From baseball hall of famer Christy Mathewson's Pitching in a Pinch, originally published in 1912:
In minor leagues, there are fewer games in which a "break" comes. It does not develop in all Big League contests by any means. Sometimes one team starts to win in the first inning and simply runs away from the other club all the way. But in all close games the pinch shows up.Tags: Baseball, pinch, pitching, Christy Mathewson
It happens in many contests in the major leagues because of the almost perfect baseball played. Depending on his fielders, a manager can play for this "break." And when the pinch comes, it is a case of the batter's nerve against the pitcher's.
