When Louis Oosthuizen walks on to the first tee at St Andrews in Scotland tomorrow, memories of his 2010 British Open victory at the Home of Golf will come flooding back as he bids for a repeat performance. The South African led over the final 48 holes at the Old Course five years ago, blowing away the rest of the field to win the Open by seven shots."It's great to be back here," Oosthuizen told reporters yesterday."The biggest memory was I think on Monday walking down 18, seeing the grandstands and remembering that moment walking in 2010 on the Sunday afternoon."It will give me the confidence knowing what I've done here and that I can play this golf course."But you still need to go out and make a good score and play good golf around this track."If you're not going to be driving the ball well you're going to find a few pot bunkers and you're going to make mistakes. You're going to make bogeys," said Oosthuizen.The 32-year-old is in good form having tied for second place at the US Open last month.Oosthuizen will partner former world No1 Tiger Woods and Australian Jason Day in the opening round. ..
