Thiem takes first career title in Nice

World number 42 Thiem, labelled one of the world's top prospects, lacked composure in the first set as he lost the tiebreak 10-8.

He took the only break of the match in the 12th game of the second set to level the tie, powering through the final set's decider 7-2.

The 21-year-old Thiem is on a third-round collision course with local favourite Gael Monfils should they both progress at the French Open.
