You should never get set over the ball and then aim your putter face. If you do it in that order, you can easily lose sight of your intended line. Instead, aim the face down your line first, then settle your body into position.
When I'm swinging the club at my best, it's because I'm not thinking about mechanics at all. I feel like my body is loose. My arms are soft in front of me when I'm setting up, and my chest and shoulders feel as if they can move and turn easily.
Some players like to change clubs around the green to hit high or low shots. I play all of my short-game shots with my 54-degree sand wedge and change my ball position to hit it higher or lower. I think it's easier to learn one club than four.
Ball position is everything in iron play. If you aren't careful about it, you can create some major problems in your game just by getting an inch or two off.
Grip pressure - not mechanical flaws - is the biggest factor when you're nervous. You unconsciously grip it tighter, which keeps you from making a smooth swing with a natural release. Keep your grip pressure light, and you'll be surprised how much your mechanics stabilize.
Contours on the second half of a long putt have more impact on how the ball rolls because it's going slower. Adjust your speed if that last part is playing uphill or downhill. Don't get fooled by an early slope or break.
When you're hitting a fairway wood, you've got a lot of real estate to cover to get to your target. Your first instinct is probably to give it a little more power because you're worried about coming up short.
Because of the grass and open face, I take one more club for shots from the rough, unless the ball is sitting on top of dry grass. Then, I use more loft and swing softer, trying to hit it about 70 percent to avoid a flyer over the green.
Before you take your address, while you're still reading the putt, imagine the ball tracking on the line you've chosen and falling into the cup. If you don't believe you can make every putt, why bother trying?
