Maybe Ty was sick...I found this on a message board, someone who went to the International wrote this about seeing Ty play in person:

"What's up with Ty Tryon? He's one of the youngest out there, if not the youngest in the field. Yet, after only 5 holes of golf, he's out of gas such that he had to lean on anything that he could lean on. He's breathing really hard. He looked like he just wanted to lie down. His body language clearly displayed that he couldn't handle all that walking. He didn't look sick, though. He just looked totally out of shape. Granted that it's about 7,500 ft above sea level and the International course is designed for hikers, but he was in much worse shape than any caddies out there with huge bags to carry."
