To get spin when you hit the ball, here are a few tips. Make sure you have clean grooves as you need a crisp strike, you will also need to hit down on the ball to compress it. But the easiest way to get lots of spin, a good wedge (Titleist spin milled) and a good ball (pro v 1)
Other good wedges are available, but look for ones with deep grooves and a spin milled face. Other good balls are also available, but ideally one which is high spin.
