Pitching finish matches full swing after impact
The position of the club in the pitching finish is a great rehearsal for where the club should be after impact on your full shots. In both cases, for the swing to be on plane, the shaft should be pointing at the target line and the clubhead should be slightly inside the target line. When the shaft and clubhead point outside the target line, you've made an inside-to-out swing and likely either hooked or blocked the shot. When the clubhead is inside, you've swung out-to-in and sliced or pulled.
