It may be opening day at Roland-Garros but the Greek already has a second-week look in his eyes.
He ran out a 7-6(6), 6-3, 6-1 victory over the 58th-ranked Frenchman, played in front of an empty Court Philippe-Chatrier due to the 9pm pandemic curfew in Paris.
"For sure concentration is an important element in my game," he said on court of his laser focus. "I was able to increase my level of concentration today after the first set. I felt like I put my foot on the gas and didn't let go."
Before the tournament commenced the 22-year-old confessed to reporters that he would like to be the surprise of the tournament. On Sunday he seemed more concerned with avoiding surprises, as he seized every opportunity to distance himself from the dangerous Chardy.
Tsitsipas overcame a wobble in the opening set, rallying from 4-1 down in the tie-break to close. It was not museum-worthy tennis, but the Greek's ability to stay steady until his chance presented itself could serve him well over the coming fortnight.
