Jim,
If you keep the names for the three spots as.........

"Diamond, Platinum and Gold"

Then I can tell you now that whoever wins the GOLD could very easily say just that & nothing else & 100% of the people hearing that will think they WON! ONLY if they know that there is a Diamond & Platinum award will they ever know that Gold is third place. I can see it now.......A Casino wins the Gold & they say JUST that & anyone reading that assumes they WON the contest..............Andy - Las Vegas
