Tsitsipas has been in good form heading into Roland Garros, reaching the final of the Madrid Open following victories over fourth seed Alexander Zverev and five-time champion Rafael Nadal.
He also captured his third ATP title - and his first on clay - when he beat Uruguay's Pablo Cuevas 6-3 7-6 (7-4) to win the Estoril Open before losing in the semi-finals to Nadal in Rome.
The Greek, who is the rising star on the ATP Tour, also played in clay tournaments in Monte Carlo and Barcelona - winning 13 matches in total on clay before coming to Paris.
"It is quite different to other tournaments I have played. It is slow. It is not too fast, it is fine. I love playing on this court though. It gives you another energy on the big arenas," said Tsitsipas following his win over Marterer.
"These are the moments that we are practising and dreaming of."
