Who named the Arizona Diamondbacks?

The owner, Jerry Colangelo, held a name-the-team contest by taking out a full-page ad in the sports section of the Arizona Republic on February 13, 1995. The winner would receive a pair of lifetime season tickets. Eventually Diamondbacks was chose after the Western diamondback, a rattlesnake native to Arizona that's know to inject a large amount of venom when it strikes.
