Coach's tip: Break a composite fastpitch bat in gradually — 100–200 controlled swings off a tee and soft toss, rotating the barrel slightly between hits, before live BP — so the barrel reaches full performance. Keep composite bats out of cold weather (below roughly 60°F) to avoid cracking, store them indoors at room temperature, and wipe them down after each session to preserve the finish and grip.
