Thiem played really solid at the US Open, which isn't a huge surprise considering that he actually won that event in the past. Even in that match against Shelton, Thiem had the upper hand for much of the opening set before the American pulled away in the tie-break.
Stomach issues prevented the Austrian from continuing and they actually plagued him for a very long time after the event as he battled the issue for two weeks before he resumed practice.
It was a long story with my stomach. After the US Open, I couldn't do anything for two weeks before I could start training again. But now I'm fine again. All I know is that it wasn't bacteria. Maybe I got some bad water or food somewhere. I love spicy food, maybe I had too much of it.
His first match in Vienna is a complicated one as he's going to play against Stefanos Tsitsipas. They had some nice battles this year, matches that were pretty close.
Thiem admitted that Tsitsipas is the favourite, but he's going to try and win, especially in front of the home crowd in Vienna, which will certainly cheer him on.
He's the favorite for sure, but if I bring my performance to the court, I'm sure I'll have chances. The last duels were all very close and were only decided in the tiebreak of the last set. Especially indoors, often only a few points decide.
In the first years here, that might have inhibited me a little. Now it's no longer like that, especially since I was able to win the tournament in 2019. I'm looking forward to that positive energy, which is incredibly helpful for me.
