More woe for Woods
It couldn't get much worse for Tiger Woods after his ten-over-par first round on Thursday, and it did improve, albeit marginally as the 14-time major champion struggled once more to a six-over-par 76.
Once again, Woods started his round with a bogey - this time on the tenth - and he bowed out of the tournament with further dropped shots at the seventh, eighth and ninth.
"I wanted to shoot five or six today, but I wanted to be on the other side of it," said the 39-year-old. "I hit it a little bit better today. But, again, I made nothing.
"On a golf course like this you get exposed and you have to be precise and dialled in. I didn't have that and obviously I need to get a little better for the British Open and I'll keep working at it."
The former world No.1 now looks set to drop out of the world top 200 after posting the worst 36-hole score of his professional career, with only Darren Clarke, Cole Hammer and Alex Kim below him on the leaderboard.
New leading pair
It was Dustin Johnson and Henrik Stenson who held the lead after round one, and heading into the weekend it was two more big names who had assumed the top spot on the leaderboard on five-under-par.
Masters champion Jordan Spieth followed up his round of 68 on Thursday with a three-under-par 67 to post the clubhouse lead from the morning starters, while Patrick Reed - who battled it out against Spieth in a play-off at the Valspar Championship earlier this year - followed up his opening round 66 with a 69, although he was as low as seven-under-par after an eagle at the par-4 12th.
Speaking after his round, Spieth took a pop at the 18th hole, which was playing as a par-4 yesterday. He said: "I think 18 as a par-4 doesn't make much sense. Of course at the moment when I didn't hit the right shots it's going to make less sense. I thought it was a dumb hole today, but I think we're going to play it from there again, so I've got to get over that."
Concern for Day
There was great concern on the ninth fairway as Jason Day, Spieth and Justin Rose were about to conclude their rounds as the Aussie collapsed, requiring urgent medical attention.
Remarkably, Day was able to complete his round, playing a superb bunker shot considering the circumstances before tapping in for bogey to finish on two-under-par.
Afterwards, the Aussie's agent revealed that he had been suffering from benign positional vertigo, but is hopeful that he can take his place in the field for the final two rounds.
Nightmare end for Westwood
After the 17th at Chambers Bay yesterday, Lee Westwood was four-under for the day and into red numbers after surging up the leaderboard following a 73 on Thursday.
But at the last, it all went pear-shaped for the Englishman - who after dropping just two shots earlier in his round - recorded a triple-bogey to drop back to two-over-par for the tournament.
Afterwards, Westwood tweeted: "Played great today. Shame about 18. I know I made triple but it's a stupid par-4 and a great par-5."
Day of struggle for Scots
Well-placed after day one, both Marc Warren and Colin Montgomerie dropped down the leaderboard on Friday afternoon after rounds of 74 and 76 respectively.
Warren started with back-to-back bogeys to drop back to level par, and it was his poor showing on the two par-5s on the back nine which produced two more bogeys.
Montgomerie was in danger of missing the cut after an impressive 69 on Thursday, but thankfully, Nick Hardy's bogey at the last saw the cut drop to five-over-par to hand the 51-year-old and the likes of Ian Poulter and Jimmy Walker the chance to play at the weekend.
It was slightly better for Stephen Gallacher (72), Bradley Neil (73) and Jimmy Gunn (73), but none of the trio made the cut.
