ARDMORE, Pa. (AP) -- Tiger Woods quickly put two shots in the rough when he resumed his first round Friday morning at the U.S. Open.
The silver lining for the world's No. 1 player: at least his wrist looked fine.
Woods pulled out his driver and put his first tee shot of the day well right of the fairway into the high grass at Merion. On Thursday, he would wince and shake his left arm, particularly his wrist, when playing out of the rough, but there was no obvious sign of discomfort when he played his second shot at the long par-4 No. 12.
There wasn't much else good about the shot, which landed in lesser rough about 100 yards from the hole. Woods then got the ball on the green, but he missed a downhill 5-foot putt and bogeyed the hole to go to 3 over.
Woods birdied the short par-3 13th, but he still had work to do to get on the leaderboard. Luke Donald held the overnight night at 4 under through 13 holes when darkness stopped play Thursday.
The rain returned Friday morning, although it was gentler than the severe storms that interrupted play twice on Thursday. While Woods struggled, others took advantage of the wet conditions.
Donald birdied his last three holes Thursday, and Masters champion Adam Scott had birdied No. 11 to go to 3 under when play was done for the day. Donald remained at 4 under with a pair of pars through his first two holes Friday, but Scott dropped a shot at the 12th after his approach landed just short of the pin, spun backward and rolled some 75 feet to the edge of the fairway rough.
"Obviously the weather conditions are making the course a lot softer, and you can attack the pins a little bit more," Donald said after Thursday's play. "So it's playing as gentle as it might play so far, and obviously this afternoon not much wind. If you were going to make a score, today was a good day."
The clubhouse leader was Phil Mickelson, who shot a 3-under 67 after a different sort of physical challenge.
He had only a few hours of sleep after flying overnight from San Diego to watch his daughter's eighth-grade graduation, where she was one of the featured speakers. He said he hit the wall at the turn and needed a "caffeine booster" to keep him sharp.
"I'll just go back tonight and rest, and I'll have all day tomorrow to rest and it's fine," said Mickelson, who was scheduled for a late afternoon tee time Friday for his second round. "It shouldn't be a problem."
Woods first appeared to hurt his hand after trying to gouge out of the deep rough on the opening hole Thursday, then shook his wrist again after hitting a 5-wood out of the rough at No. 5.
No. 11 was been particularly difficult: He doubled over after hitting his second shot from the left rough, the ball landing in even thicker rough near the green. He dropped his arm to his side immediately after his next shot and was shaking the arm as he walked on the green.
Later, in a statement issued through his spokesman, Woods insisted that all was well.
"I'm doing fine," he said, "and I'm looking forward to getting back out there tomorrow."
An Open question was how Merion would fare against a modern-day championship field. It last hosted this event in 1981, with the thinking that today's golfers had outgrown the course.
Certainly, the 301-yard par-3 10th and 102-yard par-3 13th yielded their share of makeable shots - about 30 percent of the birdies on Thursday came on those two holes - but the high rough, obstructed sightlines and contoured greens did their share to keep the scores from getting too low.
"I always knew this golf course was going to throw birdies at you, and I always knew this golf course was going to throw some bogeys," said Ian Poulter, an appropriate analysis after his round of 71 included five birdies, four bogeys and a double bogey.
"And it's fun and in a kind of up and down way, because that's what it's going to be. No one is going to get around this golf course without making mistakes. You have to manage them really, really well."
Of the 78 players to complete the first round, only Mickelson and Belgium's Nicolas Colsaerts (69) were under par.
Sergio Garcia shot a 73, finding Merion far more daunting than a few wisecracks from the gallery. The Spaniard received mostly warm applause, with some barely audible boos from the grandstand, when he started his round on No. 11.
It was his first time competing in America since his public spat with Woods took a bad turn when he jokingly said he would have Woods over for dinner during the U.S. Open and serve fried chicken.
"There were a couple here and there," Garcia said about the hecklers. "But I felt the people were very nice for the whole day. I think that almost all of them were behind me and that was nice to see."
