Today I went to the range to hit some balls. I was hitting all of my shots relatively well, until I began to hit some short shots with my sand wedge. Every time I did I would either shank it, top it or hit behind it. I tried to slow down my swing, speed it up, delay at the top, etc., but nothing seemed to work. I moved the ball back in my stance, then forward, but this didn't help either. I was hitting off hard, short grass; could this have been part of the problem? Could I have been subconsciously decelerating through the shot?? Any suggestions would be appreciated.
