Cape Town - SA's top-ranked golfer Louis Oosthuizen has cracked the Top 20 on the world golf rankings following his finish at the Valspar Championship this past weekend.
The 36-year-old carded a final round of 2-under 69 to finish tied for second on 7-under for the tournament alongside American Jason Kokrak.
Oosthuizen, whose only PGA Tour win came at the 2010 Open Championship, finished a stroke adrift from eventual winner Paul Casey of England.
Oosthuizen cashed in on $589 600 (R8.5 million) for his efforts this past weekend and also moved up to 61st on the PGA Tour's FedEx Cup standings.
He collected his second top-five finish in his seventh start of the 2018/19 season, which included a tied for 5th at the CIMB Classic.
His runner-up finish saw Oosthuizen move up seven places to sit 20th on the world golf rankings.
Meanwhile, 2011 Masters champion Charl Schwartzel, who missed the cut this past weekend in Florida, dropped to 100th on the world golf rankings.
Justin Harding, who is on a quest to qualify for next month's Masters, dropped one spot down to 49th.
