Tiger Woods struggled on the practice range, and he didn’t feel much better two holes into his second round Friday at the Cadillac Championship in Doral, Fla. He would not have guessed this would be the day to set a personal record for birdies, much less wind up with a two-shot lead.
‘‘All I need is one shot,’’ he said. ‘‘And as soon as I feel it on one, I can pretty much carry through. And I did that today.’’
It was a 4-iron on the par-3 fourth hole, the toughest on the Blue Monster.
Woods hit a bullet with a slight fade at the left edge of the green and heard the crowd cheer as the slope and the grain took the ball to within 4 feet for birdie.
And just like that, he was on his way.
In a World Golf Championship with the biggest names in the hunt, Woods ran off six birdies in an eight-hole stretch around the turn in a clean, crisp exhibition. That sent him to a 7-under-par 65 and a two-shot lead over former US Open champion Graeme McDowell.
Woods has made 17 birdies in two rounds, his most on the PGA Tour, though that wasn’t the most important number.
‘‘It left me a two-shot lead,’’ Woods said.
He was at 13-under 131, his lowest 36-hole score on tour since the 2009 AT&T National.
On No. 5, Woods had a wedge he stuffed to inside 2 feet. He added a collection of 10-15-foot birdie putts, and ended his big run with another 4-iron with a totally different shape, this one high and soft to 15 feet on the 224-yard 13th hole. Those par 3s ranked as the two toughest at Doral on Friday, and he birdied them both.
A birdie-birdie finish by McDowell gave him a 67 and prevented a dream final group for the weekend at Doral — Woods and longtime nemesis Phil Mickelson.
Mickelson, sparked by a visit to Augusta National earlier in the week, hit a 9-iron that stopped inches from dropping for a hole-in-one on the par-3 ninth. He had a 67 and was three shots behind, along with Steve Stricker (67).
Rory McIlroy showed signs of turning the corner with a 69, although he ended with a sloppy three-putt bogey. It was his first round under par this year, a small consolation for the world’s No. 1 player. He was still 11 shots behind Woods.
PGA — Andres Romero shot his second straight 7-under 65 to take a one-stroke lead in the Puerto Rico Open in Rio Grande.
Romero had a double bogey on the par-3 eighth hole, then birdied six of the last 10 holes. Returning to a center-shafted putter, he has made 16 birdies and an eagle in 36 holes.
Scott Brown was second after a 63. Steve LeBrun and 2010 US Amateur champion Peter Uihlein of Mattapoisett, Mass., shot 65 to reach 12 under.
Uihlein is in position to earn a spot next week in the Tampa Bay Championship with a top-10 finish. The former Oklahoma State star is coming off a fourth-place finish last week in South Africa.
Fabian Gomez was 11 under after a 64. Defending champion George McNeill, Jon Curran of Hopkinton, Mass., and former Masters champ Angel Cabrera were in a group of nine players at 9 under.
