Kaymer took control of this event during round two and from there on the outcome was hardly ever in doubt. He led by three at the halfway mark, by five after 54 holes and a near faultless final round of 66 saw him blitz a field which contained four of the leading five players in world golf.
The victory will take Kaymer past Tiger Woods and into the number two position in the game and has him hot on the heels of current number one Lee Westwood.
Rory McIlroy's strong finish to round three and a solid final round of 69 moved him through the field to grab second place ahead of Graeme McDowell and Retief Goosen, the latter of whom produced the best round of day four when he recorded a 64.
It was Kaymer's first tournament of 2011 and while 2010 will be hard for him to replicate or better he has certainly started in the right fashion.
Scott Strange headed the Australians when 11th, recording his best European Tour finish in more than twelve months in the process.
Richard Green was 31st, Brett Rumford 46th and Danny Lee 53rd.
