Louis takes the lead again

New British Open champion Louis Oosthuizen sits at the top of the leaderboard after the first round of the Scandinavian Masters alongside Australia's Richard Green and Dustin Johnson of the United States, after shooting a 5-under 67 on Thursday.

Just four days after his runaway victory at St. Andrews, Oosthuizen started full of confidence on an overcast, breezy day at the Bro Hof Slott course with a birdie at the par-5 578-yard first hole.

The South African finished the front 9 in 1-under 35. He collected five more birdies on the back 9, but was unable to take the overall lead after a bogey at the 13th.

"I had a good sleep, but I woke up tired again and the (British Open) win has definitely drained me," Oosthuizen said. "But the crowds were unbelievable, cheering me on to every green and every tee. I wanted to play nicely. The last thing I wanted was to put on a bad show."

"I need a break. I need a week off before going to America," Oosthuizen added. "I don't think I'm (supposed to be) back to South Africa until September but I felt like I wanted to say hi to my family and see everyone before I go."
