The 20-year-old has enjoyed an eye-catching clay season thus far, reaching the final in Madrid and the semi-final in Rome and came through against the German 6-2, 6-2, 7-6(4). As the scoreline would suggest, it was in the first two sets that Tsitsipas played his most eye-catching tennis, freely coming to the net and keeping Marterer at arm's length throughout. After missing a chance to repeat the trick in the opening game of the second set, he moved ahead in the third and again broke in the penultimate one and holding his nerve on serve. "Very satisfied.

"I stayed mentally strong and closed the tie-break at the end.вЂќ Tsitsipas has been touted as a potential challenger for the Roland Garros title, having beaten 11-time champion Rafael Nadal during his final run in Madrid.
