Louis Oosthuizen and Adam Scott shot 7-under 65s to lead the HSBC Champions after the first round Thursday.
Oosthuizen, the 2010 British Open winner, played a bogey-free round with seven birdies, while Scott finished his round with two birdies and an eagle on the par-5 ninth hole.
Two-time HSBC Champions winner Phil Mickelson was in a tie for third one shot back, along with Bubba Watson, Peter Hanson and Shane Lowry.
Both Oosthuizen and Scott took advantage of the pristine conditions and the five par-5 holes on the Jose Maria Olazabal-designed course at Mission Hills. Oosthuizen birdied all five, while Scott had four birdies to go along with his eagle.
''It was a solid day that all of a sudden turned into a really good day,'' Scott said. ''With five par-5s, it kind of sets up well for my game and the plan is to just take advantage of the 5s and hopefully hang in there with the leaders all week.''
