On tee shots, I employ a simple technique to avoid coming at the ball from over the top or from the outside. I place the logo of the ball on the rear inside quadrant and above the midpoint (so that I can see it). Then, I try to “hit the logo.”
Obviously, a hit from 45° inside would result in horrible ball flight, but you’d have to be a contortionist or have a very peculiar swing to actually hit the logo. Instead, trying to hit the logo forces a swing from the inside, more on plane. If you’re hitting a shot that starts straight and slices, give this a try and you may soon be hitting a nice solid draw off the tee.
