Stefanos Tsitsipas defeated Dominic Thiem in the final, 6–7^(6–8), 6–2, 7–6^(7–4) to win the singles tennis title at the 2019 ATP Finals. Tsitsipas was making his tournament debut. It marked the first instance since 2005, and only the fourth instance overall, that the Tour Finals champion was determined via a final-set tiebreak.^{[citation needed]}
