Playing in our association event, walked to the 13th tee. Slight breeze into us from 188 yards, just needed a smooth swing to hit the green. Once in the air, the ball was on line, it hit the green and no one saw it from there. Someone said “I think it went in”.... not getting overly excited, we looked through the range finders. Nothing visible however didn’t want to get celebrate too early. As we approached the green, no sight of the ball until we looked in the hole. At that moment, I now know the ball went into the hole!
