Dominic Thiem French Open 2020

WATCH: Dominic Thiem forced to retire with worrying injury while leading

Dominic Thiem was forced to retire with a wrist injury while leading Adrian Mannarino in his first match at the Mallorca Championships.

The world No. 5 withdrew from the second round contest against the Frenchman when up 5-2 in the first set, and at 15-15 on his opponent’s serve.

Thiem started the match at the ATP 250 grass court tournament strongly – breaking the world No. 42 to go up 4-2 shortly before the unfortunate end.

After receiving a medical timeout, the second seed decided he could not continue and indicated he sustained the injury while hitting a forehand.

It was the Austrian’s first ATP grass court match since 2019 – when he lost to Sam Querrey in the first round of Wimbledon.

The issue raises question marks over Thiem’s participation at this year’s Wimbledon – with The Championships set to start in less than a week.

Mannarino will face either Karen Khachanov or Feliciano Lopez in the quarter-finals.
