Top-seeded Carlos Alcaraz has won his first-round match at the Hamburg Open while Emil Ruusuvuori had an upset victory over Diego Schwartzman.
The 19-year-old Alcaraz dropped the opening set but recovered to win 3-6 6-1 7-6 (7-3) against 259th-ranked German wildcard Nicola Kuhn on Tuesday.
The Spaniard's next assignment is a second-round meeting with Filip Krajinovic after the Serbian saved two match points before prevailing 6-1 4-6 7-6 (8-6) against Sebastian Baez of Argentina.
Should Alcaraz reach the final in Germany this week, he will move to a career-high No.5 in the world next Monday. If he wins his fifth ATP Tour title of the year, he will rise to No.4.
"It was tough. I mean, the first round in every tournament is tough," Alcaraz, who was playing his first match since his run to the fourth round at Wimbledon, said.
"I came from the grass, and the difference was too much. I'm really happy to be [through to] the second round. I'm sure that I will be better in the next round, but I'm really happy with the win."
Finland's Ruusuvuori won 7-5 6-4 against third-seeded Schwartzman, who was coming off a 6-1 6-0 loss in his previous match against Pablo Carreno Busta of Spain last week in Bastad.
Fourth seed Carreno Busta's good form continued with a 6-2 6-1 success over Italian qualifier Luca Nardi.
The sixth and eighth seeds though are out.
Georgia's Nikoloz Basilashvili was beaten 6-4 6-0 by Russia's Aslan Karatsev and Dane Holger Rune lost 7-6 (8-6) 7-5 to Dutchman Tallon Griekspoor.
