The US Open at Oakmont proved to be a real war of attrition.
J.J. Spaun was the last man standing at Oakmont, after holing a 64-foot putt to win the U.S. Open in real style.
Oakmont was well known as being an incredibly difficult golf course before the week began.
And many of the best players in the world really struggled around the Gil Hanse restored track.
Oakmont claimed numerous high-profile victims, with the likes of Bryson DeChambeau, Ludvig Aberg and Justin Thomas all missing the cut.

So considering the fact that some of the world’s best golfers struggled around Oakmont, it’s no surprise that average amateur players might find the course nigh-on impossible to score around.
One-handicap golfer Braden Newcomer shot 93 at Oakmont last week, and this week, it was the turn of SiriusXM PGA TOUR Radio producer Mike McCann to have a shot at taming the beast.
What a 10 handicap amateur shot around Oakmont after the US Open
McCann currently holds a handicap of 10.
In fairness to him, he would actually receive 21 strokes at Oakmont with that handicap, according to the USGA’s course handicap calculator.
So a round of 92 would be around par for McCann (the members play Oakmont as a par 71).
However, did he beat that score, or get anywhere close to it in fact?

The answer to that question is no, unfortunately for McCann. The SiriusXM PGA TOUR Radio producer carded a round of 105 – a whopping 34-over par.
He played off the members tees (around 6,600 yards), with the course playing to a par of 71.
The seven worst scores at Oakmont during the 2025 U.S. Open
The average score for the 156 players in the field for the entire week was 74.10.
However, that average went down after the first two rounds, when the field was trimmed to 66 players.
There were some real horror shows on display during the first two rounds of the U.S. Open. Here are the seven worst scores that were posted at Oakmont:
| Score | Player | Round |
| 89 | George Dunagmanee | 2 |
| 86 | George Dunagmanee | 1 |
| 85 | Brady Calkins | 2 |
| 85 | Roberto Diaz | 1 |
| 84 | Justin Lower | 2 |
| 84 | Justin Hicks | 1 |
| 84 | Will Chandler | 2 |
Those scores highlight just how difficult Oakmont was playing during the U.S. Open.
You have to be seriously good to tee it up in America’s national championship, and none of the players competing got there by luck.
Taking that into account, Mike McCann’s round of 105 really wasn’t as bad as it seems, although he undoubtedly would have been hoping for a lot better.
