SUN CITY, South Africa Dec 6 (Reuters) - A freak penalty stroke did little to deter Welshman Jamie Donaldson as he posted a second-round 66 at the Nedbank Golf Challenge on Friday to top the leaderboard with an 11-under-par total of 133.
A storming outward 31, including five birdies, gave Donaldson a three-stroke halfway lead at the Gary Player Country Club on a sombre day following the death of former South Africa president Nelson Mandela.
Friday's early start was preceded by a minute's silence in honour of the 95-year-old statesman as the elite 30-man field resumed their weather-interrupted first rounds from Thursday.
Sergio Garcia finished as first-round leader after a blistering morning start as he posted a 66 but Donaldson was already out on the course again, picking up three birdies in his first four holes.
On the par-five 10th, he carded a bogey six after picking up an unusual penalty.
"It was mad, I just pushed my tee shot a little bit into the green-side trap and tried to move it about 100 yards down the fairway but it clipped the lip and as the ball sort of came back I hit it again with my shaft, over my shoulder, back into the bunker," the Welshman told reporters.
The referee's ruling was a one-shot penalty but Donaldson recovered to sink two more birdies to finish six-under for the round.
His 66 was only bettered by American Ryan Moore, who made seven birdies in a second-round 65 that took him eight-under and into joint second place with Sweden's Henrik Stenson.
