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 on Friday.
pieth 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. He picked up a birdie on his third to remain at 10 over.
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.
