Day two of high school state finals on the 15th hole was by far the worst/stupidest thing I've ever done. After day one I was one shot off the lead and our team was leading. I was even on the round, down by one, going into the 15th with a couple possible birdie hole coming in and sprayed my drive a little right into the trees. I had a great line on the ball but none of the people who were following us saw it come down. After a couple minutes of searching my playing competitor said he found it. He knew the ball I was playing, a Titeilst 2 with our school logo on it. When I looked at the ball it was the same type and brand of the ball I was playing and the logo would have been down. Didn't think anything of it and hit a great second shot into the green to about 10 feet with the other player having about 20 feet for his birdie. I knew this was a great opportunity to get the shot back and be tied going into the last three holes. I marked my ball placed it in my towel washed it and put it in my pocket. He missed his putt but was a tap it par so I prepared myself for my putt. As I put the ball down to line it up my heart stopped and about threw up right on the spot. It was NOT my ball! After a couple of very hard swallows I stopped what I was doing and called over my competitor and the official who was with our group and told them I played the wrong ball and would have to go back for a drop or look for my ball. (At that point it didn't matter if I found my original or not) and take a two shot penalty. I only had about another minute to look for my ball and no luck. Went back to the original spot dropped and finished the hole with a double bogey. Three shots down with three to go and I mentally lost it. All in all hitting the wrong ball cost me two places finishing third and with such a great team we managed to win state. I remember this shot/moment like it was yesterday and it happened over 12 years ago. I'm sure if you took me back to that course I could place my ball in the exact spot as i had to play from that day. That's my worst day and hope it wasn't too much to read.
