South African Louis Oosthuizen returned to Torrey Pines early on Friday to put the finishing touches on his first round with a pair of pars that left him in a two-way share of the US Open lead with Russell Henley.

Oosthuizen was among the 36 players who were still on the course and unable to complete the round before play was halted due to darkness on Thursday.

The former British Open champion, who began his round on the back nine, showed no ill effects of the interruption as he found the green with his tee shot at the par-three eighth where he two-putted from 34 feet.

Oosthuizen’s opening four-under-par 67 left him level with Henley.
