But the more significant influence has been on the increased use of data analytics to change how baseball and other sports are being played and how players are being trained and coached. In baseball, for example, starting pitchers now pitch fewer innings because statistics revealed that relief pitchers are more likely to get batters out after their third time at bat. Detailed maps of where players have hit the ball are used for “shifting,” repositioning fielders often dramatically to the left or to the right, closer up or farther out, when a particular batter steps up to the plate.
