Dominic Thiem

Dominic Thiem (German pronunciation: [ˈdɔmɪnɪk ˈtiːm]; born 3 September 1993) is an Austrian former professional tennis player. He was ranked world No. 3 in singles by the ATP, achieved in March 2020. Thiem won 17 ATP Tour-level singles titles, including the 2020 US Open. He was also runner-up at three other majors (the 2018 and 2019 French Opens, and at the 2020 Australian Open), and at the 2019 and 2020 ATP Finals.

As a junior, Thiem was ranked as high as world No. 2. He was runner-up at the 2011 French Open boys tournament, and won the 2011 Orange Bowl. As a professional, he broke into the top 100 for the first time in 2014. In 2015, he won his first ATP title at the 2015 Open de Nice Côte d'Azur. He reached his first major semifinal at the 2016 French Open. In doing so, he first entered the top ten in the ATP rankings. He went on to reach his first Masters 1000 final in 2017 at the Madrid Open, then reaching his first major final the next year.

Thiem won a Masters 1000 title at the 2019 Indian Wells Masters, beating Roger Federer in the final, before going on to reach three more major finals, winning the last at the 2020 US Open. With that win, Thiem became the first man born in the 1990s to claim a major singles title, as well as the first Austrian to win the US Open singles title. In 2021, Thiem suffered a wrist injury from which he never fully recovered, ultimately retiring from the sport following the 2024 Vienna Open.

Thiem had some of the heaviest groundstrokes of the tour, consistently hitting big with both his forehand and single-handed backhand. Generally thought of as a baseliner, he added more variety with the use of a sliced backhand and more netplay after adding coach Aaron Wirth to his team in March 2019. At 1.85 m (6 ft 1 in), he possessed a serve reaching up to 145 miles per hour (233 km/h), which he often used to set up effective one-two punches. Through the end of 2025, Thiem remains the last one-handed backhand player to win a singles major. Thiem won the 2020 Austrian Sportsman of the Year award, the fourth time a tennis player has won the award since its creation in 1949.

Early life and background

Thiem was born in Wiener Neustadt, Austria, on 3 September 1993 to Wolfgang and Karin Thiem, both of whom are tennis coaches. He has a younger brother, Moritz Thiem, who is also a professional tennis player. Thiem grew up in Lichtenwörth and began playing tennis when he was six years old.

Thiem's father, Wolfgang, began working as a coach at Günter Bresnik's academy in Vienna in 1997, when Thiem was just three years old. Bresnik became Thiem's coach formally from age nine. It was Bresnik who advised the change of Thiem's two-handed backhand to a one-handed backhand when he was 12 years old. Bresnik has said that Thiem's junior results took a dip for about a year while the stroke developed. Thiem struggled with health issues when he was 17 years old, which he attributed to a large growth spurt of 16 centimetres (6 in) he had that year.

Junior career

Thiem entered his first event on the International Tennis Federation (ITF) junior circuit in early 2008 when he was 14. Thiem reached an ITF Junior Circuit ranking of world No. 2 (combined singles and doubles) on 3 January 2011. He did not play many events in 2008, returning with a fuller schedule in 2009. He won his first junior title at the Preveza Cup, a Grade 5 tournament held on hard court in Greece. Thiem followed this with another title in 2009 at the Grawe Junior Cup, a slightly higher level Grade 4 tournament, on clay in Croatia.

In 2010 Thiem won his first Grade 1 tournament on clay at the Country Club Barranquilla Open, in Colombia, without dropping a set. He followed this with a title in Peru at the Grade 2 Inka Bowl and another Grade 1 title at the 32nd Torneo Internazionale "Citta' Di Santa Croce" Mauro Sabatini in Italy. He was seeded eighth at the 2010 French Open Junior Championships but lost in the first round to Ashley Hewitt. He also lost in the first round of the US Open Junior Championships before winning the XXIV Yucatan World Cup 2010 and the Eddie Herr International Junior Tennis Championships back to back.

Thiem reached the second round at the Australian Open Junior Championships in early 2011. In May he reached the final of the 2011 French Open boys' event losing a close final to Bjorn Fratangelo, in three sets. He won the next tournament he played, the 12th Gerry Weber Junior Open, a Grade 2 tournament held on grass. He lost in the third round of the Junior Championships, Wimbledon, and in the first round at the 2011 US Open Junior Championships. Thiem completed his junior career by winning his last three singles tournaments, the XXV Yucatan Cup, the Eddie Herr International Junior Tennis Championships and culminating in taking the title at the Orange Bowl International Tennis Championship in Plantation, Florida, United States.

Thiem finished his junior career with a 115–33 win–loss record in singles and 49–32 win–loss record in doubles. He recorded victories over many future stars such as Lucas Pouille and Kyle Edmund.

Thiem started his campaign at the French Open by beating Frenchman Paul-Henri Mathieu in straight sets. In the second round he faced world No. 1 and the defending champion, Rafael Nadal, but was defeated in straight sets, only winning seven games in the process. Thiem suffered consecutive first-round losses on grass at the Queen's Club Championships in London, to David Goffin, and at the Wimbledon Championships to Australian qualifier Luke Saville.
