We were hitting in the batting cage in our garage. The temps in the garage were ~60*F. Outdoor temp was ~30*F
The bat was just brought out from the house, as well as the balls.
DD put a quarter size hole in barrel so a 2013 in a game when it was new. Cracks radiated out around the hole. The warranty replacement was her practice and game bat for quite awhile, and it was my younger dd's game bat last fall, still hot as heck after hitting thousands of balls in practice and games.
