Dyson birdied the first playoff hole last year to defeat Richard Green and claim his second title of the '06 season. So far in 2007, the only player to repeat as champion on the European Tour's International schedule has been World No. 1 Tiger Woods, who has repeated at three events.
Dyson is coming off a great final round at the PGA Championship, where he closed in 6-under 64 to finish as low European player.
Bernhard Langer hopes to return to action this week, alongside his son Stefan, at this event. The elder Langer has been out of action recently due to a hospital stay to remove kidney stones. Bernhard Langer is a three-time winner here.
This tournament is one of the oldest on continental Europe, dating back to 1912. Last year's playoff was just the fourth since 1972.
