If you spend most of your round scrambling from off the green, you need to work on your approach shots. These are shots coming in from 80 to 150 yards away. If you can get it on the green instead of landing in the bunker or rough it will save several strokes a round. Here is 2 golf instruction tips to help you land on the green more often.
Golf Instruction Tip #1: First thing is to aim for the middle of the green. When I am struggling getting on the green more often than not it's because I am aiming for the flag. This alone will having you hitting more greens on a consistent basis. More than likely if you aim for the pin you will end up over the green because you are not putting enough back spin on the ball.
Golf Instruction Tip #2: Second, check your alignment. If you are aiming for the middle of the green and you are still missing it, more often than not your alignment is off. Practice your alignment!
Generally, when you are off the green it is due to alignment, not distance. Most golfers have a 160 yard club, 150, 140, 130 or whatever, so most of the time alignment is the problem. If your alignment is correct and you are aiming for the middle of the green even if you hit a poor shot, the ball may go a little deeper or come up short. But even if when happens, most greens are big enough that you should be on the putting surface. Practice these two things the next couple of rounds and you will see the difference on your score card.
