The 18-year-old Canadian became the youngest-ever EPT winner by outlasting 410 players to win the German Open, also down as EPT Dortmund.
McDonald, who is not yet out of braces, is already a third of the way there.
Ironically Griffin was the youngest-ever WSOP bracelet winner when he took down his first World Series event at 22. That record was short-lived, to say the least.
The young guns on the poker tour have certainly been making headlines the last 12 months. During the summer Steve Billirakis became the new youngest WSOP winner when he won Event 1 at the 2007 WSOP. Billirakis was 21 years and 11 days old when he won. (WSOP entrants must be 21.)
Not to be outdone, Annette Obrestad became the youngest player to win a WSOPE event when she took down the Main Event a couple days before she turned 19.
McDonald also played at the WSOPE but his results weren't quite as good as Obrestad's - he was eliminated out of the money by 2006 WSOP Main Event winner Jamie Gold.
Since then McDonald has gained plenty of poker notoriety by coming in 14th at EPT Prague, winning the $1,000 PokerPro No-Limit Hold'em event at the Aussie Millions and coming in eighth during the heads-up championship at the Aussie Millions.
McDonald also plunked down a cool $100,000 to play in the high-stakes tournament. It was a bold move for McDonald to play with the likes of Howard Lederer, Erick Lindgren, Nikolaus Jedlicka, Phil Ivey, John Juanda and 19 more extremely talented rounders. Unfortunately it didn't pay off for McDonald, who was one of the first players eliminated, although he did outlast Gus Hansen and Tony G.
All is well now for the young Canadian, however. There is no doubt that he will be a terror on the poker circuit for years to come - and given his age that means a very, very long time.
