Have been batting well in the nets and have come along in the last few sessions, however, I've been told that I have a problem with the way I hold the bat. Simply, when I play a shot, particularly a drive or defensive, my bat wants to come closer to my legs (i.e. the bat ends up at a slight / angle when the shot is been executed).This often leaves me edging or mi****ting shots which, if the problem was corrected, would be good shots. I have tried to adjust my grip but still find I have the problem. Any tips?
