Before Erin Hills, only six players had reached 10 under in 116 US Opens

There are five players this year to have reached 10-under par or better at the US Open, generally viewed as the hardest major test, just one fewer than the number who had managed the feat over the previous 116 years.

Third-round leader Brian Harman, along with compatriots Brooks Koepka and Rickie Fowler were joined by England's Tommy Fleetwood to reach or better the 10-under figure.

We take a look at the previous six members of the double-digit US Open club.

Gil Morgan, 1992, Pebble Beach

Morgan became the first player to reach the 10-under par mark in US Open history on the third hole of his third round. He went on to move into a seven-shot lead after the 12th of the third round only to collapse dramatically over the remaining holes and shoot 77.

On the Sunday, despite still holding the lead into the final round, Morgan was unable to cope with the expectation and carded an 81 with Tom Kite securing his first major.

Tiger Woods, 2000, Pebble Beach

Woods secured his first US Open success, his third major title, in convincing fashion winning by a record-setting 15 strokes over runners-up Ernie Els and Miguel Angel Jimenez.

The 14-time major winner reached the 10-under par figure on the final round at the California links based course compiling a final round 67 to reach 12-under par and become the first player to complete a US Open double digits under par.

Jim Furyk, 2003, Olympia Fields

Furyk, next year's Ryder Cup captain for the United States at Le Golf National, reached the 10-under mark with a 67 in the third round presenting himself with a three-shot lead over Australia's Stephen Leaney.

Furyk closed with a 72 to finish at eight-under par but was never really threatened during the final day's play.

Ricky Barnes, 2009, Bethpage

Bethpage had a par of 70 and Barnes started with rounds of 67 and 65 and reached 11-under par by the fourth hole on Saturday. By the turn, he had created a six-shot lead in the third round but fell back to eight-under at the end of the round.

The pressure on his shoulders to lift his first major proved too much for the American, who carded a disappointing six-over par 76 to finish at two-under par and two behind eventual winner Lucas Glover.

Rory McIlroy, 2011, Congressional

McIlroy's victory at Congressional was all the more impressive as it came just a couple of months after his collapse at the Masters which threatened to derail his focus.

On a rain-softened course, McIlroy fired in numerous birdies to move up to a 14-under score by the Saturday and finished a full eight shots clear of Australia's Jason Day at 16-under par. Day's score would have been enough to win 26 of the previous 30 US Opens.

Martin Kaymer, 2014, Pinehurst

Kaymer opened his week with two rounds of 65-65 to reach 10-under and build a six-shot lead going into the weekend.

However, a 72 narrowed his lead before a final round 69 proved good enough for a very comfortable victory, finishing a full eight shots clear of his nearest rivals.
