A shot at revenge is on the cards next when he faces Chinese teenager Jerry Shang in a rematch of their Australian Open first-round qualifying showdown.
“That was my first Grand Slam, so it's not easy,” he said. “He's a young guy, lefty, he's playing so good. It's much different though, this is clay. I think it's not an easy match for sure.”
Also contesting just his second Grand Slam qualifying campaign, Shang registered a 6-3, 6-4 win over Uruguayan former top-20 player Pablo Cuevas.
The 18-year-old might not have spent as many of his formative years as Marozsan honing his game on clay, but the world No.200 has rapidly found his feet.
“Now I really like it and the Paris clay is one of the fastest,” he said. “Without bad bounces, it's great tennis for me.”
Shang’s great tennis was in the spotlight at Melbourne Park in January when as a qualifier he became the first Chinese man to win a Grand Slam main draw match against Oscar Otte before falling to Frances Tiafoe.
