The takeaways from Carlos Alcaraz’s fifth-set tiebreaker victory over Jannik Sinner in the riveting and record-breaking French Open men’s final were multiple and significant. Let’s start with this: Anyone worried about how men’s tennis would survive in the post-Big Three era can rest easy. Alcaraz and Sinner produced 5 1/2 hours of evidence Sunday that the game is in good hands, and that their rivalry will be, and perhaps already is, a transcendent one.

Take it from no less an authority than Roger Federer. The retired owner of 20 Grand Slam titles, and rival of Rafael Nadal (22 majors) and Novak Djokovic (24), began a post on social media by declaring, “3 winners in Paris today”, then listed Alcaraz, Sinner and “the beautiful game of tennis. What a match!” No. 1 Sinner and No. 2 Alcaraz could renew their rivalry at Wimbledon. This was the 12th Alcaraz-Sinner meeting, the first in a major final.

“Hopefully not the last time,” Alcaraz said. “Every time that we face each other, we raise our level to the top.” It would be shocking if there weren’t many more of these to come, perhaps as soon as Wimbledon, where play begins on June 30 and No. 2-ranked Alcaraz is the two-time defending champion.

His comeback against No. 1 Sinner from two sets down, then three championship points down, to win 4-6, 6-7 (4), 6-4, 7-6 (3), 7-6 (10-2) was unprecedented at Roland-Garros. It was unforgettable. Alcaraz’s coach Juan Carlos Ferrero described his guy’s best trait this way: “His strength is (to) keep believing all the time, until the last ball is gone.” Carlos Alcaraz has five Grand Slam titles at age 22— that’s the age at which Nadal, Bjorn Borg and Pete Sampras also got to five; no one’s done it younger — show how special he is. So does the Spaniard’s 5-0 record in major finals, a career start surpassed among men only by Federer’s 7-0.

Sinner is pretty good, too. Tuesday marks a full year that he has been ranked No. 1. He has reached the finals of his last eight tournaments, a run last accomplished by Djokovic a decade ago. He has won three majors. He has won 47 of his last 50 matches. Notably, all three of those losses came against — yes, you guessed it — Alcaraz. That hearkens back to the days when Federer would beat everyone other than Nadal.

Sinner had claimed 31 Slam sets in a row right up until the moment he was up 2-0 against Alcaraz. What was unmistakable was that Alcaraz vs. Sinner was a must-see.

“The level,” Alcaraz said, “was insane.” Alcaraz and Sinner have won the last 6 Grand Slam titles. Sinner’s take? “I’m happy to be part of this,” the 23-year-old Italian said. “Would be even more happy if I would have … the big trophy.” As with any great rivalry — think Evert vs. Navratilova or Borg vs. McEnroe or Federer vs. Nadal, no first names needed — Alcaraz vs Sinner provides a clash of excellence and a study in contrasts.
