Winston-Salem (North Carolina) – Dominic Thiem has made noticeable progress in recent weeks on the long way back to the top of the tennis world. The training went well, said the Lower Austrian, who is currently 231st in the world rankings, on Sunday. “I tried to get back on the level. I did quite well.” Most recently, however, a respiratory infection with a cold and cough put the 28-year-old out of action for a week.
