Louis Oosthuizen: Who is the man in contention for The Open?

Who is the man tied for 1st place going into the final round?

Louis Oosthuizen is in contention to win The Open heading into the final day of play at St Andrews, tied for 1st place with Irish amateur Paul Dunne and Australia's Jason Day on -12.

Here, we take a closer look at the player whose Open title push gets underway at 14:30:

Oosthuizen has previous success at The Open, he won the tournament in 2010 - the last time the tournament was at St Andrews - by the huge margin of seven strokes, as he finished on -16, ahead of England's Lee Westwood.

Since then however he has never finished any higher than equal 19th in the tournament, although he has always made the cut.

The Open remains the only major that Oosthuizen has ever won, although he did come second at the Masters in 2012, and was tied for second place in last month's US Open, Jordan Spieth just pipping him and Dustin Johnson to the title by one stroke.

As the US Open showed, he is currently in some good form, having strung together his longest succession of cuts made, now standing at seven, stretching back to the 2014 Masters.

The highest Oosthuizen has ever reached in the Official World Golf Ranking is 4th, in January 2013, although he now currently sits in 17th place.

However that does make him the highest ranked South African, his next best countryman Branden Grace ranked 29th.

His full name is Lodewicus Theodorus Oosthuizen although he has the nickname "Shrek".

"It's the gap in the teeth," Oosthuizen said. "My friends say I look like Shrek -- some of my friends -- and you can't choose your friends, so what can I say?"
