The third seed, who is making his debut at the ATP 500 event, overpowered Kukushkin as he quickly found his range on the hard courts in Astana. He stepped inside the baseline to strike his forehand through the court and looked comfortable at the net, closing out points efficiently to advance after 83 minutes.
Tsitsipas has now earned 50 tour-level wins this year, lifting titles in Monte Carlo and Mallorca. The Greek has also improved his ATP Head2Head series against the 34-year-old to 4-0 and will next meet Italian qualifier Luca Nardi after the #NextGenATP star defeated qualifier Alexander Shevchenko 7-6(4), 6-2.
In earlier action, Karen Khachanov made a winning return to Tour when he defeated American Maxime Cressy 6-4, 7-6(3).
The World No. 18 was competing for the first time since he reached the semi-finals at the US Open last month, but showed little sign of rustiness to triumph after one hour and 31 minutes. Khachanov will face Marin Cilic or Oscar Otte in the second round.
Lucky loser Pavel Kotov downed Spaniard Alejandro Davidovich Fokina 6-4, 6-4 to book his spot in the second round. The 23-year-old will next play Roberto Bautista Agut.
