Rory McIlroy's bad start to 2013 continued as the world number one lost out in the opening round of the WGC Match Play in Arizona.

McIlroy lost on the final green to fellow Irishman Shane Lowry to become the third top seed in the last four years to exit in the first round.
Tiger Woods and Lee Westwood were also knocked out on Thursday.
Woods lost 2&1 to Charles Howell III, while Westwood was beaten by Rafael Cabrera Bello of Spain.

McIlroy who changed ball and club sponsors at the start of this year in money spinning deal has struggled for form since, missing the cut in his opening event of the year in Abu Dhabi last month.
And McIlroy knows he has plenty of work to do after his defeat to a player ranked 68 in the world who secured victory with a dramatic final three-foot putt.

"I drove really well, but couldn't take advantage of that," McIlroy said. "If I'd hit my irons better it could have been a different story.

"I could have been three or four up early on, but let him get back into the match and he had a nice little run."
