This also applies to the serve. A look at the statistics of recent years shows: Thiem has never beaten so few aces as this year. He averages 3.2 per game. The best value dates from 2020, when it was around 7.18. After all, the double fault rate is limited, Thiem is around 1.8 per game. The first service in particular lets Thiem down too often: 69 percent points gained mark a career low point, in the last 10 years this value has always been over 70 percent (high point in 2018 with 76 percent).
