You're Correct!

You have an out to in swing path and your face is aiming right of the direction of the swing path but left of the target when you strike the golf ball.

If you have got a slice this means that your ball flight, when you have hit the shot, is starting to the left of the target, but then it is curving to the right, finishing on the right of the target. This ball flight is purely caused because your club head does not swing directly along the target line, with your club face aiming down that target line. If you want to hit a straight shot you need to get the club head travelling directly along the target line with the face aiming in that direction and you will hit a shot straight at the target.

If you put an alignment pole on the floor to represent the target line, the far side of that line is called the outside of the target line and the side that you are standing on, is called the inside. As you swing the club head towards the golf ball on your down swing, if you are hitting a slice, the club head is travelling too much on the outside of the target line, it is on the far side of the target line and approaching from that side, which means that you then have to pull the club head towards you to get it to strike the ball and because you are pulling the club head across the target line, you will continue that action and the club head will move on to the inside of the target line.

If your club face is aiming to the right of that direction of travel, but to the left of the target, you will now put tilted axis spin on to the golf ball because there is a difference between the direction that the club head is travelling in and the direction that the club face is aiming in and that will now put a left to right spin on to the golf ball and you will see a curve in the ball flight.

To correct this movement, you need to block the far side of the target line so that you are unable to swing in from that direction. Take one of the range baskets, just pour the balls out of it and turn it upside down. Place it about a foot to the right of the ball and a few inches on the far side of the target line, so that you can swing the club back along the target line without connecting with it. You are going to use it so that as you swing back down towards the golf ball you do not hit the basket, but you swing inside the basket towards the golf ball. Try this swinging slowly at first and without the golf ball and if you do hit the basket initially, do not worry about it, the fact that you have hit it will just give you the information that the club head is on the outside of the target line and that is what is causing your slice.

Set that basket up in the position discussed and take a few practise swings without the ball, just to get used to swinging back and then back down without hitting that basket. As you do this, work on swinging the club head on the inside of the basket and concentrate on keeping the club face aiming at the target as you do it. Once you start to then feel more confident with this, pop the ball back in and start to swing slowly, working on making sure you do not hit the basket, that you are swinging inside the basket with the club face aiming at the target.

Working on this will really help you to improve your golf shots and eradicate your slice and you will start hitting straighter golf shots.

Aiming left on its own is not enough to cause a slice. This will promote you to swing the club head on an out to in swing path, but if the club face is square to this and where you are aiming, you will hit a straight golf shot, but a straight left of target golf shot.

An open club face through impact, on its own, is not enough to produce a slice. An open club face will result in the golf ball flying high and to the right of the direction that you were swinging the club in. A slice starts left of target and finishes right.

If you are swinging the club head along the target line, with an open face, the ball will start right of target and finish further right.
