I had a nightmare weekend with my swing and was hitting every iron low and left. I was trying everything to no avail. I spoke with the pro that I take lessons with and he told me I was coming over the top and slamming the club face closed and de-lofting the club. I finally got the hang of what I was doing and started to strike the ball better and wrote my notes down for any future bouts with this. Has anyone had a swing fault show up out of the blue like this? Not really sure what caused it but it threw me for a loop. I have a feeling I started to try to hit the ball harder instead of swinging faster.
