Top two seeds look strong to reach final eight

Medvedev was solid in a 6-2, 6-4 victory over Egor Gerasimov. A week after losing in the first round in Rotterdam, the Russian won 65 percent of his second serve points and saved the only break point he faced in the 71-minute victory.

"I think Egor is always a good player on indoor hard courts", he said after the match. "I actually think it was not his best match, especially at the beginning of the first set. He was doing some mistakes, I took advantage of it. I feel like I was playing well."

Tsitsipas broke the serve of Lucas Pouille four times as he got his quest for a third straight Marseille title off to a good start with a 6-2, 6-3 victory over the Frenchman.

"I figured out the tactics early on and brought the top of my game", he said after the 64-minute win. "I've been playing well, i've been feeling good on court. [I'm] just trying to stay humble, it doesn't matter where I stand in the ATP rankings."
