British number one Kyle Edmund fought back from a set down to reach the second round of the China Open with victory over Peter Gojowczyk.
Fifth seed Edmund won 3-6 6-1 6-2 in 91 minutes in Beijing against the world number 70 from Germany.
Edmund will face Italian qualifier Matteo Berrettini or Argentina's Leonardo Mayer next.
The world number 16 is playing his first competitive event since his US Open first-round loss in August.
The 23-year-old has had a tough year because of illness, including recurring bouts of tonsillitis.
Before heading to China, he helped Team Europe beat Team World in the Laver Cup exhibition event in Chicago at the end of September.
