Louis Oosthuizen's final birdie on the 17th hole on Sunday was enough to propel him to a second straight Africa Open title over upstart Tjaart Van Der Walt.

Oosthuizen finished the final round with his second straight six-under 67, giving him a tournament-record 27-under 265 over 72 holes at East London Golf Club. It's the fourth title overall for the South African, becoming the first player to repeat at this event in its brief five-year history.

The top two finishers were neck and neck all afternoon, even with only two holes to play. Oosthuizen finally squeaked ahead with a birdie on the par- three 17th, while Van Der Walt's bogey on the same hole all but decided the tournament.

Both parred the last to give Oosthuizen the title.

Van Der Walt (69) still put together a fine runner-up performance at 25-under 267, but he was denied his first European Tour title. Retief Goosen, who won the 2009 Africa Open when it was sanctioned by only the Sunshine Tour, shot a four-under 69 Sunday and finished third at minus-24.

Jaco Van Zyl (66) was fourth at 23-under, while Alastair Forsyth (67) was fifth at minus-22.
