ARDMORE, Pa. -- Tiger Woods wasn't feeling good about being 2 over par through 10 holes of the weather-suspended first round of the U.S. Open on Thursday.
A possible injury to his left wrist or arm could be making him feel worse.
It was unclear how serious the issue was Thursday night, as Woods only spoke briefly to a United States Golf Association media official and said it was fine.
But he clearly was bothered on several swings, most notably at the first and fifth holes, when he played shots to the green from Merion Golf Club's heavy rough. Perhaps not coincidentally, Woods made bogeys on both.
The No. 1-ranked player in the world bogeyed two of his first three holes and four overall, and faces a 4-footer for par at the 11th hole when play resumes Friday morning.
He is only six strokes back of on-course leader Luke Donald -- who got to 4 under par through 13 holes -- and five back of clubhouse leader Phil Mickelson, who shot 67. But Woods appeared a bit off and faces the toughest stretch of Merion's East Course when play resumes Friday morning.
"It's going to be a fast night," Woods -- who marked his ball on the 11th green as play was suspended at 8:16 p.m. ET, and noted that the PGA Tour has been plagued by weather issues throughout 2013 -- told the USGA official.
"It's kind of the way the tour has been this year. We've had a lot of bad weather this year, and this is the way it's been. I've got a lot of holes to play tomorrow. And hopefully I can play a little better than I did today."
Woods was not available to reporters but later said through his spokesman: "I'm doing fine and I'm looking forward to getting back out there tomorrow."
Woods, Rory McIlroy and Adam Scott were grouped together in what was supposed to be a marquee pairing, but they were upstaged by the weather and Mickelson. Due to morning thunderstorms and rain, their tee time was pushed back 3½ hours. They did not tee off until nearly 5 p.m. ET, and their round was interrupted by another weather delay before resuming.
That means a long day Friday in which Scott (3 under), McIlroy (even) and Woods will finish the 11th, then the remaining seven holes before beginning their second rounds.
What is unclear is whether Woods is injured. He was seen favoring his left wrist/arm several times, shaking it after shots, and appeared uncomfortable on one of his chip shots.
He three-putted the first hole, birdied the second, made another bogey at the third after a poor chip and then again hit a poor chip shot on the fifth. Woods rolled in a 50-footer for birdie at the sixth. He missed good birdie opportunities at both the eighth and 10th holes.
Woods has won four times this year on the PGA Tour but is going on five years without a major championship victory. His last came at the 2008 U.S. Open, giving him 14, four behind Jack Nicklaus.
