Australian Open: Did the Happy Slam become the Angry Slam? Or is tennis just changing?

MELBOURNE, Australia — Things are somewhat out of control at the Australian Open this year, and that's got only a little to do with the results on the courts.

Yes, there were some upsets, including Madison Keys eliminating No. 2 Iga Swiatek in the women's semifinals Thursday night. It also was the first time since 1990 that three teenagers beat top-10 men's seeds at a Grand Slam tennis tournament. The loser of one of those matches, Daniil Medvedev, got fined $76,000 for behaving badly. Last year's women's runner-up exited in the first round.

Ho, hum. The real fuss is happening elsewhere. The rowdy fans, for one thing, continuing a recent increase in loud and unruly folks in the stands at Grand Slam tennis tournaments, whether calling out during points or between points, or booing lustily — even when Novak Djokovic stopped playing in the men's semifinals Friday because of a leg injury — or causing such a ruckus at a court equipped with a bar that an adjacent match was moved to a different venue.

''It's been like that for a couple of years. ... Sometimes I think it's disrespectful,'' said Pat Rafter, a retired Australian player who won two U.S. Open titles and reached the No. 1 ranking in the late 1990s. ''Sometimes, I think it's just part of the game, the transition of this generation, and that's what they want. This is the Australian Open.''

Also drawing attention: Some folks involved in television coverage at Melbourne Park, whether those whose interviewing skills were lampooned on social media — and described as " embarrassing '' by Ben Shelton, the American who reached the men's semifinals — or the commentator who insulted Djokovic during an on-air appearance before eventually apologizing days later after the 24-time Grand Slam champion demanded it.

So what is going on, exactly? Why is everyone so angry at what long has been known as the Happy Slam?

It's hard to pinpoint one reason. And, in truth, it could just be coincidental, rather than a reflection of Australian society or any sort of trend in modern-day tennis.

Or perhaps it's an increasing willingness on the part of the athletes to call out what they consider bad behavior and give as good as they get, something American Danielle Collins did after hearing boos when she defeated an Australian player and Djokovic has done more than once.

It also might stem from attempts by tennis leaders to, as Rafter noted, attract new fans and, especially, younger fans.

That's seen in various ways, from allowing movement in the stands while play is in progress — something unheard of for decade upon decade — to permitting coaching during contests and making it part of the spectacle with courtside boxes or trying to meet kids where they are by posting feeds on YouTube of real-time animated streams of matches made to look like a video game.

Could be working: As the event heads to Sunday's conclusion, 10 of the first 12 days had record attendance, including more than 97,000 on site on Jan. 17, the highest one-day number in tournament history.

''It's fun in Australia. It's a place where you see people coming from all over the world, which creates a great atmosphere. Sometimes, I think ... it can go a little bit over the line. There are traditions in tennis that are important that make tennis unique,'' said Patrick McEnroe, an ex-player and former captain of the U.S. Davis Cup team.

This whole phenomenon is not unique to Melbourne Park, though.

Unusual scenes have been playing out in the stands at Roland Garros, Flushing Meadows and — gasp! — even the All England Club.

During the 2022 Wimbledon final, Nick Kyrgios got into a back-and-forth with one particularly bothersome spectator, who later sued him. Crowds at the U.S. Open have been notoriously rambunctious for a while, especially when the drinks flow at night, including the jeering that drowned out the trophy ceremony when Naomi Osaka defeated Serena Williams in the 2018 women's final.

Last year, French Open organizers stopped letting ticket-holders bring alcohol to their seats after one player, Belgian David Goffin, complained about having gum spat at him.

''It's becoming soccer,'' Goffin said. "Soon there'll be smoke bombs, hooligans and fights in the stands. I think it's getting ridiculous.''
