball but with it. Bad fielders stab at the ball like an enemy. This is antagonism. The true fielder lets the path of the ball become his own path, thereby comprehending the ball and dissipating the self, which is the source of all suffering and poor defence.
There are three stages: Thoughtless being. Thought. Return to thoughtless being.
Do not confuse the first and third stages. Thoughtless being is attained by everyone, the return to thoughtless being by a very few.
— Chad Harbach, from The Art of Fielding
