Fourth-seeded Stefanos Tsitsipas easily dispatched Lucas Pouille of France 6-3, 6-4. The Greek posted seven aces and won 94 per cent of his first serves.
"It was good magic, a fair amount of magic dust," Tsitsipas said. "A great start at the beginning of this tournament."
He has become the first man to win 25 matches this year.
Tsitsipas is 8-1 on clay in 2022, which includes his run to the Masters 1000 title in Monte Carlo.

6:30 PM EEST (Greece)
