Top seed Dominic Thiem claimed his 16th career title and fifth of 2019 on Sunday with a 3-6, 6-4, 6-3 comeback win over Argentina's Diego Schwartzman in the Vienna ATP final.
The 26-year-old Austrian delighted a packed home crowd in a victory stretched over two hours and 25 minutes.
Thiem improved to 9-0 in his home country this year, having also lifted the Kitzbuhel trophy in August without dropping a set.
World number five Thiem is the first player to lift five tour-level trophies in 2019, breaking a five-way tie with Novak Djokovic, Rafael Nadal, Roger Federer and Daniil Medvedev.
The Roland Garros runner-up added Vienna to Kitzbuhel, Beijing, Barcelona and Indian Wells.
