Kevin Na, winner of the 2011 Shriners Hospitals for Children Open, turns 32.
Scott Simpson, winner of the 1987 US Open, turns 60. Simpson won seven times in all on the PGA Tour, and finished in the Top 10 of eight other Majors, including second place at the US Open in 1991. In 1987, Simpson was two strokes off the lead after two rounds, but part of 11 men within striking distance, including former champions Tom Watson and Jack Nicklaus. He closed within a stroke of Watson at the end of 54 holes, and took the lead with a 30-foot birdie on No. 15. Playing ahead of Watson, he finished the final round with a 68, then saw Watson miss a 35-foot putt that would have forced a Monday playoff for the win.
Ryan Palmer, three-time PGA Tour winner, turns 39. Palmer finished tied for fifth at the 2014 PGA Championship.
