Make sure the ball is at the sweet spot of the bat. 32 inch bat ball is at 28 ". Plus as Tim stated. Many drills. If you roll your wrists early, it will punish you! Make sure at the beginning they have a helmet! I use 3/8 inch rope. I made a bunch this weekend. Cut bat at 14 ".
Bottom line if you don't have a good first move you cannot hit a ball off the T.
so for a 34" bat would the ball have to be at 30"? thanks!
