Марко Трунгеллити

2012: ATP debut

Trungelliti made his ATP Tour debut at the 2012 Croatian Open where he advanced through the 3 qualifying rounds by defeating Juan-Martín Aranguren 6–3, 6–2, Jose Anton Salazar Martin 7–6⁽⁴⁾, 6–3 and Adrián Menéndez Maceiras 6–3, 6–2 to make his first appearance in a main draw. In the first round, he would go on to defeat Paolo Lorenzi 7–5, 6–4 before losing in the second round to Carlos Berlocq 6–7⁽⁴⁾, 6–4, 1–6.

2016-2018: Major & Masters debuts, first wins, including a top-10 win

In 2016, he qualified for two consecutive Grand Slams for the first time in his career at the 2016 Australian Open and at the 2016 French Open. He reached the second round in both Grand Slams, beating Jozef Kovalík on the hard courts of the first major of the season, and achieving his first and only victory against a top player, defeating 10th seed Marin Cilic, on the Parisian clay. Between January and May, more precisely during March 2016, he achieved his only entry into a Masters 1000, also via the qualifying stage, in 2016 BNP Paribas Open.

At the 2018 French Open Trungelliti drove for 10 hours from Barcelona to Paris to be a late replacement for the injured Nick Kyrgios who had been due to face his compatriot Bernard Tomic. He only arrived to sign in shortly before midnight, and the match was scheduled first on court the following morning. Despite this Trungelliti defeated Tomic in four sets to make the second round at Roland Garros. He had been joined in his car journey by his mother and 89-year-old grandmother who had happened to have been visiting from Argentina at the time. He lost to Marco Cecchinato in the second round.

2021–2024: Wimbledon debut and maiden US Open win

Between June 2021 and January 2022, he qualified for three consecutive Grand Slams for the first time in his career at the 2021 Wimbledon Championships, the 2021 US Open and at the 2022 Australian Open. He became the only Argentine to qualify at the All England Club and the only South American to qualify at the US Open in 2021. The Argentine saved six match points to defeat American Aleksander Kovacevic in the final round of qualifying at the US Open, to make just his eight main draw appearance at a Major. He defeated 29th seed Alejandro Davidovich Fokina in the first round to reach the second round for the first time at this Major before losing to fellow Argentine Facundo Bagnis.

At the 2022 Australian Open he qualified again but lost in the first round in a five set match against Frances Tiafoe.

Ranked No. 197, he qualified for the ATP 500 2024 Barcelona Open Banc Sabadell and reached the round of 16, defeating qualifier Duje Ajdukovic and upsetting ninth seed Nicolás Jarry.
