Rory McIlroy made a solid start in his bid to complete a full set of World Golf Championship titles as Matt Fitzpatrick and Webb Simpson claimed a share of the clubhouse lead in the WGC-Workday Championship.

McIlroy carded an opening 69 which means he will start Friday's second round three shots off the lead, while Shane Lowry is six adrift of the summit.


McIlroy made a strong start at the Concession Golf Club in Florida, with a birdie on his first hole at the 10th, before finishing his opening nine holes with two further birdies on the 13th and 16th.

The rest of the World No 8's round was more of a mixed bag with three further birdies but three bogeys as he finished up on three under after an opening 69.

Victory on Sunday would make the Holywood, Co Down native the second player after Dustin Johnson to have won all four WGC titles and see him continue his impressive record of bouncing back from missed cuts.

His missed cut in the Genesis Invitational last week was his first since an emotional early exit from the 2019 Open Championship on home soil at Royal Portrush, but the 31-year-old's record after his five most recent missed cuts includes two wins and a runners-up finish.

After starting from the 10th, McIlroy found himself four under par after 12 holes, but missed short par putts on the fourth and fifth and another from six feet for birdie on the eighth.

"I missed three putts on the last nine holes that I thought for sure were going to go right to left, and then I missed one on another hole that I gave a little less break as a reaction to those and that one dove and broke left," McIlroy told Sky Sports.

"I felt like I got a good feeling with what I'm doing with the long game so I'll hit a few balls to try to groove that in and I'll go to the putting green to try to figure it out a bit.

"Of course it's frustrating because you come off the course thinking you could be three or four shots lower than you were, but I've just got to keep putting the work in and hopefully it finds its way in there.

"I holed some good putts out there, it's not that I didn't hole anything, it's just that I missed a few."

Meanwhile, Lowry made a slower start with a bogey on the 10th but returned to level par with a birdie on the 17th. A similar pattern ensued on the front nine with a birdie on three cancelled out by a bogey on the ninth.

The Offaly native will start Friday's second round from level par.

Former world number one Brooks Koepka is a shot off the six-under lead held by Fitzpatrick and Simpson in a four-way tie with Billy Horschel, Kevin Kisner and Sergio Garcia.

Koepka's 67 was 10 shots better than playing partner, Masters champion and current number one Johnson, who carded two birdies, two bogeys and two double bogeys.

World number seven Patrick Cantlay withdrew before the start of play due to illness.

"Unfortunately, due to an upset stomach and dehydration, I have withdrawn from the WGC-Workday Championship at The Concession," Cantlay said. "I'm extremely disappointed, but looking forward to getting back out on the course soon."
