Nonetheless, tennis was still only his third priority, behind skiing and football.{{cite web |title=Five Things To Know About Jannik Sinner |url=https://www.atptour.com/en/news/five-things-to-know-jannik-sinner |website=ATP Tour |access-date=15 November 2020 |date=23 May 2020 |archive-date=19 January 2021 |archive-url=https://web.archive.org/web/20210119062000/https://www.atptour.com/en/news/five-things-to-know-jannik-sinner |url-status=live }}{{cite web |title=First-Time Winner Spotlight: Jannik Sinner |url=https://www.atptour.com/en/news/sinner-first-time-winner-spotlight-sofia-2020 |website=ATP Tour |access-date=15 November 2020 |date=14 November 2020 |archive-date=2 March 2021 |archive-url=https://web.archive.org/web/20210302174929/https://www.atptour.com/en/news/sinner-first-time-winner-spotlight-sofia-2020 |url-status=live }} In the mornings he competed in ski races and in the afternoons he played football matches for AFC Sexten (Youth).

At age 13, Sinner gave up skiing and football in favour of tennis due to his physique; he was tall, thin, and weighed only 35 kilograms. He also preferred competing in an individual sport directly against an opponent and having more control over the outcome.{{Cite web |last=Aguire |first=Abby |date=2024-04-04 |title=The Stunning Rise of Tennis's Jannik Sinner |url=https://www.vogue.com/article/profile-jannik-sinner-june-2024 |access-date=2024-06-27 |website=Vogue |language=en-US |archive-date=27 June 2024 |archive-url=https://web.archive.org/web/20240627191926/https://www.vogue.com/article/profile-jannik-sinner-june-2024 |url-status=live }} He moved on his own to Bordighera in Liguria, on the Italian Riviera, to train at the Piatti Tennis Center under Riccardo Piatti and Massimo Sartori, a decision his parents supported. There, Sinner lived with the family of Luka Cvjetković, one of his coaches, and later moved out to share an apartment with two boys.{{cite web |last=Rossingh |first=Danielle |title=Jannik Sinner: Ski champ to tennis star |url=https://www.rolandgarros.com/en-us/article/jannik-sinner-interview-rg2020-ski-champ-tennis-star |website=Roland Garros |access-date=15 November 2020 |date=29 September 2020 |archive-date=28 November 2020 |archive-url=https://web.archive.org/web/20201128112701/https://www.rolandgarros.com/en-us/article/jannik-sinner-interview-rg2020-ski-champ-tennis-star |url-status=live }} Before he began training in tennis full-time with Piatti, he had been playing only twice a week. He graduated from the Walther Institute, a private economics school in Bolzano.

Sinner began playing tennis on the ITF Junior Circuit. In spite of having limited success as a junior, he moved mainly to the professional tour following the end of 2017. He never played the main draw of any high-level Grade 1 events in singles, and the only higher-level Grade A tournament he entered was the Trofeo Bonfiglio.

Sinner followed up an opening round loss at Italy's Grade A tournament in 2017 with a quarterfinal in 2018. That was the only junior event he played in 2018. He never played any of the junior Grand Slam tournaments. Because he entered so few high-level tournaments, Sinner's career-high junior ranking was a relatively low No. 133.{{cite web |title=Jannik Sinner Juniors Singles Activity |url=https://www.itftennis.com/en/players/jannik-sinner/800405198/ita/jt/s/activity/#pprofile-info-tabs |website=ITF Tennis |access-date=15 November 2020 |archive-date=25 January 2021 |archive-url=https://web.archive.org/web/20210125105300/https://www.itftennis.com/en/players/jannik-sinner/800405198/ita/jt/s/activity/#pprofile-info-tabs |url-status=live }}

Sinner began playing on the ITF Men's Circuit in early 2018. With his low ranking he could initially be directly accepted into only ITF Futures events. Nonetheless, he began receiving wild cards for ATP Challenger Tour events, the second-tier tour run by the Association of Tennis Professionals (ATP), in the second half of the year.{{cite web |title=Jannik Sinner Men's Singles Activity |url=https://www.itftennis.com/en/players/jannik-sinner/800405198/ita/mt/s/activity/ |website=ITF Tennis |access-date=15 November 2020 |archive-date=16 November 2020 |archive-url=https://web.archive.org/web/20201116165816/https://www.itftennis.com/en/players/jannik-sinner/800405198/ita/mt/s/activity/ |url-status=live }} His only ITF title of the year was in doubles,{{cite web |title=Jannik Sinner Men's Doubles Activity |url=https://www.itftennis.com/en/players/jannik-sinner/800405198/ita/mt/d/activity/ |website=ITF Tennis |access-date=15 November 2020 |archive-date=16 November 2020 |archive-url=https://web.archive.org/web/20201116200742/https://www.itftennis.com/en/players/jannik-sinner/800405198/ita/mt/d/activity/ |url-status=live }} and he finished the season ranked No. 551.{{cite web |title=Jannik Sinner Rankings History |url=https://www.atptour.com/en/players/jannik-sinner/s0ag/rankings-history |website=ATP Tour |access-date=15 November 2020 |archive-date=14 October 2020 |archive-url=https://web.archive.org/web/20201014014927/https://www.atptour.com/en/players/jannik-sinner/s0ag/rankings-history |url-status=live }}

Sinner won his first ATP Challenger title in Bergamo in February 2019 at the age of 17 years and 6 months, despite entering the tournament with no match wins at the Challenger level. He became the first person born in 2001 to reach a Challenger final, and the youngest Italian to win a Challenger title in history. With the title, he rose over 200 spots in ATP rankings up to No. 324.{{cite web|url=http://www.tennis-tourtalk.com/40599/sinner-sweeps-into-bergamo-challenger-final|title=Sinner Sweeps Into Bergamo Challenger Final|date=23 February 2019|access-date=23 February 2019|website=Tennis TourTalk|archive-date=20 January 2021|archive-url=https://web.archive.org/web/20210120013948/https://www.tennis-tourtalk.com/40599/sinner-sweeps-into-bergamo-challenger-final|url-status=live}}{{cite web | url = https://www.atptour.com/en/news/bergamo-challenger-2019-sinner | title = Sinner's Stunner: 17-Year-Old Reflects On Maiden Title | website = ATP Tour | date = 26 February 2019 | access-date = 26 February 2019 | last = Meiseles | first = Josh | archive-date = 27 July 2019 | archive-url = https://web.archive.org/web/20190727130402/https://www.atptour.com/en/news/bergamo-challenger-2019-sinner | url-status = live }}
