Jamie Lovemark (68) is his closest challenger on nine-under, but the gap could be cut when some players finish their rounds after the second round had to be suspended due to darkness.
Roberto Castro and Welshman Jamie Donaldson are two behind Hoffman with three holes still to play, with Donaldson on for the low round as he is already five-under through 15 holes.
