The best system for determining which way the ball will travel for you on sidehill lies is to try ten practice balls from each sidehill position and see what really happens. When making a practice stroke, the player should concentrate on how hard the putt must be hit and then duplicate that stroke when making the actual putt.
The long grass will decrease the loft of these clubs and the ball will actually go the distance of the less lofted fairway woods. Around the green, the player must again use a more lofted club. These types of shots are custom made for a wedge or a 9-iron. The effect of the long green will once again decrease the loft of the club. The ball will therefore fly lower and run more than if it were in the fairway.
Take a practice swing and note where the club is striking the ground. If the club is striking the ground nearer the back foot, move the ball back in your stance; if the club is striking the ground nearer the front foot, move the ball forward in your stance. This system is the most accurate system to determine where the ball should be placed in the stance.
On sidehill lies, position the ball left center. If the ball is above your feet on the sidehill lie, you will normally hit the ball straight or pull it to the left. If the ball is below your feet, most players will actually pull the ball to the left because their leg action will slow down as they try to maintain their balance.
Therefore, the best approach is to play the shot you know you can play. When hitting over a tree, take one club extra. If you think you can clear the tree with a 7-iron, take an 8 or 9 iron. If you think a 5-iron will just stay under those branches, hit a 4 or 3 iron. This approach simply gives the player the benefit of the doubt and will take pressure off your shot.
In addition, golf putting is a matter of combining the distance of the putt and the direction of the putt. For the most part, the direction will be fairly automatic. Rolling the ball approximately on line is fairly automatic for even the newest golfers, bur hitting the ball the right distance is an acquired talent that takes time and practice.
So, never feel nervous when you meet trouble shots. Just try your best and consider of the tips above. They will be very useful!
