Hit a solid tee shot and watched the ball flight. Noticed it landed in the middle of the green but couldn't see it go in as the green is two-tiered and from the tee box you can see it go in. However the members of my group were positioned to where they could see the ball roll into the cup. They said, "I think that went in...". When we got to the green we noticed my ball sitting in the cup! It was at that time we started celebrating.
