Stefanos Tsitsipas has been delighted with the backing he has received at the French Open as he continues his quest to better last year's semi-final run.

The 22 year-old has previously spoke of his fondness for Roland Garros, and he earned a tour-leading 35th win of the season against Pedro Martinez.

It finished 6-3 6-4 6-3 in the second round in favour of the fifth seed, who is yet to lose a set at this year's second grand slam.

Tsitsipas is leading the FedEX ATP Race to Turin, and John Isner stands in his way of a fourth-round place.

"I really like playing in Paris," said Tsitsipas, who won titles in Monte Carlo and Lyon before heading to Roland Garros.

"I feel like the fans have embraced me and made me one of them. So, I'm really glad my tennis is there, my performance is there, and I'm able to deliver not just good tennis but also create a good atmosphere on this court."

Tsitsipas, who at one point dropped his racket while serving, did have to work for his win, though. Martinez broke him in the first and second sets, and the Greek was then denied the opportunity to serve out the win in the third.

Martinez's stand did not last much longer – Tsitsipas' backhand winner in the following game sealing the win.

"I've had good weeks this year, I've had some good results, but, of course, I feel like there's always better," the world number five added.

"I don't see my performance so far as super-excellent and outstanding, but I've been consistent and that's very important."

MEDVEDEV BITES BACK

Daniil Medvedev might finally have settled into life at Roland Garros. The second seed had a dismal record in the French Open heading into this year's grand slam, but despite a shaky start, he defeated Tommy Paul 3-6 6-1 6-4 6-3 to claim a place in round three.

Though Paul made the most of a shaky opening set from Medvedev, the Russian rallied in set two and kept the momentum going, winning 80 per cent of his first-serve points in a victory which took two hours and 18 minutes to round off, and also included eight breaks of serve from the world number two.

Next up is Reilly Opelka, who saw off Jaume Munar. The American has a losing 2-1 head-to-head record against Medvedev, though this is the first time they will meet on clay.

There was a shock elsewhere, as 11th seed Roberto Bautista Agut was dumped out by Swiss qualifier Henri Laaksonen.

ZVEREV GETS SNAPPY AFTER RAGGED DISPLAY

World number six Alexander Zverev was made to work for his place in round three, as he overcame Roman Safiullin 7-6 (7-4) 6-3 7-6 (7-1).

Zverev trailed in both the second and third sets, as the 24-year-old needed two tie-breaks to beat the qualifier.

"Obviously, I don't do it on purpose," Zverev said. "I don't go into the match and say, 'Okay, my tactic is I'm going to be a break down, I'm going to fight back and come back'.

"That's not how it works. I'm a break down most of the time because I play unfocused games or the opponent plays well."

Zverev will play Laslo Djere in round three, and despite his frustration after the match, the German has moved onto 20 wins for the season, which already includes titles in Acapulco and Madrid.

Djere beat fellow Serbian Miomir Kecmanovic, and if Zverev should keep winning, he may well face a quarter-final against Casper Ruud, the promising Norwegian player who beat Kamil Majchrzak 6-3 6-2 6-4 to make it to the third round at Roland Garros for a third straight season.

Standing in the way of Ruud and the last eight is Alejandro Davidovich Fokina, who went the distance to defeat Botic Van De Zandschulp.
