While fog delayed the opening round of the Genesis Open, eventually the skies parted and allowed Sam Saunders to vault to the top of the standings. Here's how things stand after the first day at Riviera Country Club, where Saunders leads by two shots:
Leaderboard: Sam Saunders (-7), Dustin Johnson (-5), Daniel Summerhays (-5), J.T. Poston (-5), Brett Stegmaier (-5), Cameron Percy (-5), Phil Mickelson (-4)
What it means: Once the fog burned up, several players were able to take advantage of relatively benign conditions at Riviera.
