Masters champion Jordan Spieth made an early move up the leaderboard as the misery continued for former world number one Tiger Woods in the US Open today.
Spieth is looking to become just the sixth man in history after Craig Wood, Ben Hogan, Arnold Palmer, Jack Nicklaus and Woods himself to win the Masters and US Open in the same year.
The world number two can also became the first player since Gene Sarazen in 1922 to win multiple majors aged 21 or younger at Chambers Bay and was just two off the lead when he began his second round with a birdie from seven feet on the 10th, his opening hole.
Spieth looked certain to get even closer to overnight leaders Henrik Stenson and Dustin Johnson when he drove the green on the par-four 12th, only to three-putt for par after missing from two feet.
That was less of a surprise than usual given the state of the much-criticised greens, while Woods's approach to the 10th was equally no longer a shock.
From the middle of the fairway the 14-time major winner pulled his second shot onto such a steep slope that he lost his balance attempting to take his stance, with the resulting bogey dropping him to 11 over par and 154th in the 156-strong field.
Woods had struggled to an opening 80 on Thursday, his worst ever score in the US Open and his third round in the 80s in his last six events.
Spieth made amends for that missed opportunity by holing from 15 feet for a birdie on the 14th to move within what was now a three-way tie for the lead.
That was because 22-year-old amateur Brian Campbell, who had carded an opening 67 late on Thursday, had birdied the second and third to move to five under par.
Campbell, who missed the cut by a shot on his debut at Pinehurst last year, was one of the few players not unhappy with the state of the greens, saying after his first round: "I just felt comfortable on the greens. And the less you worry about it, the more comfortable you can be in just letting the putter go."
