Lucas Miedler Bio
Lucas Miedler is an Austrian professional tennis player born on 21 June 1996 in Tulln, Austria. Standing 1.80 m (5 ft 11 in) tall, he plays right-handed with a one-handed backhand and turned professional in 2014. Miedler is best known for his work on the doubles circuit, where he has built a career-high ATP ranking of world No. 23, achieved on 10 November 2025, and has collected 11 ATP Tour doubles titles, including seven alongside compatriot Alexander Erler.
While his singles results have been limited, with a career-high singles ranking of No. 201 in October 2018, Miedler has become a respected figure in Austrian tennis through consistent doubles performances at home tournaments and on the international stage. He continues to be coached by Wolfgang Thiem and remains based in his hometown of Tulln.
Early Life and Background
Lucas Miedler was born and raised in Tulln, a small city in Lower Austria. From an early age, he gravitated toward tennis, developing his game on the local courts and eventually joining the regional junior development system. His right-handed playing style, featuring a one-handed backhand, was shaped during these formative years and would later become a recognizable part of his identity on the professional tour.
As a junior, Miedler showed enough promise to represent Austria in international age-group competitions. In 2014, he partnered with Australian player Bradley Mousley to win the boys’ doubles title at the 2014 Australian Open, defeating the French duo of Quentin Halys and Johan-Sébastien Tatlot 6-3, 7-6(7-3). That Grand Slam triumph at the junior level served as a springboard toward his transition to the professional ranks later that same year.
Path to Tennis
Following his junior success in Melbourne, Miedler committed to the professional circuit in 2014, beginning with appearances on the ITF Futures and ATP Challenger circuits. His early focus was on building match experience and improving his physical conditioning, with the support of coach Wolfgang Thiem, who has remained a steady presence in his career.
By 2015, Miedler had progressed enough to make his ATP World Tour main draw debut at the Vienna Open, where he qualified for the first round and faced Latvian Ernests Gulbis. Although he lost that match in three sets, the appearance marked his entry into top-level professional tennis and signaled the start of a steady rise through the doubles rankings over the following years.

He reached a career-high singles ranking of No. 201 on 15 October 2018, a milestone that reflected his competitive level but also hinted that doubles would be his stronger suit going forward.
During this period, Miedler began partnering with Alexander Erler, an alliance that would later produce significant results. The pair worked on their communication and net play, gradually building the foundation for the success they would enjoy at home tournaments and on the ATP 500 circuit.

Miedler captured his maiden ATP Tour doubles title at the 2021 Generali Open Kitzbühel, partnering with Alexander Erler. The victory on home soil gave him his first taste of ATP-level success and helped lift his doubles ranking into the top 100.
In 2022, the Austrian duo of Erler and Miedler won their biggest title to date at the ATP 500 Erste Bank Open in Vienna, claiming the trophy without dropping a set. The performance propelled Miedler further up the rankings and established him as a regular presence in ATP doubles events.
