What Is The Definition Of Secondary Lead In Baseball?
1. 
A secondary lead in baseball is when the baserunner takes a few steps or moves towards the next base after the pitcher has begun to make their delivery to home plate. The purpose of taking a secondary lead is to give the baserunner some momentum in case the batter puts the ball into play. Some advantages that a secondary lead can give an offense is that it increases their chances of beating out a double play and it makes it easier for them to advance a base after a passed ball.
