Singh among early co-leaders at Northern Trust


Conditions were ideal in the first round at Riviera, but one of the PGA Tour's oldest tracks proved a stern test. Here's how things look after the opening day of the Northern Trust Open, where six players share the lead:

Leaderboard: Vijay Singh (-5), Retief Goosen (-5), Nick Watney (-5), James Hahn (-5), Derek Fathauer (-5), Daniel Summerhays (-5), Carlos Ortiz (-4), Justin Thomas (-3)

What it means: Singh and Goosen both turned back the clock Thursday, as the two major champions moved to the top of the standings despite a combined age of 97. The co-leaders include a trio of players in search of their first win along with a resurgent, who was a runner-up last week at Pebble Beach.

Round of the day: Singh carded six birdies against just one bogey during his opening-round 66, including four birdies from Nos. 10-16. The 52-year-old, whose last win came at the 2008 Deutsche Bank Championship, now holds a share of the opening-round lead for the first time since the 2012 Greenbrier Classic.

Best of the rest: Goosen has two U.S. Open titles to his credit, but the South African hasn't won on the PGA Tour since the Valspar Championship in 2009. He took a step toward ending that drought with an opening 66, a round that included seven birdies and 11 one-putt greens.

Biggest disappointment: Luke Donald had high hopes for a bounceback in 2015, but the Englishman continued to struggle Thursday at Riviera. Donald opened with a 6-over 77 to drop 11 shots off the pace and now appears to be headed for his third consecutive missed cut.

Main storyline heading into Friday: The veterans at the top of the standings will receive plenty of attention, but the player to watch may be Watney, who successfully brought the momentum with him from Pebble Beach. After a disappointing 2014, Watney is in contention for the second straight week and now eyes his first win since The Barclays in 2012.

Quote of the day: "It's easy to kind of go out there on Thursday and just think good things are going to happen just because you played well the week before. But you have to reset and get back to when you were doing and hopefully you can have a chance again in the new week.” - Watney
