for sure the face is closed
If you make the path go more left, the ball is either just going to stay there, or the clubface will go a little more left relatively - resulting in a pull rather than a hook.
E.g if his stats are
making him change his path will lead to stats such as
clubface -5 (or worse)
ball is still going left. Sure his path may be a problem, but it is not the reason for his left shots. He doesnt look overly in to out to me (although almost impossible to tell with just DL video, I have a good instinct for it)
Did you read his post after mine!!! He said his ball starts straight then goes left. Path would be in to out with a square face to the TARGET. Yes I know the face is closed to the PATH. The ball will only go left if he is turning his hands over through impact.
