Avoiding going winless in a year during which he generally played well, Sergio Garcia played four rounds of consistently fine golf en route to claiming the Thailand Golf Championship, his effort being good enough to vanquish the world’s hottest player, Henrik Stenson, by four.  Garcia trailed Thursday leader Alex Cejka by four after carding an opening 68, but he pushed himself directly into the fray with a Friday 65 over the Amata Spring Country Club layout, a round highlighted by a hole-in-one at the par-3 8th, and good enough to tie for the halfway lead with reigning U.S. Open champion Justin Rose.  Another 65 on Saturday then gave the 33-year-old Garcia some breathing room, as the eight-birdie effort pushed him four strokes ahead of Stenson, who passed all but Garcia with a Saturday 65 of his own.  Garcia – who played the entire event with his girlfriend on the bag – then birdied the 1st and 3rd holes on Sunday and while a bogey at the par-5 7th briefly slowed his momentum, a run of three straight birdies at holes 10-12 extended the lead well beyond even Stenson’s reach………………It was both fitting and sadly ironic that the Nelson Mandela Championship was played the very week of the great South African leader’s passing, with the event’s finish being moved to Saturday to avoid conflicting with his Sunday state funeral.  But the shift in schedule didn’t help the tournament to avoid being deluged by heavy rains for the second straight year – though where the 2012 playing could only complete 36 holes, this year managed to get in 54.  The winner was Dawie van der Walt, who began the third round three strokes behind England’s Daniel Brooks before posting a closing 66 that was keyed by an eagle at the 558-yard 12th, and a follow-up birdie at the par-4 13th.  An additional birdie at the 15th ultimately extended the margin of victory to two, with England’s Matthew Baldwin and Spain’s Jorge Campillo tying for second.  Equally notable was the scoring in a rain-delayed second round which extended from Thursday into Friday, most prominently the matching 59s posted by Campillo and South Africa’s Colin Nel.  These rounds, however, would not go into the European Tour record book as official as they were shot on a waterlogged layout whose par was lowered to 70, and under lift, clean and place conditions.
