What happened on day two of the US Open?

World No.1 Dustin Johnson surged to a four-shot lead courtesy of a fine Friday morning 67 at Shinnecock Hills.

The American began the day tied with Russell Henley, Ian Poulter and Scott Piercy, but he soon opened up a lead when going out in a bogey-free 33.

A bogey at his 10th hole halted progress slightly, but a further two birdies coming in allowed him to set the clubhouse target.

The round of the day belonged to England’s Tommy Fleetwood, though. The 27-year-old, who finished 4th at last year’s US Open at Erin Hills, made six birdies on the day to power through the field with a 66.

“Today felt like I played really solid,” Fleetwood said.

“At one point, it was the middle of the round, it was just keep going and try and survive whilst the rain is there and the wind picked up. Luckily enough, I caught a few birdies at the end, and 66 was very, very good.”

Late on Friday afternoon, it seemed as if Ian Poulter was going to be Johnson’s closest competitor. The Englishman was playing beautifully and got within one shot of Johnson – that was until he reached the penultimate hole of the day. Standing in the middle of the fairway, Poulter fanned his approach into the greenside bunker, thinned his bunker shot over the green, chipped into the thick rough, and eventually made a triple-bogey – undoing all of his previous good work. He’d then go on to bogey the last to fall five shots adrift.

Instead, Johnson’s nearest pursuers are Charley Hoffman and Scott Piercy, who are both locked at level-par.

Lurking just behind are a bunch of class-acts and major winners. Justin Rose, Henrik Stenson and Brooks Koepka are all five shots behind, while Rickie Fowler posted a 69 to trail by six shots.

Former champions Tiger Woods, Rory McIlroy, Jordan Spieth and Martin Kaymer all missed the cut, as did Jon Rahm, Sergio Garcia and Jason Day.

Yet Matt Parziale – the amateur who works as a fire-fighter – made the weekend after rolling in a 20-footer for birdie on his final hole. He’ll have to book a few more days off work.

It was also nice to see Scott Gregory sign for a 75 on Friday – 17 shots better than his opening round of 92.

Talking point

Dustin Johnson may seem like he hasn’t a care in the world. He doesn’t get too excited and doesn’t throw clubs when he hits a bad shot.

But that doesn’t mean he’s not a perfectionist who is constantly tweaking his equipment to get dialled in for each event he plays. Equipment Editor James Savage takes a closer look

The changing of the guard may have happened a while ago, but despite a fifth cut in his last seven major starts confirmed, Tiger Woods is still convinced he can win another. Alex Perry explained
