Coric followed that up with victory over Murray, the 2012 U.S. Open and 2013 Wimbledon winner, at the Dubai Championships in February 2015.
Rising star —
"I felt very proud and I'm still very proud, it's an unbelievable thing," he told CNN's Open Court show of those acclaimed victories. "It gave me confidence that I can play with these big guys. I started to believe even more that I can become a top 10 tennis player."
Junior champ —
Coric took up the game aged five when he saw his father play, and went on to win the 2013 U.S. Open junior boys' title.
