## Professional career
### 2021: First ATP doubles title and top 100 debut

Zieliński made his top 100 doubles debut at No. 99 on 1 November 2021 after winning his first ATP Tour doubles title at the 2021 Moselle Open with his compatriot Hubert Hurkacz.

### 2022: First Major quarterfinal, second ATP title and top 35 debut

In January 2022, he made his debut participating as part of the Polish team at the 2022 ATP Cup, where he played doubles with Szymon Walków and won against Georgia and Argentina. After Hurkacz's win over Diego Schwartzman sealed the victory for Poland over Argentina, the Polish team advanced to the semifinals. The pair won again against Spain in doubles, but the team did not advance to the finals.
He reached the top 50 in doubles at world No. 49 on 18 July 2022. In August, at his debut at a Masters 1000 level, he reached his first semifinal at the 2022 National Bank Open also with Hurkacz, defeating sixth seeds Puetz/Venus in the first round, Bopanna/Middelkoop in the second and fourth seeds, and French Open champions Arévalo/Rogers in the quarterfinals.
At the US Open, he reached the quarterfinals of a Grand Slam for the first time in his career with partner Hugo Nys, defeating 10th seeded pair Jamie Murray/Bruno Soares and Ariel Behar/Gonzalo Escobar. As a result, he made his top 40 debut in the rankings. The pair won their first title at the 2022 Moselle Open.

### 2023: Major final and Masters doubles title, World No. 7

At the 2023 Australian Open, he achieved his career best Grand Slam result by advancing to the semifinals with partner Hugo Nys. The pair defeated Rafael Matos/David Vega Hernández, Max Purcell/Jordan Thompson, second seeds Rajeev Ram/Joe Salisbury and Benjamin Bonzi/Arthur Rinderknech in the quarterfinals. The pair beat the French duo of Jérémy Chardy/Fabrice Martin in the semifinals to advance to their first Grand Slam final, where they lost to Australians Rinky Hijikata and Jason Kubler.
Following their first Masters 1000 title in Rome, Zielinski reached a career high ranking of No. 12 on 22 May 2023. Following the 2023 French Open, he made his debut in the top 10 in the rankings at world No. 9 on 12 June 2023.
At the 2023 Moselle Open in Metz the Monegasque/Polish pair defended their crown but came short of qualifying for the year-end 2023 ATP Finals, finishing ninth in the ATP race.

### 2024: First Polish mixed doubles champion in Australia and at Wimbledon

At the 2024 Australian Open he reached the quarterfinals with Nys but they lost to the unseeded pair Dominik Koepfer and Yannick Hanfmann and could not defend their runner-up points from the previous year. Despite the loss in the doubles event, seeded third, he reached the final in the mixed doubles partnering Hsieh Su-wei, and they won their first Major mixed doubles title, defeating second seeds Desirae Krawczyk and Neal Skupski. They saved a championship point en route to Zieliński's first Grand Slam title and Hsieh's seventh, and first on hardcourts. Zieliński became the first Polish finalist and champion at a mixed doubles event.
At the 2024 Abierto Mexicano Telcel in Acapulco he won his first ATP 500 title with Nys defeating top pair of Santiago Gonzalez and Neal Skupski.
He reached the mixed doubles semifinals at the 2024 French Open with Hsieh Su-wei where they lost to Krawczyk and Skupski. At the next Grand Slam, the 2024 Wimbledon Championships, he reached another final in mixed doubles with the same partner, Hsieh Su-wei. They won the title defeating Mexican duo Giuliana Olmos and Santiago González in the final.
