ST. ANDREWS, Scotland (AP) Louis Oosthuizen has won his first major golf championship with a dominating seven-stroke victory at the British Open.
The South African started Sunday with a four-stroke advantage. It turned into a romp when his closest challenger, England’s Paul Casey, took triple-bogey at the 12th.
Oosthuizen shot a 1-under 71 in the final round for a 16-under 272 total.
He had a chance to tie the modern Open record for the biggest win, an eight-stroke margin last accomplished by Tiger Woods a decade ago at St. Andrews.
But the 27-year-old missed a 10-foot birdie attempt at the final hole and tapped in for par.
Englishman Lee Westwood shot 70 and wound up the runner-up at 279.
Casey staggered to a final round 75 and finished at 280, tied for third with Northern Ireland’s Rory McIlroy and Sweden’s Henrik Stenson.
No one got within three strokes of Oosthuizen all day. Coming into the week, he had made the cut in only one of his previous eight majors.
