The Austrian tennis professional Dominic Thiem is still waiting for success after his comeback on the ATP tour.
The 28-year-old lost his first-round match at the Masters in Madrid against British Andy Murray 3-6, 4-6.
The 2020 US Open champion had previously lost his opening matches at the tournaments in Belgrade and Estoril in Portugal.
Thiem had had to take a long break since June 2021 due to a complicated hand injury. At the end of March, Thiem played his first official match after the long break at the Challenger tournament in Marbella, but lost in two sets to the unknown Argentinian Pedro Cachin.
Then he was slowed down again by a coronavirus infection.
