Westwood has been a model of consistency this season, winning just the once but being in contention in nearly every event he has played. He is arguably the best player in the game without a major to his name although Steve Stricker and Paul Casey could also lay claim to that title. Westwood's fine tournaments at the Open Championship and the US PGA Championship, where he finished third on both occasions, probably give him the nod in that regard.
Westwood's victory moves him to number four in the world and given that he started the year in 10th position this has been a breakthrough season for him.
The 36-year-old's final round of 64 left many of the game's finest players in his wake, stretching a two shot lead 54 hole lead to six over second placed Ross McGowan with Rory McIlroy third and Padraig Harrington and Geoff Ogilvy in a share of 4th.
Westwood secured not only the Ã¢Â‚Â¬830,000 first prize but he also finished atop the Race to Dubai standings for the season, Ã¢Â‚Â¬620,000 ahead of McIlroy.
Westwood was obviously happy with what he had achieved.
"I'm delighted to be stood here and it's got to be the best day of my golfing career. I think that's about as good as I've ever played under this pressure."
Ogilvy was the leading Australian in a share of 4th, Adam Scott continued his recent progress to finish 7th, Robert Allenby was 13th and Scott Strange 23rd.
Ogilvy also led the Australians in Europe this season finishing 6th on the overall Race to Dubai money list.
