Most of all, it’s like I’m a 12 year old at Disney. I was walking in for my practice round and I was feeling butterflies, due to my excitement,  just looking at everything. It’s the dream that everybody has as a golfer.”

Roberto Diaz has been training with Greg Norman Champions Golf Academy for several years.
