Oosthuizen still in shock after Open win

Open champion Louis Oosthuizen has admitted it could take a week for his amazing victory at St Andrews to sink in.

Oosthuizen was a 200/1 outsider at the start of the 139th Open Championship, but ended up leaving the world's best golfers trailing in his wake with a stunning display.

The 27-year-old South African carded rounds of 65, 67, 69 and 71 for a 16-under-par total and stunning seven-shot winning margin over world number three Lee Westwood, with Paul Casey, Rory McIlroy and Henrik Stenson a shot further back.

After 12 holes of the final round Oosthuizen was 17 under par and in sight of the record low score in major history - 19 under par set by Tiger Woods here in 2000 - but with the Claret Jug effectively secured, he could simply concentrate on enjoying becoming the fourth South African Open champion after Bobby Locke, Gary Player and Ernie Els.

"It was unbelievable," admitted Oosthuizen. "After the 12th it became a bit difficult, having such a big lead, to stay calm and focused, but I'm glad I had an eight-shot lead on the 17th tee.

"I kept cool and calm the whole way but it's probably going to hit me tomorrow or next week what I've done."
