Unheralded American Zachary Svajda continued his surprise French Open run on Saturday by posting a 6-3, 6-4, 3-6, 4-6, 6-3 victory over No. 25 Francisco Cerundolo to reach the fourth round in Paris.

Svajda committed 18 fewer unforced errors (59-41) than Cerundolo while thriving on the clay at Roland Garros.

The run is emotional for Svajda, whose father, Tom, died of cancer last October. Saturday would have been Tom's 61st birthday, and Svajda pointed to the sky after finishing off the victory.

'I was thinking about that,' Svajda said. 'I was nervous. I know he's proud of me, and I want to perform well and win. When I got that match, the last point, I just teared up, fell to the ground like, 'Oh my gosh, what is happening?''

Cerundolo of Argentina had the edge in aces (13-10) and winners (61-43), while Svajda scored well by converting 6 of 9 break points.

Svajda will next face No. 10 Flavio Cobolli, who sailed to a 6-2, 6-2, 6-3 victory over Learner Tien.

Due to a slew of upsets, Cobolli is the third-highest-seeded player remaining in the field. The Italian is also aware that not a single former champion remains in the field.

'Of course I want to think match by match,' Cobolli said. 'That's the way that I want to think this week.'

'I know that there are many possibilities to have a new Grand Slam champion. For sure, we will have a new Grand Slam champion, but I don't want to think about this. For sure, I have now another tough match.'

Argentina's Juan Manuel Cerundolo, who upset top-seeded Jannik Sinner of Italy on Thursday, needed five hours and 57 minutes to finish off a 6-4, 6-7 (7), 7-6 (4), 6-7 (4), 7-6 (6) victory over Spain's Martin Landaluce. The match was the third-longest in Roland Garros history.

Juan Manuel Cerundolo won 214 points to Landaluce's 213 and held a 16-6 edge in aces. Landaluce had more winners (87-76) and also committed more unforced errors (86-71).

Italy's Matteo Berrettini also won a lengthy match with a marathon fifth-set tiebreaker, outlasting Argentina's Francisco Comesana 7-6 (3), 5-7, 6-7 (4), 6-4, 7-6 (13) in five hours and 13 minutes.

'Francisco played an unbelievable match,' said Berrettini, who lost in the 2021 Wimbledon final. 'It was an unbelievable match, I really had to find my way (through) and I gave it everything I had.'

Berrettini will face Juan Manuel Cerundolo in the round of 16.

Chile's Alejandro Tabilo moved on with a 4-6, 6-3, 6-4, 7-6 (9) victory over 17-year-old Moise Kouame of France.

Also, Italy's Matteo Arnaldi outlasted Belgium's Raphael Collignon 6-4, 6-7 (5), 5-7, 6-4, 7-6 (8).
