Rory McIlroy digs deep in Players Championship as in-form Dustin Johnson looks to cement world number one spot
World number one Dustin Johnson sent a clear message to the posse of players queuing up to dethrone him when he opened with a blemish-free 66 in The Players at TPC Sawgrass.
Justin Thomas, Jason Day, Jon Rahm, Jordan Spieth and Justin Rose could potentially take over as world number one with a win but Johnson showed them all a clear pair of heels.
While Rose and Rahm shot 68s and Day a 69, Thomas struggled to a 73 and Spieth a 75. Rory McIlroy had to work hard for a 71 that was just a shot inside the projected cut line.
When the dust settled, Johnson was sitting pretty in a six-way tie for the lead with former US Open champion Webb Simpson, Sweden's Alex Noren, Chesson Hadley, Matt Kuchar and Patrick Cantlay, one clear of a six-strong group that included defending champion Si Woo Kim.
Johnson changed to the AimPoint green-reading method after a disappointing putting week at the Masters and got his reward for missing just one green in regulation, making four of his six birdies with putts between 10 and 34 feet.
"I felt like it was a really solid round," said Johnson, who started at the 10th and went out in five-under 31 before picking up his sixth birdie at the par-five second.
"I drove it very well and hit a lot of greens. I wasn't too sharp with the irons but I was still on the green and rolled the ball pretty well. I felt like all the putts I had to today I had the right reads on, which is something I haven't been doing very well."
As for his world No 1 ranking, he's clearly keen to hold on to it for a 65th consecutive week.
"I definitely want to stay there," Johnson said. "If someone plays well and passes me, obviously they deserve it. But I'm going to do whatever I can to stay there."
The stellar threeball of Tiger Woods, Phil Mickelson and Rickie Fowler failed to sparkle - the left-hander shooting a ragged 79 to Woods' erratic 72 as Fowler signed for a 74.
Unlike Spieth, who started bogey-bogey-eagle-double bogey and found water three times in his first seven holes en route to a disquieting 75, McIlroy got off to a good start.
Starting on the back nine, he birdied the 11th from 20 feet and two-putted the driveable 12th before following a three-putt bogey at the 13th with an easy birdie four at the 16th.
The Co Down man is trying hard to be disciplined on a tactical track that he's trying hard to love.
But he couldn't resist his attacking instincts at the 18th and pulled a driver into the lake before getting up and down from 110 yards for a bogey five, making a 12 footer.
After taking four to get down from greenside rough at the par-five second, slipping back to level par with a six there, he chipped in for birdie at the fourth but had to work hard to par his way home for his 71.
Like McIlroy, Shane Lowry started on the back nine and picked up early birdies at the 12th and 13th before he double-bogeyed the 14th and 17th after tee shots found water.
Turning for home, the Offaly man made a 32 footer for birdie at the par-five second, but he bogeyed the seventh and then drove into the lake at the par-five ninth, finishing with a bogey for a 75.
In the European Tour's Rocco Forte Sicilian Open, Derry's Ruaidhri McGee is 12 strokes behind Denmark's Lucas Bjerregaard and England's Ryan Evans after a six over 77.
On the Challenge Tour, Ardglass' Cormac Sharvin is just three shots behind Spain's Adri Arnaus, tied for second after a three-under 69 in the Open de Portugal at Morgado Golf and Country Club.
Ballymena's Dermot McElroy is tied fifth after a 70 with Moyola Park's Chris Selfridge and Naas' Jack Hume just inside the cut mark after 73s.
Jonny Caldwell and Stuart Grehan signed for 75s and Conor O'Rourke posted a 76.
