Speaking in his on-court interview after Friday's victory, the 28-year-old expressed sheer delight at his recent performances and said that he will enter the match against Berrettini with a 'free' mindset.“Tomorrow I can go into the match free, trying to do my best," said Thiem. "When I travelled to Bastad last week I didn’t expect to reach the quarter-finals there and then the semi-finals here. It is really, really good and I am happy with the progress."While he was happy with his overall performance in the Swiss Open quarterfinals, Thiem admitted that nerves played a part in the match, with the prospect of reaching his first ATP semifinal in over a year."Some things I didn’t like that much. I failed to serve out at [5-2], but it was also the nerves a little bit because it is my first semi-final in one and a half years. I need the points to go back up the rankings. I was happy I was able to break the nerves," he explained.Thiem will aim to climb as high as possible in the rankings before the start of the US Open on August 29, hoping to avoid facing some of the top title contenders in the early rounds. The 2022 US Open will be his first appearance at the New York Grand Slam since winning the 2020 final against Alexander Zverev.
