Outfit of the Day: Jannik Sinner’s saucy Australian Open kit divides the Internet

Two-time defending champion Jannik Sinner knows his way around Rod Laver Arena—but after two wins in Melbourne, his latest Australian Open look is proving far more divisive than his tennis.

The world No. 2 first returned to Rod Laver Arena on Tuesday to face Hugo Gaston, giving fans their first look at his Melbourne wardrobe. For night matches, Sinner is wearing NikeCourt’s Men’s Slam Dri-FIT polo and matching shorts in a muddy olive green, while daytime sessions feature a bright lemon yellow set.

The colorways have sparked plenty of debate. Some fans on social media enjoy the bold choices, while others have called it one of the worst combinations they’ve seen. The Daily Mail even posed the question in a headline: “Is Jannik Sinner’s Australian Open outfit the worst in the history of tennis?” Its verdict was a resounding “YES”.

Sinner, for his part, seems to be taking it all in stride. After sporting a head-to-toe neon yellow kit during a pre-tournament charity match, he joked that he’d like a bit more creative control in the future.

“Next year I have a little bit more of a say in the colors!” Sinner told reporters in Melbourne with a laugh. “But I’m very, very happy to wear this outfit.”

Adding to the online chatter is a viral graphic comparing Sinner’s recent kits to a lineup of colorful condiments. Alongside “Yellow Mustard,” there's an off-white look that's been dubbed “Mayo,” last year’s red Roland Garros ensemble “Tomato Ketchup,” and this week’s olive number “Dill Relish” to complete the 'Sauce Slam'.

The debate even reached Tennis Channel’s studio. When host Steve Weissman asked Prakash Amritraj, Lindsey Davenport and Martina Navratilova on TC Live to pick a favorite, the panel was split.

“Oh man… Favorite? Well, maybe the favorite hasn’t shown up yet!” Navratilova offered diplomatically, before predicting his next shade: “It’s going to be Vegemite next year, Vegemite brown.”

Off the court, Sinner’s style tends to be more understated. The Italian, a global ambassador for Gucci, recently spoke about his preference for relaxed, functional pieces in pure neutral tones.

“In my wardrobe, there are a lot of very simple t-shirts. White or black, usually, because I travel around a lot,” he told Street Style Australia  (@whatpeoplewear.au). “For sure a nice jacket has to be there.”

For now, though, the focus remains on his tennis. Ranked No. 2 in the world, Sinner is chasing his fifth Grand Slam title in Melbourne—and a third consecutive Australian Open crown—while extending his 16-match win streak at the tournament.

So far, so good. Sinner has yet to drop a set through his opening matches. Gaston was forced to retire from their first-round clash while trailing 6-2, 6-1, and on Thursday night—again in “Relish” green—Sinner dispatched Australian wild card James Duckworth in straight sets, 6-1, 6-4, 6-2.

The No. 2 seed will next face American Eliot Spizzirri in the third round.
