The idea with the early work is to set the baseline for the season. By getting in one-on-one time before the rest of the crew comes into camp, the hitters can close the gap of advancement.
There will inevitably be some tweaks with certain players needing to show more power, some need to show more patience, and others need to continue the development process.
