And why does it get worse as the round progresses? I can keep my drives pretty straight when I take off some force. I end up getting about 225 off the tee. But somewhere around the 11th or 12th the same swing sends my ball about 10 yards off line. Does it have to do with being too loose and how do I correct it? I've been working on solidifying my grip and it helps but it's not the entire answer.
