Justin played college golf at Lamar University, Texas and represented his country as an amateur golfer. After graduating he earned his place on the Sunshine Tour on his first attempt, finishing third at the 2009 qualifying school.
Now, Justin is a seven-time winner of the Sunshine Tour having won his first tournament in his rookie year. Since then, there have only been three years in which he didn’t win at least one tournament. Currently he is a back to back winner of the Asian Tour and he has since won on the European Tour as well, so there is no doubt he can play.
