Borna to do it – Borna Coric is making his name as the most talked-about teenager in tennis.
Being extraordinary – He is the youngest player in the top 100 at the age of 18, having already beaten 14-time grand slam champion Rafael Nadal and Andy Murray, a double major winner.
Nadal breakthrough – His breakthrough victory came in Basel in November 2014 when he beat Spain's Nadal. He became the first 17-year-old to get into double digits in the rankings since 2004.
Murray bested – 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.
Croatian mentor – Coric counts 2001 Wimbledon champion Goran Ivanisevic as his mentor. The former world No. 2 guided compatriot Marin Cilic to U.S. Open glory as his coach in 2014, and told CNN that Coric can also can win a grand slam.
Number one target – Coric couldn't repeat his defeat of Nadal when they met in the first round of the 2015 U.S. Open but he has set his goals high: "I think everyone's goal is to be No. 1 in the world."
