• Do you slice more often than you hit it straight?
• Are you likely to hit pop-ups off the tee?

The Solution:
Practice your backswing with a watch on your left wrist, but before you start, slide a ball-point pen under the face.  Make sure the cap of the pen reaches the middle of the back of your hand. During your backswing, if you feel the cap dig into the back of your hand, you’ve just discovered the cause of your slice.

Slide a pen under a watch to keep you from cupping your wrist.

How so?

This pen drill tells you if you’re cupping your left wrist. A cupped left wrist causes your clubface to rotate wide open at the top. Unless you make a serious compensating move, the face will stay open on your downswing.

How to Fix Your Slice

Continue to practice your backswing with the pen under your watch until you can bring the club to the top without the pen jamming into your hand. Keep your left wrist perfectly flat. A flat left wrist means that your clubface is square at the top, which increases the chance of it being square at impact.

Don’t Over Do It!

If you start hooking the ball after performing the pen drill, you’ll know that you’ve over-compensated and started bowing your wrist. Just remember, keep your wrist FLAT, not bent in either direction.
