When Spring Training begins, camp is filled with ballplayers of all levels. They are divided into major league and minor league camps and begin their drills. Some of the more touted minor league prospects are invited to major league camp to give them experience and allow coaches an opportunity to evaluate talent.
As Spring Training moves forward and games begin the starters get their work in early before leaving the game to the younger players. For fans unfamiliar with this concept it is strange to see the team’s regulars leaving after just a few innings.
