There are 138 of them covering what will be the first par-72 test at a U.S. Open since Pebble Beach in 1992.
The sky brightened by the afternoon as Dustin Johnson, the No. 1 player, arrived at Erin Hills. How can we play a match under those conditions? Spieth won the tournament in 2015 and McIlroy did in 2011.
"Just a mental test, just dealing with the mental side of the game more than any other tournament", said American Jordan Spieth, victor of the 2015 US Open on a similar links style course at Chambers Bay. "I see closer to five- to 10-under".
Asked about winning another major, McDowell said, "Maybe it came to me in 2010 a little earlier than I expected but there is no doubt I had a dream and I believed that I had the game to win a major championship". Erin Hills is proof of the existence of course bifurcation.
Johnson has the power to outdrive the competition on almost every hole. He missed a 4-foot birdie putt on the bumpy green. If his putting is sharp, he should have an excellent chance to win a second consecutive tournament.
"Really?" McIlroy said during his news conference. "By the time it tees off, we'll be more than 25 percent of the Masters but will probably fall short of 50".
McIlroy is somewhat inconsistent in that he rarely has all elements working together at the same time.
Wallace has received plenty of advice as he prepares to tackle Erin Hills alongside the world's best. And given his luck with major championship rental homes this year, this activity could be construed as hazardous. Like Johnson, a huge burden was lifted when he was able to hold his game together in the final round. In that department, Erin Hills' closing par-5 18th fits that bill to perfection. The last group is scheduled to tee off at 3:42 p.m. ET.
With Tiger Woods absent, still struggling to resurrect his career after back surgery, and Phil Mickelson likely to skip the tournament to attend his daughter's high school graduation, this year's US Open could mark the end of an era. A bettor who wagers $100 on Johnson will earn a profit of $750 if the defending champion is successful. Since then, there has been nothing but first-time winners at the majors - Jason Day, Danny Willett, Dustin Johnson, Henrik Stenson, Jimmy Walker and Sergio Garcia.
While the USGA and organisers believe they have prepared for nearly every contingency Davis admitted you never know what can happen.
"When I get a break I'll look at getting my own place, but for now I'm just loving the ride and they have been so important to me".
It is, simply put, a really good closing hole. So coming up with a winning score, never mind a victor, is perhaps a little more hard than in past years.
While it was not a long-term injury, it kept him from competing. Us Weekly has learned that it was Johnson's grandfather and former L.A. Lakers player Art Whisnant who gave O'Connor consent to publish the photo online.
"Wherever DJ plays, he's the longest out there".
Johnson will keep it together throughout the tournament and find a way to play his best round on Sunday. American young guns world number five Jordan Spieth, the 2015 U.S. Open victor, and number nine Rickie Fowler, zeroing in on a maiden major, will spearhead the American charge along with Johnson.
