Delaware County golfer Braden Shattuck is gearing up for the PGA Championship this weekend, and he's bringing a uniquely local story with him. Walking beside him will be his caddie, Beau Riviere, who just turned 18 and is officially the youngest caddie in the entire 156-person field. Riviere grew up in the heart of Philadelphia. He's a strong golfer in his own right, but for the past year, he's been caddying for Shattuck at Rolling Green Golf Club.
