American JB Holmes tied the tournament record with a sizzling 10-under 62 to surge into a four-shot lead over a world-class field in the opening round of the WGC-Cadillac Championship on Thursday.
The 32-year-old from Kentucky tamed Doral`s Blue Monster course by hitting 15 of 18 greens as he goes for his first title of the season.
"You get a lot of adrenaline and everything going in a round like this," Holmes said. "I am pretty sure it is pretty good right now."
Holmes, who shared second place at the Farmers Insurance Open in early February, started on the back nine.
He got off to a flying start with two birdies followed by an eagle on the par-five 12th.
He two-putted for a birdie on the 10th then drained a 35-foot birdie putt on the 11th. His approach at 12 landed a foot away from the cup for an eagle.
"We had a game plan," Holmes said. "I hit all my shots where I needed to.
"I made sure I tried to stay below the hole. I had a day where I made a lot of putts. I hit great shots. My tee ball was right where I wanted it to be and I just didn`t have that many bad swings.
"I had a couple of bad swings with the driver," he added, "but I made birdie on those two holes."
Holmes`s 62 matched the tournament record on the redesigned Blue Monster set by Bubba Watson in the second round in 2012.
Stephen Ames fired a 61 on the old layout in 2000.
Fellow American Ryan Moore was alone in second place after firing a six-under 66. Moore was tied for the lead with Holmes late in the round, but he found water off the tee at the 18th and that led to a closing double-bogey.
Until then he was nearly flawless, with five birdies in his first nine holes, followed by three birdies at 10, 11 and 12.
His drive at 18 bounced in the fairway but hit the water and he was in a bunker with his third shot.
"I controlled my ball beautifully today and putted great on top of that," he said. "I made a lot of 10- to 15-footers. Honestly, I haven`t done that a lot lately and that`s probably the best round of golf I`ve played in a little while," said Moore.
Rickie Fowler, former runner-up Dustin Johnson and France`s Alexander Levy share third place at four-under. Henrik Stenson of Sweden and Brooks Koepka of the US were a further stroke back at three-under 69.
Former Masters champion Adam Scott, who is making his first PGA Tour start of the season, carded a two-under 70. The Australian was joined in eighth place by Jim Furyk, Charley Hoffman, Gary Woodland and Jamie Donaldson, who shared second place last year.
World number one Rory McIlroy bounced back from a tough opening nine holes to post a one-over 73. He is tied for 27th with 11 others, including Keegan Bradley, Matt Kuchar, Justin Rose, Sergio Garcia and Graeme McDowell.
