Cape Town - South Africa’s Louis Oosthuzien has jumped seven spots to No 11 in the official world golf rankings.
Oosthuizen lost 5 and 4 to Australia’s Jason Day in the title match of the World Match Play tournament in Texas on Sunday.
For his efforts, Oosthuizen rose from No 18 to No 11 in the rankings, with compatriot Branden Grace moving down one spot to No 13.
Day, meanwhile, regained the world No 1 spot following his victory.
He takes over at the top from Jordan Spieth, who lost in the round of 16 in the Match Play. The 22-year-old American had been at the top since winning the Tour Championship at the end of September and moving ahead of Day.
Rory McIlroy, who lost in the semi-finals to Day in Austin, stays at No 3 with the first of the year's four majors, the Masters, fast approaching in two weeks' time.
