Late on a Sunday night at Roland Garros, on Court Philippe-Chatrier, João Fonseca closed out a fourth-round match with a forehand and became the first Brazilian man to reach the Paris quarter-finals since Gustavo Kuerten in 2004. He was nineteen. Kuerten watched from the stands.
The result read 7-5, 7-6(8), 5-7, 6-2.
The contest ran to nearly four hours of high-quality tennis, three sets decided 7-5 or 7-6, with almost no breaks of serve until the final exchanges.
Fonseca took the opening set 7-5 with a single break in the twelfth game, after eleven straight games of holds.
Where it was decided
The second set held the match.
Ruud led 5-2 in the tie-break before Fonseca clawed back to 5-5, surged ahead, was levelled at 7-7, and finally took it 10-8.
One moment inside it drew the eye.
At 8-7 to Ruud, a Fonseca forehand landed near the baseline; Ruud stopped play and asked the chair umpire to check the mark, arguing the ball was long.
The umpire came down, examined the mark, ruled that it touched the line, and awarded the point to Fonseca, though television replays later placed the ball out.
Instead of losing the set, the Brazilian was level, and he closed it.
Casper Ruud, the fifteenth seed and a two-time finalist here, answered.
He held until the twelfth game of the third, then found the break to take the set 7-5, the mirror image of Fonseca's opener.
The fourth set turned quickly.
Fonseca broke Ruud on his first service game and again at 1-3 to lead 4-1, then ran the set out 6-2, playing the most aggressive tennis of the night.
Both men hit 51 winners and landed more than 70 percent of their first serves; Fonseca saved seven of the nine break points he faced.
The road there
This was no isolated week.
Fonseca came from two sets down to beat Dino Prizmic in the second round, and from two sets down again to beat Novak Djokovic in the third, becoming the first teenager to beat Djokovic at a Grand Slam.
Against Ruud he did the harder thing, which is to follow one landmark with another.
He is the youngest of the five Brazilian men to reach the Roland Garros quarter-finals in the Open era.
The witness gave the night its weight.
Kuerten, the last Brazilian man to win a Grand Slam, had watched Fonseca's first Roland Garros match, in the boys' singles, four years earlier.
Fonseca spoke of him afterwards.
"He's an idol for our sport, for our country. For his charisma, for the way that he is, for how humble he is. It's a pleasure to win against a very tough opponent in front of him."
A boy who once played on the outer courts, now the last eight, watched by the man he came to follow.
