JOHANNESBURG – Louis Oosthuizen, the 2010 Open champion, led the South African Open by a shot after a 9-under 62 in the first round on Thursday.
Oosthuizen, playing his home Open for the first time in eight years, made a brilliant start at Randburg Golf Club in Johannesburg with nine birdies, including six in an eight-hole surge on the back nine, and no bogeys.
''It was one of those rounds where you don't really look at any scoreboard or your card, you just play,'' he said. ''I drove it really well and gave myself good opportunities to hit it close.''
Els, 49, had a run of five birdies in six holes from the seventh. His last victory at the South African Open was in 2010, and his previous win anywhere on the European Tour came in 2013.
The tournament is being played on the Firethorn Course and the Bushwillow Course. Players will have a round on each before the final 36 holes are held at Firethorn.
