French Open: Novak Djokovic defeated Ricardas Berankis to keep his bid intact to be the first man in more than half a century to win all four majors on multiple occasions.
The Serbian second seed beats Marco Cecchinato, whom he had lost to in the French Open quarter-finals earlier this year.
Seventh seed Thiem is the first Austrian to make a final at the majors since Thomas Muster was champion in Paris in 1995.
Marco Cecchinato, who had never won a Grand Slam match in his career before the French Open 2018, will face Dominic Thiem for a place in Sunday's final.
