It didn’t take Jordan Spieth very long to quickly warm up on a chilly Thursday morning north of Los Angeles.
Starting on the back nine, he birdied his first two holes in the opening round of the Genesis Invitational hosted by Tiger Woods at Riviera Country Club. And after the sun finally broke through the clouds and the thermometer passed 60 degrees, Spieth had a total of seven birdies to offset two bogeys and signed for a 5-under 66.
