Overcoming a disappointing third-round 74, homestanding Louis Oosthuizen closed with a sparkling six-under-par 66 to edge Scotland’s Scott Jamieson by one at the Volvo Golf Champions.  Oosthuizen began the final round five back of Jamieson, who was aiming for his second straight E Tour victory, having claimed the Nelson Championship in December.  But while Jamieson worked his way around the famed Durban Country Club layout in 72, Oosthuizen went out in 32, then took the lead, never to be relinquished, with his sixth birdie of the day at number 11.  Jamieson had a chance to force a playoff at the driveable par-4 18th but narrowly missed a chip for eagle.  First-round leader Thongchai Jaidee finished third, two shots back, while Padraig Harrington claimed solo fourth……………Rookie Russell Henley became the rare player to win his first start as a PGA Tour member, riding a red-hot putter to birdies on the final five holes at the Waialae Country Club to pull away to a three-shot victory in the Sony Open in Hawaii.  Henley, a two-time winner on the 2012 Web.com Tour, recorded three 63s (plus a Saturday 67) en route to a 256 aggregate, the second lowest in Tour history after Tommy Armour III’s epic 254 at the 2003 Texas Open.  Having previously appeared in two U.S. Opens (tying for 16th as an amateur in 2010), the ex-University of Georgia Bulldog began the final round tied with fellow rookie Scott Langley before making birdie at the first hole, then eventually opening up a close battle with his red-hot finish.  South African Tim Clark matched Henley’s Sunday 63 to take solo second (three shots back), while perennial Waialae favorite Charles Howell III and Langley shared third.
