Louis Oosthuizen shook things up on Friday when he shot 63 at the WGC-HSBC Champions tournament and matched the Sheshan International Golf Club course record.
Oosthuizen raced to 10-under-par, moving 28 spots up the leaderboard and into a share of second, one stroke shy of Fredrik Jacobson, who leads the $7000000 event after 36 holes.
The 2010 Open Champion could do no wrong Â he dotted his card with nine birdies and dodged bogeys throughout the round to become the fourth-ever player to shoot nine-under at the Shanghai golf course.
The record was established in 2009 by Diasuke Maruyama and in the same year Ernie Els and Rory McIlroy matched it. The day started well for Oosthuizen when he shot consecutive birdies at the second and third.
But the pair would not satisfy the 29-year-old and he penciled in a hattrick of birdies from the sixth to the eighth. He took just 31 strokes to cover the front stretch and turned at five-under.
Through the 12th and 13th Oosthuizen shot his second pair of birdies for the day.
He went on to birdie the 16th before fittingly closing the day by boxing a 15-footer at the 18th for the final birdie of his round.
Every facet of OosthuizenÂs game was on form during Friday and resulted in birdies all over the show Â three came at par-fives, four came at par-fours and two came at par-threes.
Charl Schwartzel also birdied the 18th, but his second-round card read 69 and earned him a move to tied 18th at five-under-par.
Schwartzel will partner Oosthuizen at the Omega Mission Hills World Cup of Golf starting 27 November. The pair of major winners are good friends and have played golf together since their amateur days in South Africa, which makes them a formidable team.
King LouisÂ victory at The Open proved that he can outstrip the competition if left unchecked, and by blasting to the course record this week has declared himself a real threat in Shanghai.
