Former World No.1 Tiger Woods was left to rue a frustrating finish to his opening round at the US Open as he failed to take advantage of perfect conditions at the notoriously tough Winged Foot course.
Woods recovered from two over par after five holes with the aid of a hat-trick of birdies around the turn, only to bogey the 17th and run up a double bogey on the last after duffing a pitch from short of the green.
The resulting 73 left the Masters champion eight shots behind playing partner and clubhouse leader Justin Thomas, who enjoyed a one-shot lead over Ryder Cup team-mate Patrick Reed.
"I tried to stay as patient as possible, and unfortunately just did not finish off my round the way I needed to." - Tiger Woods.
Rory McIlroy carded a three-under-par 67 as seven early starters broke the par of 70.
In contrast, Colin Montgomerie's 69 was the only sub-par score in the opening round at Winged Foot in 2006 which was eventually won by Australia's Geoff Ogilvy with a five over par score.
"Well, it was a bit of ebb and flow to the round today," Woods said.
"I made a bunch of putts in the middle part of the round.
"It seemed like most of my drives on the front nine landed in the fairway and ended up in bad spots, and I tried to stay as patient as possible, and unfortunately just did not finish off my round the way I needed to.
"I thought the golf course was set up fantastic.
"I thought that what they did with the hole locations were very fair today. It gave us an opportunity to make some birdies, and you look at most of the scores, and the guys took advantage of it.
"I don't see any reason why it won't get harder and get more difficult. I just think that the golf course is there to be had. They gave us a lot of opportunities with the hole locations."
