Welcome to the French Open briefing, where The Athletic\u00a0will explain the stories behind the stories on each day of the tournament.<\/p>\n

On Day 8, electronic line calling overshadowed a stunning match, two compatriots set up an intriguing match and a favorite began to reckon with pressure.<\/p>\n

Was Casper Ruud robbed of the second set against Jo\u00e3o Fonseca?<\/p>\n

At a hinge moment during two-time French Open finalist Casper Ruud\u2019s fourth-round match against Jo\u00e3o Fonseca, controversy erupted.<\/p>\n

Ruud, trailing by one set to love, was leading the second-set tiebreak 8-7 when Fonseca laced a forehand down the line. The line judge checking the baseline indicated that the ball was in, but a shout from the crowd said out. In the confusion, chair umpire Louise Engzell came down to inspect the mark.<\/p>\n

She ruled that the ball trace had caught the line. Ruud did not challenge the call but asked who had made it. On television coverage, an electronic line calling (ELC) replay came to the opposite conclusion.<\/p>\n

By now, everyone is well aware that the French Open breaks ranks with the three other Grand Slams, as well as ATP and WTA tour events, by relying on humans to call lines. Umpires and players have been getting in time-consuming spats all week: One player showed an umpire two different ball marks<\/a> during a match. A different player threatened to never speak to an umpire again<\/a>.<\/p>\n

Had Roland Garros not made its choice, Ruud would have knotted the match at 1-1. Instead \u2014 after a shot of his own was called out and overruled by Engzell as in, with which the ELC concurred \u2014 Fonseca took the tiebreak, and a two-set lead.<\/p>\n

The 19-year-old Brazilian never relinquished it, defeating Ruud 7-5, 7-6(8), 5-7, 6-2 to move into his first Grand Slam quarterfinal.<\/p>\n

The French Open\u2019s decision means that players, fans and commentators go from understanding in- and out-calls one way \u2014 electronic line calling \u2014 to another way \u2014 ball marks. Worse, those two ways of seeing can contradict each other.<\/p>\n

Because clay is a live surface<\/a>, where elements such as wind and uneven amounts of red brick dust on different parts of the court affect how a ball leaves its mark, it\u2019s not uncommon for a ball that lands in to leave a mark that looks out, and vice versa. ELC, which tracks trajectory and contact point, can \u201csee\u201d this and include that information in its final read-out. It also has a 3mm margin for error.<\/p>\n

A human umpire coming down to check a mark cannot do this, and can only determine whether or not the trace of the ball in any way overlaps with, or touches the edge of, the line in question. But TV viewers at home see the ELC replay, which contains more information than the trace but is rendered in exactly the same way, encouraging a comparison which doesn\u2019t quite overlap.<\/p>\n

It was tricky for players to adjust to line calling when clay-court tournaments adopted it<\/a>, because they\u2019d spent their whole tennis lives using ball marks as the letter of the law. It\u2019s difficult for players to accept that their eyes have been deceiving them for their entire lives, then trust a new system immediately. The same is true of fans, and the apparent injustice toward Ruud caused widespread annoyance. Roland Garros has sown mistrust in its own tournament.<\/p>\n

What will an all-Ukrainian quarterfinal mean to its players?<\/p>\n

For all of the upsets at Roland Garros, at least one of the quarterfinal matchups in the women\u2019s draw makes complete sense. Elina Svitolina, this year\u2019s winner at the Italian Open, and Marta Kostyuk, this year\u2019s winner at the Madrid Open, will face off for just the third time.<\/p>\n

The head-to-head is knotted at 1-1.<\/p>\n

The match ensures that there will be a Ukrainian semifinalist in the women\u2019s tournament for the first time in the Open Era, which feels fitting for how strong of a presence Ukrainian women have had at this tournament.<\/p>\n

World No. 55 Yuliia Starodubtseva\u00a0<\/a>defeated No. 2 seed Elena Rybakina, of Kazakhstan, in the second round. World No. 65 Oleksandra Oliynykova<\/a> used her career-best run at a Grand Slam \u2014 she lost to the Russian Diana Shnaider in the third round \u2014 to advocate for Ukraine.<\/p>\n

Then there\u2019s Kostyuk and Svitolina. The pair shared a high five in the corridor beneath Court Philippe-Chatrier as No. 15 seed Kostyuk walked to the locker room after upsetting four-time champion Iga \u015awi\u0105tek<\/a>\u00a07-5, 6-1 to open play Sunday.<\/p>\n

Svitolina, the No. 7 seed, was on her way to beat Belinda Bencic 4-6, 6-4, 6-0.<\/p>\n

Beyond their Ukrainian connection, Tuesday\u2019s match will feature two of the best-performing women on clay this year. Kostyuk arrives with a 16-match win streak, forged by two titles for the 23-year-old: the WTA 250 Rouen Open in France and the WTA 1000, played just below the Grand Slam level, in Madrid.<\/p>\n

Kostyuk said Sunday that things started clicking on clay for her after she gave herself more space to be creative on the dirt and enjoy her tennis more.<\/p>\n

\u201cI\u2019m the most consistent I have ever been in my career,\u201d Kostyuk said in her news conference.<\/p>\n

Svitolina, meantime, has always had a good relationship with the clay \u2014 especially in Rome, where she\u2019s won the title three times. But the French Open has been a sore spot: It\u2019s the only major where she has never made the semifinals.<\/p>\n

