Spieth opens with 79; Villegas leads Riviera with 63

LOS ANGELES (AP) Jordan Spieth was everywhere he wasn't supposed to be at Riviera and wound up with a 79 in the Northern Trust Open.

Spieth called it a day to forget. It was his worst score since an 80 in the 2014 Tour Championship.

For Camilo Villegas, it was a day to savor. The Colombian ran off four straight birdies late in his round and challenged the course record until a bogey on his final hole for a 63. He led by three shots over Bubba Watson, Chez Reavie and Luke List.

Spieth ended his round with a three-putt from 8 feet for a double bogey. And there's still a chance it could be worse. Spieth asked rules officials to look at video of his third shot on the ninth hole to make sure it didn't move.
