LA JOLLA: England's Richard Bland and American Russell Henley, an unlikely pair of major pace-setters, shared the lead after Friday's (Saturday in Manila) second round of the US Open with South African Louis Oosthuizen one stroke adrift.

Henley, on a four-year US Professional Golfers' Association (PGA) win drought and never a top-10 major finisher, lipped out a 2-foot par putt on his final hole to fire a one-under 70 and settle for a share of the 36-hole clubhouse lead on five-under-par 137.

'I feel good about my game,' Henley said. 'I've never been in this position before in a major. [I] just feel like I'm going to learn something no matter what happens.'

Bland won his first European Tour title at last month's British Masters after 478 starts over 25 years, becoming the tour's oldest first-time winner at age 48.

After shooting 67 on Friday, he's a threat to become the oldest winner in US Open history, breaking the mark of 45 set by American Hale Irwin at Medinah in 1990.

'I'm feeling pretty good,' Bland said. 'I've been driving the ball good for five or six weeks now, which is the cornerstone if you're going to put a fight up for a US Open.'

Oosthuizen, the 2010 British Open champion with five major runner-up efforts since winning at St. Andrews, fired 71 to share third on 138.

'[I] drove it nicely,' he said. '[I] felt like I'm putting nicely, and [I] kept it all together.'

Alongside Oosthuizen was 22-year-old American Matthew Wolff, last year's US Open runner-up, who is coming off a two-month mental health hiatus.

'Even today, after playing well yesterday, I was still [feeling] like I wanted to stay in bed. I wanted to be where I was comfortable, not in the spotlight,' Wolff said. 'It's awesome that I came out here and played well, but I think more importantly, I'm just getting closer to being more comfortable and being happy and enjoying it.'

Two-time Masters champion Bubba Watson and third-ranked Jon Rahm of Spain shared fifth on 139.

World number 63 Henley started on the 10th hole, sank a 6-foot birdie putt at the 18th, rolled in a clutch par putt from 17 feet at the sixth and dropped a birdie putt from just inside 7 feet at the par-3 eighth to seize the lead.

But after missing a 17-foot birdie putt at the par-five ninth, his tap-in miss left him level with near-total-stranger Bland.

'I'm sure he knows nothing about me too,' Henley said.