How will Alexander Zverev respond to opportunity and pressure?<\/p>\n

Amid all the chaos, world No. 3 and men\u2019s tournament favorite Alexander Zverev continues to progress serenely.<\/p>\n

On Sunday, he eased past the lucky loser Jesper de Jong 7-6(3), 6-4, 6-1 in two hours and 16 minutes. Compared to the marathons many of his colleagues have been enduring, it was more like a weekend stroll.<\/p>\n

Zverev is about to embark on possibly the biggest week of his professional career. He has played three Grand Slam finals, losing all three, but this is the first major where he has been the tournament favorite \u2014 a status afforded to him thanks to the absence of Carlos Alcaraz, and the early exits of Jannik Sinner and Novak Djokovic.<\/p>\n

With opportunity comes pressure. It\u2019s one thing to reach a final as a big underdog; it\u2019s another thing entirely to have the chance to walk through an open door, the kind which may not open again while Zverev is still in his prime.<\/p>\n

The 29-year-old German is aware of his shortcomings, and has been pushing himself to play with more aggressiveness in tight and tough moments. He wins a great deal of matches by using his destructive serve and then doing just enough on return, but also loses them by becoming a human backboard against opponents who are willing to try to take a risk on important points.<\/p>\n

Against de Jong, there were encouraging signs that Zverev won\u2019t retreat into his shell as the thing he wants more than anything else comes into sharper focus. He ripped groundstrokes, attacked the net with conviction, and played a few well-timed drop shots.<\/p>\n

Far bigger tests than the world No. 106 await, though, starting with a quarterfinal Tuesday against rising Spanish star Rafael J\u00f3dar.<\/p>\n

Zverev knows there will be constant questions about whether he is feeling the pressure, and in his news conference after beating de Jong, he tried to downplay the idea that his mind is wandering to what could await on Sunday.<\/p>\n

\u201cLook, I\u2019m here, I\u2019m feeling confident with my game. I feel like I\u2019m handling the situations quite well, and I will do everything possible to continue doing that,\u201d Zverev said in his postmatch news conference.<\/p>\n

Other notable results on Day 8:
\nRafael J\u00f3dar (27), the 19-year-old Spaniard, came back from two sets down for the first time to defeat Pablo Carre\u00f1o Busta 4-6, 4-6, 6-1, 6-2, 6-2.
\nSorana C\u00eerstea (18) advanced to the third Grand Slam quarterfinal of her career, 17 years after her first. The 36-year-old Romanian defeated Wang Xiyu (Q) of China 6-3, 7-6(4).
\nMirra Andreeva (8) of Russia eased past Switzerland\u2019s Jill Teichmann 6-3, 6-2 to reach her third French Open quarterfinal.
\nJakub Men\u0161\u00edk (26) of the Czech Republic survived a comeback from Russia\u2019s Andrey Rublev (11)\u00a0to win 6-3, 7-6(6), 4-6, 2-6, 6-3 and move into his first Grand Slam quarterfinal.

Up next: Fourth round continues<\/p>\n

\ud83c\udfbe Men\u2019s singles: Flavio Cobolli (10) vs. Zachary Svajda<\/p>\n

5 a.m. ET on Max<\/p>\n

The ruthlessness with which Cobolli dispatched Learner Tien, the American No. 18 seed, to reach the fourth round suggests that he is in the mood to take advantage of the opportunity in front of him. The 24-year-old Italian meets another American, 23-year-old Svajda, who beat clay-court expert Francisco Cer\u00fandolo in the previous round despite having played fewer than 10 tour matches on the surface.<\/p>\n

\ud83c\udfbe Women\u2019s singles: Maja Chwalinsk\u00e1 (Q) vs. Diane Parry<\/p>\n

8 a.m. ET on Max<\/p>\n

Two of the most unexpected names in the fourth round of this French Open collide. Chwalinsk\u00e1, the 24-year-old Pole, has been weaving opponents into webs with her heavy topspin forehands and sneak attacks on the net, while 23-year-old Frenchwoman Parry has used her skidding slice to drive her opponents to distraction. A fascinating clash of styles for two players who had nothing to lose and suddenly have everything to gain.<\/p>\n

\ud83c\udfbe Men\u2019s singles: Frances Tiafoe (19) vs. Matteo Arnaldi<\/p>\n

1 p.m. ET on TNT, HBO Max<\/p>\n

Tiafoe came from two sets down to beat Portuguese qualifier Jaime Faria in the previous round, helped by an exchange of views at the net in which he told Faria to \u201cstop acting like you\u2019re tough.\u201d This match against Italy\u2019s Arnaldi is likely to be very tough indeed, with both men coming off five-set matches and having to manage serious opportunity in their comparatively gentle half of the draw.<\/p>\n

\ud83c\udfbe Women\u2019s singles: Aryna Sabalenka (1) vs. Naomi Osaka (16)<\/p>\n

2:15 p.m. ET on TNT<\/p>\n

The first women\u2019s night session match since 2023<\/a> is all star power. Sabalenka and Osaka have eight Grand Slam titles between them, they have both been world No. 1, and they are two of the biggest stars in the sport. Osaka has served at an elite level all week, and she will need that again to really trouble Sabalenka.<\/p>\n
