Played with Mark, my mailman. Very hot and humid. I seem to have lost my driver swing. Started okay, but kept trying to find the distance I have had and ultimately screwed something up. By the 10th hole I was so out of sorts with my driver swing, I nearly topped it off the tee. I totally blew up on that hole after that terrible drive. Started to find something late in the round but it was too late by then. Not sure, but yesterday's thick rough tweaked something in my left shoulder and it may have been partially responsible for my poor driver swing today. Lots of shoulder discomfort. Iced as soon as I got home. And then an hour later. Taking a day or two off.
