As the No. 1 amateur player in the world, Patrick Cantlay is a golfer a lot of people are talking about.
The UCLA Bruin has enjoyed a fruitful 2011 which included an appearance for the United States at the Walker Cup.
At just 19, Cantlay qualified for the 2011 U.S. Open. He went on to make the cut and finish tied for 21st—the best finish by an amateur.
He showed his undoubted potential again at the PGA Tour's Travelers Championship in June where he set a course record 60.
The Californian also won the Haskins Award as the most outstanding college golfer in 2011.
Cantlay shows experience and confidence on the course that belies his age and he has shown no sign of letting his early success go to his head.
He plans to see out his full college career before turning professional.
