A look at the numbers of the top-five leaders after the second round of the U.S. Open, where Dustin Johnson is the only player in the red, and leads by four shots, at 4-under par.

Along with their top-line statistics and performance on the different sets of holes, we track their performance through the famous middle stretch at Shinnecock Hills (Nos. 7-12).

Raymond Floyd, the winner of the 1986 U.S. Open at Shinnecock, believes these six holes need to be played to even-par. Of the top-five players, only Jason Dufner finished over-par.

“The toughest stretch at Shinnecock is the middle six holes, 7 through 12,” Raymond Floyd told the NY Times in advance of the 2004 Open. “To win, I think you have to play those middle six holes in even par over four rounds. The prevailing left-to-right wind affects you on 7, 8, 9 and 10, then 11 and 12 are by no means easy.”

“I mean, the golf course was — it was hard. I mean, you had to play good golf if you wanted to shoot a good score. You know, I felt like I did everything pretty well today. I drove it well. I, you know, hit a lot of quality iron shots, and then my short game was good,” -Dustin Johnson

“I’ve been hitting fairways for the most part, which is good for me. And then was able to capitalize and hit greens after that. So giving myself opportunities. You don’t get really a ton of kick-ins here at Shinnecock. So opportunities from 20 to 30 feet, the percentages, the more opportunities you have, the percentages are going to go higher to make a birdie,” – Charley Hoffman

“Well, yeah. I mean, it’s easy to talk about it and dwell on it and kind of chew it over. When you’re out of position on this golf course and, you know, you’re trying not to make another mistake and another mistake and you kind of are, you know, it just looks really stupid. So, yes, I felt stupid knifing the first one. I felt even more stupid semi-chunking the next one, and I didn’t do much better on the next one either,” – Ian Poulter

“I still don’t feel like I’ve played that great tee-to-green. I’ve hit a lot of fairways and a lot of greens, but it’s still been — you know, not the quality of strike that I would have liked to have and the control of the direction all the time,” – Henrik Stenson

“Well, I mean I like — I do like the setup of a U.S. Open. It is the ultimate test of golf in more ways than one. It tests your long game, short game, every aspect. It tests you mentally, physically. If you’re going to win a U.S. Open, which is one of the biggest events in the world, it should be that kind of test,” – Tommy Fleetwood
