Rain and fog prevented Tiger Woods marking his US tour return in style - but Northern Ireland's Darren Clarke managed a hole-in-one before bad weather brought the first round to an early close at the Buick Invitational in La Jolla, California.
The first-day honours went to rookie Arron Oberholser, who held a one-shot lead when rain forced a terminal suspension at Torrey Pines club.
Fog delayed the round for more than four hours early in the day before rain took over, preventing anyone in the 156-player field from finishing 18 holes.
Oberholser was among the closest to finishing, playing 16 bogey-free holes in six-under par for a one-stroke edge over Skip Kendall.
The early tournament leader was the top collegiate rival of Woods, who made his annual tour debut today after undergoing knee surgery in December.
Woods struggled in the rain, but still played nine holes in one under.
Eight players were two strokes off the lead at four under - including Clarke, whose hole-in-one came on the par-three third on the North Course.
