ROME — We will soon find out how much of what happened Sunday at the Italian Open was foreshadowing.

The main draw for the French Open, the only Grand Slam tournament played on clay courts, begins in a week. But Iga Swiatek’s and Novak Djokovic’s decisive victories in Rome certainly solidified two key themes heading into Paris.

Swiatek continues to look irresistible, and Djokovic now looks fully revitalized.

Both are ranked No. 1 in singles and playing like it. Neither dropped a set on the way to their Italian Open titles, and both polished off their runs convincingly against top-10 players in Sunday’s finals. Swiatek defeated Ons Jabeur, 6-2, 6-2, to stop Jabeur’s 11-match winning streak and extend her own to 28. Djokovic followed her lead, defeating Stefanos Tsitsipas, 6-0, 7-6 (5).

Swiatek and Djokovic are at opposite poles of their careers.

Swiatek, 20, is just now harnessing the full force of her hard-charging power game, grasping that she can be not only a serial champion but also an intimidator as she crowds the opposition with her heavy-topspin forehand and acrobatic, tight-to-the-baseline defense.

Djokovic, who will turn 35 on the opening day of Roland Garros, established himself years ago as one of the game’s greatest players. He is the oldest man to win the Italian Open in singles in the Open era: slightly older than his longtime rival Rafael Nadal was when he beat Djokovic to win the title at 34 last year.

Djokovic has endured long enough that he was not the only Djokovic playing for a title on Sunday. While he was prevailing in Rome, his 7-year-old son, Stefan, was winning the title at his debut tournament at a club in the Serbian capital of Belgrade.

“I just received that news: a sunshine double today,” Djokovic said with one of his biggest smiles of the week.

I mentioned to Djokovic that it has been said that the only thing more mentally challenging than being a tennis player is being a tennis parent.

“Not a single day have I told him you have to do this; it’s really purely his own desire to step on the court,” Djokovic said. “He’s really in love with the sport. Last night, when I spoke to him, he was up till late. He was showing me forehand and backhands, how he’s going to move tomorrow, kind of shadowing, playing shadow tennis without a racket. It was so funny to see that. I used to do that when I was a kid. I could see the joy in him, the pure emotion and love for the game.”

Djokovic, like his career-long reference points Nadal and Roger Federer, has underscored his passion with long-running excellence and by persistently ignoring the hints that his peak years might be behind him.

For Djokovic, this has been a season and a challenge like no other: His decision to remain unvaccinated against the coronavirus led to a standoff with Australian authorities that ended with his deportation on the eve of this year’s Australian Open, and it kept him out of the Masters 1000 events in Indian Wells, Calif., and Miami Gardens, Fla., in March.

But with the health protocols now relaxed in Europe, Djokovic returned to regular action on clay last month. Though he struggled in his initial matches with his timing and his endurance, he has slowly but convincingly resumed hitting his targets, and he has gathered momentum just in time for Roland Garros.

“I always try to use these kinds of situations and adversity in my favor to fuel me for the next challenge,” he said of Australia. “As much as I’ve felt pressure in my life and my career, that was something really on a whole different level. But I feel it’s already behind me. I feel great on the court. Mentally as well, I’m fresh. I’m sharp.”

Against Tsitsipas, the hirsute Greek star who pushed Djokovic to five sets before losing last year’s French Open final, Djokovic controlled most of the baseline rallies with as much patience as panache. When Tsitsipas failed to serve out the second set, Djokovic proved the more reliable force in the tiebreaker, perfectly content, it seemed, to wait for Tsitsipas to crack.

“To some extent, it’s a relief because after everything that happened at the beginning of the year, it was important for me to win a big title,” Djokovic said.

It might have been even more reassuring if his title had come against a full-strength field. But Carlos Alcaraz, the 19-year-old from Spain who has been the revelation of the season, chose to rest and skip the Italian Open after beating Nadal and Djokovic to win the title in Madrid. Nadal, the greatest clay-court player in history, lost in the quarterfinals, limping and wincing in the final set of his defeat against Denis Shapovalov of Canada as he struggled anew with the chronic pain in his left foot that threatened his career in his teens and imperils it again now at age 35.

Nadal has won the French Open a mind-boggling 13 times; Djokovic a more terrestrial two. But as counterintuitive as it is to count Nadal out in Paris, it seems right to bump him down the list of favorites this year, all the more because he might not even compete.

“Right now, Carlos Alcaraz or Novak Djokovic,” said Tsitsipas, who lost to both men this month. “They both play great, great tennis. I would put them as favorites.”

It is tempting to lean toward Djokovic considering that Alcaraz has so little experience in the best-of-five-set format and no experience in managing the stress that can come with being placed on a Grand Slam shortlist. But he held up astoundingly well in Madrid despite all the pressure from Djokovic’s groundstrokes and timely first serves down the stretch.

Alcaraz is undoubtedly special. The question is just how special, which seems a fine line of inquiry for Swiatek, as well. She was on a roll even before Ashleigh Barty retired suddenly in March while holding the No. 1 ranking. But Swiatek has filled the role with true swagger, solving all manner of riddles by lopsided margins.

Since her winning streak began in February, she has lost just five sets and came genuinely close to losing a set only once in Rome, prevailing over the 2019 U.S. Open champion Bianca Andreescu in a first-set tiebreaker in the quarterfinals before closing her out, 6-0.

Jabeur, a tactic-shuffling Tunisian, won the title in Madrid on clay this month in Swiatek’s absence. But Sunday represented a big step up as Swiatek not only hunted down most of Jabeur’s trademark drop shots but also dealt firmly with most of Jabeur’s full-force bolts into the corners.

There was not much genuine danger, but when it surfaced Swiatek was prepared. Up, 4-2, in the second set but down, 0-40, on her serve, Swiatek saved three break points with winners, and then saved a fourth with a backhand drop volley to cap a full-court exchange.

She was soon sobbing on the clay behind the baseline after securing her fifth straight title. Clearly, winning is more taxing than Swiatek is making it look, but after wiping away the tears, she was back to grinning in the Roman sunshine and holding up yet another trophy to go with those won in Doha, Qatar; Indian Wells; Miami Gardens, and Stuttgart, Germany.

“Today, I’m going to celebrate with a lot of tiramisù, no regrets,” she said, suddenly much more relatable than when she was pounding the opposition into clay dust.

It would come as no surprise if more desserts awaited in Paris.
