Goss won the 2012 Western Australia Open Championship on the PGA Tour of Australasia while still an amateur.
Goss was runner-up in the 2013 U.S. Amateur. He was the only amateur golfer to make the cut at the 2014 Masters Tournament and thus received low amateur honors.
Goss turned professional after the 2014 U.S. Open and made his professional debut at the next week’s Travelers Championship.
