Louis played the Maybank Malaysian Open, which took place at Kuala Lumpur Golf & Country Club, and claimed his fifth victory on the European Tour.

Having narrowly missed out on victory at Augusta seven days earlier, the South African responded in fine style, shooting rounds of 66, 68, 69 and 68 to finish the tournament on 17 under par, three shots clear of second.

“I thought I was going to be a lot more tired,” said Oosthuizen, “It was a long journey to get here and I have to be honest and say that I didn't expect to play this well because of the tiredness.

“The one thing I did know was that the game was there so that helped a lot. I was pretty tired at points in those first couple of rounds but overall it has been great and I am over the moon with the result.

"On Thursday I knew the game was there - it was just a question of whether or not I would be able to go all the way physically.

"Having a good week this week was important and playing well. I didn't want to come here and play bad but to win means a lot because I have been playing well for the last few weeks now and to win gives me a lot of confidence for the rest of the season.”
