Britain number one Andy Murray suffered a crushing defeat on Thursday as he was thrashed 6-1, 6-3 by Croatian teenage opponent Borna Coric in the Dubai Championships quarter-finals.
The two-time Grand Slam champion made 55 unforced errors during his match against Coris, who will next face world number two Roger Federer in the semi-final.
In light of his performance, Coris said that it was one of the biggest wins, adding that he was just trying to maintain his level, stay in the rallies as long as he could, the BBC reported.
Murray, who finished runner-up in this year's Australian Open, said that he made way too many mistakes from the beginning of the match right through to the end, early in rallies, rushing points.
Coris is the youngest player to feature in the men's top 100 and is the first teenager to reach the Dubai semi-finals since Rafael Nadal bagged the title as a 19-year-old in 2006.
