with round one of the Northern Trust Open suspended due to darkness.
Singh, who will turn 52-years-old on Sunday, and Goosen, 46, were joined atop the leaderboard at Riviera Country Club by last week's runner-up Nick Watney, James Hahn, Derek Fathauer and Daniel Summerhays.
Carlos Ortiz is alone in seventh place at minus-4. Justin Thomas, Alex Cejka, William McGirt and Geoff Ogilvy are one stroke back at 3-under 68.
Jordan Spieth opened to a 2-under 69 and he headlines a group of five players that share 12th place.
Defending champion Bubba Watson birdied the 18th for a 1-under 70. He is among a large group tied for 17th.
