Just because your ball curves to the right and misses the target on that side, it doesn’t mean you hit a slice. A slice is a ball flight that starts left of the target and finishes right of it.
But a push fade is a shot that starts right of target and moves further right through the air. If you relate to this and start practicing some anti-slice drills, your shots will get worse!
A push slice comes from a clubhead path that is too much from the inside and with a clubface open to this. The drill from Adrian Fryer in this golf video tip will help get your drives on the straight and narrow.
