Retief Goosen and Vijay Singh were among the top five players in the world 10 years ago. Now they are part of a five-way tie for the lead in the Northern Trust Open.

In what amounted to throwback Thursday at Riviera, Goosen and Singh each made a pair of birdies late in the round for a 5-under 66. They were tied among the early starters with Pebble Beach runner-up Nick Watney, Daniel Summerhays and James Hahn.

The 51-year-old Singh hasn't won since 2008 and splits time on the Champions Tour. Goosen is 46, a two-time U.S. Open champion who hasn't won since 2009. Both are ranked outside the top 200 now.

Singh and Goosen played in the same group with 28-year-old Brian Harman, who shot a 78.
