"When he first came to me he could hit it a long way, knew his game and could get the ball in the hole," Hahn said. "Unfortunately, when he made a mistake he wasn't able to fix himself."
So, Hahn brought pictures and videos and worked with Wheatley on fundamentals such as changing stance and how far to stand from the ball.
"[Wheatley] had an unorthodox swing to now one of a golfer you'd see on the [PGA] Tour," Hahn said.
Wheatley acknowledges the obstacles golf presents and how to respond.
"The most challenging part is handling the bad days and taking the positives out of it." Wheatley said. "You have to take a deep breath, trust yourself to get back rather than trying to hit a one-in-a-million shot."
