Dustin Johnson claimed victory at the 116th U.S. Open while Jason Day recorded another top-10 finish.

Jason DayAfter opening his U.S. Open tournament with a 6-over 76 to be T100th, World Number 1 Jason Day fought back at Oakmont.

Rounds of 69, 66 had Day within a sniff of contention heading into the final round but it was on the back-9 where Aussie fans really started to get excited.

Coming through the turn 1-over the card, Jason Day displayed some of the magic which has made him the top player in the world.

Chipping in for an eagle on the par-5 12th, the crowds at Oakmont erupted as Day was under par for the first time in the tournament.

Day backed this up with a birdie at the 13th and looked like he might be able to challenge the leaders on his way home.

However, Aussie hopes were dashed when Day double bogeyed the 17th and closed his U.S. Open campaign with a bogey on the 18th.

"I had to push. You can't win tournaments just laying up there. I had the opportunity to go out there and give myself the shot at winning the tournament," said Day, about his mentality on the 17th.

"I tried to hit a good shot there. Hit a great drive. Unfortunately, it didn't work out."

"I've got to understand that these things happen for a reason and not be too disappointed."

"Where I was hitting after my first round, shooting 6-over par, to where I am now, trying to fight my way back in and giving myself an opportunity at winning, especially on a U.S. Open course, it takes a lot of grit and a lot of oomph to get there."

Recording a tournament total of 2-over 282, Day finished in a tie for 8th, the MyGolf Ambassador racking up his 5th top-10 result in six starts at the Major.

"I keep having a lot of top-10s in U.S. Opens. I've had two second place finishes already. Now a fourth, a ninth and an eighth," added Day.

"I've just got to keep doing what I'm doing because obviously I'm putting myself in contention to give myself a shot at winning."

"So one of these years, it's going to fall my way. Until then I've got to keep working hard, keep being focused on the process and trying to get better each and every week."

Marc Leishman and Adam Scott were the next best of the Aussie contingent finishing tied 18th on 6-over the card, after shooting final rounds of 1-under and 4-over respectively.

Cameron Smith, who was in the field after his stellar performance at last year's U.S. Open, couldn't manage the same result this year and finished in a share of 59th on 15-over the card after shooting a 79 in the final round.

While Aussie fans were hoping to see another Aussie Major Champion, the tournament belonged to Dustin Johnson who prevailed under a swirl of controversy.

In contention and with a share of the lead throughout the entire final round, Johnson was informed by USGA officials that he would be assessed for a potential penalty after his round.

On the 5th green, Johnson's ball moved before he addressed it. Johnson, his card marker Lee Westwood and the walking rules official all agreed Johnson did not cause the ball to move.

However on the 12th tee a USGA official informed Johnson that the committee would be reviewing the decision after his round.

While this hung over his head, Johnson remained calm under pressure sinking a birdie putt on the 18th to ensure he had a four shot lead heading to score recording. The USGA did in fact enforce a penalty on Johnson.

However, Johnson remains the 116th U.S. Open champion with scores of 67, 69, 71 and 69 to win by three shots from Jim Furyk, Scott Piercy and Shane Lowry.
