University of Colorado head coach Jesse Mahoney demonstrates a warm-up drill that he calls pin-to-pin pepper.
The rules of the drill can be changed to suit your needs for the day. For example, hitters may only be allowed to swing at 75% or middle hitters can only hit transition balls. This forces the players to focus on the different strategies the rules ask, while getting a good warm up in.
The drill also works on base to read transitioning, making the players focus on communicating in transition and getting back to base before the next play begins.
