Golf:Pádraig Harrington again faltered in sight of the clubhouse at the Volvo Golf Champions in South Africa as back-to-back bogeys on the 16th and 17th and another double-bogey on the last saw him drop back down the leaderboard at Fancourt.

A double-bogey on the 18th had undone his opening round after he had carded six birdies, but after dropping a shot on the sixth this morning, he put together five birdies in eight holes from the eighth to move to eight under and a share of third place.

His round unravelled after that, with bogeys on the par-five 16th and the short 17th before closing for the second day with a seven on the final hole as he took three putts to navigate the treacherous green. That all added up to a level-par 73 and he remains on four under for the tournament.

British Open champion Darren Clarke carded seven birdies and two bogeys in a five-under-par 68 that moved him to four under for the tournament, while Michael Hoey improved on his opening 78 when carding a one-under 72 to lie on four over for the tournament.

South African Branden Grace moved to the top of the leaderboard on 12 under after a brilliant seven-under-par round of 66 that included eight birdies and just a single dropped shot.

Overnight leader Nicolas Colsaerts went out in 40 and was five over for his round after 14 holes before making birdies and the 16th and 17th to sign for a three-over 76 to fall back to six under.
