Tennis might be a gentleman’s (and gentlewoman’s) sport, but not every player keeps their cool when things don’t go their way. From wild rants to icy stares, some of the biggest names in tennis have a long history of making the chair umpire feel like the villain in a one-person drama.
Whether it was a bad call, a missed let, or just a general vibe that didn’t sit right, these players weren’t afraid to unleash their fury. Some treated the umpire like a punching bag, others like a petty rival, but all of them made their feelings very clear. Let’s count down the 20 tennis stars who acted like the umpire was their sworn enemy.
20. Jelena Janković

She had talent, flair, and a short fuse when it came to authority figures in the chair. Her sarcasm toward umpires was almost an art form.
19. Ernests Gulbis

Gulbis never really met a rule he didn’t want to debate. Umpires often found themselves stuck in philosophical arguments mid-match.
18. Bernard Tomic

Tomic’s effort was questionable, but his snark toward umpires was fully committed. When he wasn’t tanking, he was usually arguing.
17. Fabio Fognini

A walking firecracker, Fognini had a habit of exploding at umpires over anything and everything. His rants were often louder than the actual crowd.
16. Benoît Paire

Paire’s tennis could be mesmerizing, when he wasn’t too busy going toe-to-toe with the umpire. From smashed rackets to theatrical monologues, he treated the chair like a rival co-star in a never-ending drama.
15. Lleyton Hewitt

Hewitt had a chip on his shoulder and didn’t hesitate to direct it upward toward the chair. He questioned calls with the intensity of a lawyer on closing arguments.
14. Svetlana Kuznetsova

She brought a quiet intensity that turned fiery when calls didn’t go her way. One line call, and she was ready to launch into a full protest.
13. Nick Kyrgios

It’s not a list without him. He’s gone full Shakespeare with his umpire theatrics: yelling, sulking, and occasionally just ignoring them entirely.
12. Jelena Ostapenko

Ostapenko doesn’t do subtle. She’s known to make umpires feel like they personally ruined her day.
11. Daniil Medvedev

Medvedev’s “Are you stupid?” moment was just the tip of the iceberg. His relationship with umpires is best described as… complicated.
10. Marcos Baghdatis

Baghdatis could go from charming to chaotic in a matter of seconds. His epic racket-smashing tantrum also included a few choice words for the umpire.
9. Victoria Azarenka

Azarenka was not one to bite her tongue. If she didn’t agree with a call, the umpire would absolutely hear about it, sometimes for several games.
8. Marat Safin

Safin brought drama to the court like few others. When he disagreed with a call, his theatrical reactions practically demanded a standing ovation.
7. Aryna Sabalenka

Her power game carries over to her arguments. When she’s frustrated, umpires are often the first to feel the full weight of it.
6. Andy Roddick

Roddick’s sarcasm could cut glass, and umpires were frequent recipients. He once mimicked an umpire’s voice mid-match to prove a point, iconic chaos.
5. Serena Williams

Serena is one of the greatest ever, but she’s had some unforgettable clashes with umpires. When she feels disrespected, she doesn’t hold back.
4. Ilie Năstase

Năstase basically invented tennis misbehavior. His antics were so relentless that umpires had to brace themselves before every match.
3. Martina Hingis

Don’t let the smile fool you, Hingis had a fiery side. When she didn’t agree with a call, she’d let the umpire know with biting wit.
2. Jimmy Connors

Connors played every match like it was war, and the umpire was just another opponent to defeat. His legendary rants are still being talked about decades later.
