Should have bought a lottery ticket!

It was a company tournament, shotgun start, last hole of the round (#13). My round was up and down and I was ready for it to be over. The 13th is a 175 yd par 3 with a water hazard that runs along the right. I teed up a "water ball" and hit a soft 4-hybrid straight at the pin. I lost sight of the ball but my spotter said I was on the green. Once everyone had hit we all headed towards the green. Upon arrival my ball was nowhere to be found, until one of our party looked in the cup...
