After three cashes in the 2009 World Series of Poker, Jetten started 2010 with a fifth-place result in the Aussie Millions Main Event to add another $300,000 to his bankroll. Later in the year, he returned to the WSOP and reached the final table of the $10,000 Pot Limit Hold ‘em Event, before making a deep run in the Main Event, where he finished in 54th place.
