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.
Edmund was broken in his first service game against Gojowczyk, falling 3-0 behind following several unforced errors, before responding to get the set back on serve at 3-2.
But Gojowczyk broke again for a 5-3 lead, eventually converting his first set point with an ace after 31 minutes.
Edmund, though, broke the German three times in the second to force a decider after converting the second of three set points with an ace.
The Briton claimed the key break for a 3-2 lead in the third set before pulling clear to seal victory at the first opportunity with an ace.
