MARANA, Ariz. -- Sweden's Alexander Noren, a 13th seed, beat fourth-seeded Dustin Johnson of the U.S., 6 and 4, in the first round.
Noren, making just his second start in this event, will now play Graeme McDowell in the second round of the Jones bracket.
After a bogey on the first hole, Noren played as well as anybody on the course Thursday. He was bogey-free for the rest of the round and posted seven birdies on his card. He was 3 up through six holes, 4 up through eight, and played even better on the back nine.
He reeled off four consecutive birdies starting at the 10th hole, making bbirdie putts of 6-1/2 feet, 9 feet, 2-1/2 feet and 4 feet.
"I played great," Noren said. "I was really happy with my game and hit a lot of greens ... It was a lot of fun."
