Irish warriors Darren Clarke and Gary Murphy have the guts and determination to come through two massive tests this week.

At least, that’s the view of managers Chubby Chandler and Gary Evans who will be watching the scoreboard nervously as their men launch last gasp bids to salvage their season in Hong Kong and Melbourne.

Clarke needs at least a top-20 finish in the UBS Hong Kong Open to make Europe’s top 60 and join stablemates Lee Westwood and Rory McIlroy in next week’s $7.5m (€5m euro) Dubai World Championship.

But it’s an even bigger task for Kilkenny cat Murphy, who rubs shoulders with world No 1 Tiger Woods in the clashing JBWere Australian Masters needing at least a top-15 finish to avoid a trip to the qualifying school.

Chandler, who also manages Race to Dubai rivals McIlroy and Westwood, said: "Darren wants a chance to win the biggest prize on the European Tour and he is fighting to the bitter end to earn that opportunity.

"He’s so keen to be among the Dubai line-up that he travelled to Hong Kong last week to begin his preparations and I think his efforts will be rewarded.

"This is Darren’s last chance but I’m pretty confident he’ll take it. This is what the Race to Dubai has done. It has made players focus sharply on the end of the season."

Clarke is 63rd in the money list and nearly €20,000 outside the top 60 who will get to tee it up at the Earth course in Dubai next week.

But Murphy’s position is even more critical after a nightmare season that has seen him lose sponsors and struggle with personal issues off the course.

Ranked 127th in the Race to Dubai, he’s almost €14,000 outside the top 119 who will finally keep their cards.

That means he must finish at least 15th in Australia this week and he’s determined to end a nightmare year with a top performance a classic Kingston Heath lay-out.

Former tour player Gary Evans, who manages Murphy through the Dublin-based Green 17 agency, said: "You can look at Gary as a guy who has been struggling, but the real story is that he’s a guy who has refused to go down when others would have thrown in the towel a long time ago."

Evans persuaded Murphy to part with his swing coach David Downie in August and seek help from "personal development" guru Andy Duncan, who works on the mental side of the game with Ryder Cup star Paul McGinley.

Evans said: "It has worked wonders and over the last three months Gary has got himself within a cat’s whisker of keeping his card.

"We got him into Singapore at the last minute two weeks ago and he was really unlucky to miss the cut there. 

"But even if he has to go to tour school, I am 100 percent confident that over six rounds he will retain his card no problem.

"He has two more chances as I see it and he is in a good place mentally after a very tough year.

"We had a couple of sponsors for Gary and they disappeared because of the financial crisis and that adds pressure. 

"All these factors come together in a golfer’s mind and Andy just pointed out to Gary that he can’t control these things and all he can do is go out and control his golf."

All eyes will be on the clash between Westwood and McIlroy in Hong Kong with the English veteran just €50,000 ahead of the Holywood star at the top of the Race to Dubai rankings.

Beaten in a play-off in Hong Kong last year, McIlroy said: "Experiences on the course make you learn about your game and yourself.

"A year on, I feel every day I wake up is a day to learn something new. I feel I need to keep doing that. I am still the same person as last year but my results have been better this year.

"Winning this event will take care of catching Lee so that's what I am focusing on. I will be keeping an eye on Lee's scores all week. 

"There is not much between us now so any ground I can gain this week will be good to take into Dubai but winning will take care of that gap so that is my main focus."
