Looking back at my 2021 golf season, I found that I had rounds where I struggled to control my ball flight. This error was generally traced back to the position of my clubface during impact. I know this because my misses are generally left (or way left sometimes) and when I look at my clubface afterwards, I found that it was closed. This challenge would come and go during my rounds and I often wondered what was the cause. Well, I think I found out my error and I thought it was worth sharing.
