Southampton - Louis Oosthuizen finished as the best South African golfer at the 118th US Open at Shinnecock Hills Golf Club.
Out of the six South Africans who teed off at the start of the tournament, only three made the cut for weekend.
Oosthuizen posted his first under-par round for the week, as he shot a 1-under 69 on Sunday to finish at 10-over par for the tournament.
He finished tied for 16th, nine shots behind eventual champion, American Brooks Koepka, who claimed back-to-back US Open titles.
"It was a lot easier than yesterday in the way they set up the golf course," Oosthuizen told Sport24 after his final round.
"I'm happy, I'm 1-under today and any round close to level par is good around this golf course."

Branden Grace carded 5-over 75 to finish 12-over par for the tournament - and lie tied for 25th.
Playing in his first Major event, Dean Burmester went 4-over 74 in his round to end 17-over par at Shinnecock Hills.
The other South Africans participating - Charl Schwartzel, Dylan Frittelli and two-time US Open winner Ernie Els - failed to make the cut.
