Bernd Wiesberger is the clear 4/1 favourite to warm up for next week’s US Open with a second victory in the Lyoness Open.
Wiesberger triumphed at Diamond Country Club in 2012 and will be well backed to claim a second European Tour title of the season following his play-off win over Tommy Fleetwood in the Shenzhen International in April.
The vagaries of the world rankings mean that 2015 winner Chris Wood has withdrawn from the event to improve his chances of remaining 60th in the world and therefore qualifying for the US Open.
That leaves Wiesberger and Joost Luiten (12/1) as the only players in the world's top 100 in the field, with defending champion Wu Ashun (100/1) having dropped to 272nd after seven missed cuts in 11 events this season.
“It's a big thing for me and Austrian golf,” world number 29 Wiesberger said of the 1million euro event. “I think every Austrian is looking forward to it and preparing the way to perform their best this week, and it is the same for me. I am hoping to bring my A game.
“I had the chance to play a couple of holes last Thursday to give myself a little bit more freedom going into this week and not play too many holes, and I think it's going to play similar to what it has in previous years.
“A lot of rough and the fairways and greens are meant to be quite bouncy and firm, so if you are driving the ball well I think the course gives you lots of opportunities and that is something I will try and do this week.”
Luiten has finished third, first, third and sixth in his last four appearances in Austria and last week's missed cut in the Nordea Masters was his first since last year's Dunhill Links Championship.
He is 12/5 for a top-five finish and said: “I like this course so hopefully it will give me some confidence and give me that feeling back of the other years when I have been playing here, and I can take that into the week.”
