The Triple Crown of Poker consists of winning a poker title in the three major poker tours/events: The World Series of Poker, World Poker Tour and European Poker Tour.
So far, only five players have completed the feat: Gavin Griffin, Roland De Wolfe, Jake Cody, Bertrand Grospellier and Davidi Kitai. In 2008, Griffin won his first World Poker Tour title, becoming the first to complete the feat.
On January 25, 2010, Cody won the EPT Deauville. He followed that up on September 4, 2010, Cody won the WPT London Poker Classic, and then, he completed the feat on June 4, 2011. It took him 1 year, 4 months, 11 days, which is the quickest of the five and the only one that did it in less than three years.
