Rory McIlroy lasted only two rounds in his first tournament of the year, but his return to action this week could be even shorter.
The world number one, who was out of sorts with his new Nike clubs in Abu Dhabi last month, has chosen the WGC-Accenture Match Play Championship in Tucson for his second appearance.
Shane Lowry, a team-mate of McIlroy when Ireland won the European amateur title six years ago and stablemate now, is his opponent in Wednesday's opening round at Dove Mountain.
Sixty-seven places separate them on the world rankings but McIlroy, runner-up to Hunter Mahan last year, needs to be on his guard on a day that also sees a clash between the two other Irish golfers in the field – Graeme McDowell and Padraig Harrington.
Twelve months ago, top seed Luke Donald lost to bottom seed Ernie Els, the same happened to Steve Stricker against Ross McGowan three years ago and, in between, Lee Westwood was knocked out in the second round by Nick Watney.
Lowry, winner of the 2009 Irish Open when still an amateur, was in line to face Tiger Woods until Swede Fredrik Jacobson, in the field as the replacement for injured Brandt Snedeker, finished joint third at the Northern Trust Open in Los Angeles.
"I suppose I would rather (play) Rory," Lowry said before knowing which of the two superstars it would be.
"I would be intimidated if I played Tiger. Since I started golf it's always been Tiger who's been the greatest. Standing on that first tee against him would be nerve-racking.
"I'd enjoy playing Rory and there probably is a bit of pressure on him, what with the change of clubs and having not played for a month since missing the cut at Abu Dhabi."
But Lowry added: "Rory is Rory – he's still the best in the world.
"It's funny, we've never played against each other before, despite coming through the amateur ranks together.
"The way I look at it is that, whoever I play, I'll have nothing to lose and everything to gain. This is going to be a great experience and a great chance to prove myself against the best.
"If I play my best golf I'll have a really good chance of beating whoever I'm up against. I'll tell myself that I came up against the best in the Irish Open (McIlroy was in the field) and a nobody – and I managed to win that."
Meanwhile, Welshman Dave Thomas, twice runner-up in the Open Championship and a renowned course designer, has been awarded honorary life membership of the European Tour.
Now 78, the Newcastle-born Thomas tied with Australian Peter Thomson at Royal Lytham in 1958 before losing in a 36-hole play-off and eight years later at Muirfield was joint second behind Jack Nicklaus.
He played in four Ryder Cups between 1959 and 1967 and represented Wales 11 times in the World Cup of Golf before arthritis ended his playing career.
Co-designer of The Belfry with Peter Alliss, Thomas was also captain of the Professional Golfers Association during its centenary year in 2001 and five years later was made an honorary life member of the PGA.
European Tour executive director George O'Grady said: "It has been remiss of us not to have presented this award a long time ago, but today we are righting that wrong.
"We have recently honoured Tommy Horton, Brian Huggett and Peter Alliss and Dave is in that league in helping build the game in Britain and all over the world."
Thomas said: "I have very fond memories of my playing career, but by 1969 my back had gone and it was time to do something else and what do you do?
"Someone suggested some design and architecture.
"Peter Alliss was involved and we became designers. Who would have thought all these years on I would be close to designing 150 courses?"
