Cauley whose career to date has been interrupted by shoulder injury and surgery, echoed the thoughts of many playing this event as to why he likes being on Hilton Head island.
“I love this place,” he said after his round. “It's different than anything else we play. It's a lot of fun to go out there and shape shots and kind of think your way around. Just a comfortable week. It's always nice. The weather is nice. I like the course. It's just a fun place to be, regardless of the golf."
