Louis Oosthuizen is looking for a double celebration as he defends his title at the Africa Open and waits the birth of his second child.

The 2010 Open champion is just hoping this week’s tournament will be done and dusted by the time his wife Nel-Mare goes into labour.

Last year, Oosthuizen beat ISM stablemate Chris Wood and Spaniard Manuel Quiros in a play-off to win the event at East London Golf Club in South Africa.

“It is always fun defending a title so I’m just hoping that the week runs smoothly and that I don’t get a phone call from Nel-Mare or the doctor telling me to come home!” he said.

“But, funnily enough, sometimes it’s good to have your thoughts elsewhere and not solely on the golf. Of course, I’ll be focused on what I have to do on the course but in the back of my mind I’ll always be mentally checking on what’s going on at home.

“Obviously winning The Open was a dream come true for me but it was always a dream of mine as well to win a co-sanctioned tournament on The European Tour back home in South Africa. I had come close in the past at the Dunhill a few years back when Ernie won and in the SA Open the year James Kingston won, so to do it at East London last year was very satisfying.”

The 29-year-old said the key to success is finding the right areas on the fairways.

“It’s a course where there are not a lot of driver holes and you should try and keep it low if you can, he said.

“There are some tight fairways so you have to be careful, but it’s also a golf course where, if you take it on and succeed, you can really shoot low numbers. It is not a long course, it is all position.”

Oosthuizen is one of 12 ISM players in the field for the tournament which starts on Thursday.
