A resurgent Daniil Medvedev claimed his first title for 882 days with victory over Corentin Moutet in the Almaty Open final.
The Russian former world number one has had a torrid year, winning just one match at the Grand Slams and suffering a meltdown at the US Open.
Medvedev's inconsistency on the ATP Tour - and struggles with his serve in particular - led to him dropping out of the world's top 10 and ultimately splitting with long-time coach Gilles Cervara.
Now working with Thomas Johansson and Rohan Goetzke, Medvedev has steadily improved in the past month - culminating in a hard-fought 7-5 4-6 6-3 victory over Frenchman Moutet.
