The pilot of a small blimp that crashed Thursday near the U.S. Open in Wisconsin during the opening round of the golf tournament suffered serious injuries, including burns, investigators said.

Hurdzan and Fry, who worked together on projects as well as designing their own courses, were among six finalists for the job of designing Erin Hills. And it's a bit of a mystery to those players from around the world who will tee it up beginning Thursday.

"Really?" McIlroy said during his news conference.

"Dad played rugby for Wasps in the seventies and they are both PE teachers and are very sporty and know what I'm striving for. I'm sure I'll be just fine".

Enjoying it to a point. Avoid the thick, knee-high fescue at all costs.

"All I was trying to show was the fans was an inside-the-ropes view of what we're dealing with", Na said. "It is brutal. It is so hard". It will be longer, and it will probably have a higher missed fairway penalty given how badly you have to hit a shot here to actually miss a fairway.

"If you put red lines just right along that people wouldn't complain, it's a hazard".

But Harvey gets it. The crash happened east of the grounds, in an open field.

Ernie Els, the only South African US Open victor in the field (1994 and 1997), has been showing signs of getting back into form.

On how far he has come in a short space of time, Wallace said: "It's come fast but at the end of the day it's just golf". "Then you've got about 3 or 4 yards of normal rough, which is fine. When you get to the fescue, you really are anxious about whether you can hit your ball at all".

A man for the big occasion, the 25-year-old has done well at the Majors before, but he hasn't set the scene alight since winning the RBC Heritage a year ago.

"It was definitely hectic getting out here", Harvey says.

"I'll be really glad that I was there and present". "It's a long golf course, and it's only going to play longer". He's just too good of a player.

"Oosthuizen has fared well at the US Open in his previous appearances, tying for second with Dustin Johnston in 2015, and his proven mental fortitude will pay dividends at an unfamiliar course where many lack experience". But he finished in the top 13 in three of the four tournaments he's entered since.

"It's been very fun the last couple of days". "It's like a links golf course on steroids, everything is a little bigger", Rahm said. It's more made up of glacial till. "There's no need to injure my wrist this week before I tee off". You can do the math.

"I changed that when I was 20 when I had this thought of: "What am I going to do when I'm 30?"

The now famed fescue grass has had a rough time of it from some of the players this week - U.S. golfer Kevin Na's Instagram video vividly revealed the difficultly of finding a ball, let alone trying to hack one back onto the fairway. He starts on Erin Hills' back nine, teeing off on the 10th hole at 8:29 a.m. (7:29 local time) along with Jamie Lovemark and Michael Putnam.
