Rickie Fowler holds first-round lead at Erin Hills

McIlroy joked earlier in the week that anyone who couldn't hit such wide fairways "might as well pack your bags and go home".

Lawmakers are returning to the Capitol and, they hope, to some semblance of normalcy a day after a rifle-wielding attacker opened fire on Republican lawmakers as they practiced for a charity baseball game. "I can tell you nobody at this table got caught up".

The top three players in the world have never missed the cut in the same major dating to when the world ranking began in 1986.

Na himself shot 68 and 44 players went on to break par on day one. That's more than any before in the first round of a US Open. The previous record was 39 at Medinah in 1990.

Rickie Fowler may be leading the U.S. Open after carding a seven-under 65 in the first round at Erin Hills, Wisconsin, but a massive group of golfers is chasing the 28-year-old. Here's the first round leaderboard with prices to back at 11:20 United Kingdom and Ireland time.

"It rained the day before, and there was no wind, so the course was soft", he said. It doesn't appear that the draw is going to be pivotal and it doesn't look like today's morning starters are going to steal a march on those drawn in the afternoon so it's not something we need to get hung up on.

Dustin Johnson had to gouge it out of the rough on at least eight occasions, including the par-5 14th hole when he tried to play conservatively and laid up into rough. Three more players were just another shot back at 5-under. "I just didn't putt very good".

"It's going to be tough".

The Canadian finished second at the CareerBuilder Challenge thanks in part to a sensational 59 in the third round.

That group doesn't even include golfers such as Adam Scott, who registered an fantastic finish to land at even par, and 2015 U.S. Open champion Jordan Spieth, who didn't play his best golf but still managed to float above water at one over.

"It's cool, but it's just the first round", Fowler said afterwards.

The top six players in the world rankings all finished over par - a combined 21 over, in fact.

Casey has 13 European Tour wins to his name and only one on the PGA Tour but since settling in Arizona he has cut an assured figure in the USA.

McIlroy, just recently back from an injury, looked rusty and when you're not at your best at the US Open, it usually ends in a bad way for you, just like it did for the Irishman in this first round. The problem however was that it only lasted two holes.

Rory McIlroy made the fast start he was looking for at the US Open on Thursday but ended up trundling over the finish line after a back nine collapse.

One shot off of Fowler's lead is Xander Schauffele and Paul Casey, two shots back sit Brooks Koepka, Brian Harman, and Tommy Fleetwood. I'll just go out tomorrow and hit the fairways. It's not going to last. I paid the price for that. His transformation into one of the most mentally strong players in golf has been remarkable as well.

"I'd like to think if someone else is making birdies, it means they're out there", Casey said.
