The Canadian Press Si Woo Kim , The Canadian Press LA QUINTA, Calif. — Si Woo Kim birdied two of the final three holes to finish a rock-solid, 8-under 64, coolly rallying past late-charging Patrick Cantlay by one shot to win The American Express on Sunday for his third PGA Tour victory. A year after Kim withdrew from the desert tournament because of a back injury following an awful first round, he began the final round with a share of the lead as he attempted to win for the first time since the 2017 Players Championship.
