Spieth opened the year by winning the Hyundai Tournament of Champions by eight strokes, but at Riviera he looked out of sorts and his swing was out of rhythm, the product of not finishing his backswing. Whether he sorts it out entirely is not as important as being ready in April for the year's first major. That's not to say he doesn't want to play well this week in an $8.5 million event. But majors are his focus, as he proved last year by winning the U.S. Open as well as the Masters and coming close in the British Open and PGA Championship.
