Coach's tip: Break the barrel in with 100–200 controlled swings off a tee and soft toss, rotating it slightly between hits, before live at-bats so the composite fully loads. Protect composite bats from cold weather to prevent cracking, store them indoors at room temperature, and wipe them down after each use to keep the finish and grip in peak condition through the season.
