At 84 in the world, Coric is the youngest player in the top 100, and after beating Rafael Nadal at the Swiss Open last October, he achieved arguably an even greater feat by defeating Murray with a composed, professional display to reach his second tour semi-final.
The opening set included a scintialting 41-shot rally which Murray won, but that was about as good as it got for the former Wimbledon champion.
Speedy 18-year-old Coric went on to break the British No 1’s serve three times, winning 31 points, while an out-of-sorts Murray made 27 unforced errors ??? he ended the match with 55 in total.
Lucky loser Coric made it to the quarter-finals after Marcos Baghdatis retired with cramp in a final set tie-break after almost three hours on court, while Murray dismantled Joao Sousa for the loss of two games to set up a first ATP Tour meeting with the youngster.
But Murray, who beat his opponent in a Davis Cup match two years ago, was being completely outplayed on the hard court.
Coric was playing some inspired tennis and crucially broke in the sixth game of the second set with a stunning lob before holding his nerve on serve to close out a famous win for the loss of just four game in one hour and 19 minutes.
The teenager’s reward for claiming Murray’s scalp could be a semi-final match against Roger Federer, providing the world No 2 can successfully overcome Richard Gasquet later.
