In tennis, the line judge is supposed to be an impartial observer, just there to call the lines and keep things fair. However, for some players, that person standing at the baseline becomes Public Enemy No. 1 when a call doesn’t go their way.
These tennis stars didn’t just question the calls—they asked about the very existence of line judges. From icy stares to full-blown meltdowns, these players made it clear: Disagree with them at your own risk.
15. Daniil Medvedev

Medvedev doesn’t just argue—he rants. A missed call can quickly spiral into a dramatic monologue with plenty of sass and finger-pointing.
14. Jelena Ostapenko

Subtlety is not Ostapenko’s thing, especially when she thinks the line judge is blind. She’s been known to shout, scoff, and roll her eyes like it’s a Broadway performance.
13. Fabio Fognini

Fognini treats line judges like they insulted his entire family. The man brings an opera-level intensity to every single disagreement.
12. Andy Roddick

Roddick’s sarcasm was his signature weapon, and line judges often bore the brunt of it. He’d raise an eyebrow, drop a one-liner, and completely unravel over one close call.
11. Martina Hingis

Hingis could be icy and cutting when she didn’t like a call. Her glares alone could cause a line judge to reconsider their career choice.
10. Nick Kyrgios

Kyrgios has turned fighting with line judges into a full-blown subplot of his matches. He doesn’t hold back, and the drama almost always follows.
9. Marat Safin

Safin didn’t just yell—he destroyed rackets, stared down officials, and questioned reality. The line judge was often just collateral damage in the chaos.
8. Aryna Sabalenka

Sabalenka wears her emotions on her sleeve, including some less-than-friendly reactions to line calls. The death stares are immediate and unrelenting.
7. Ernests Gulbis

Gulbis had a short fuse and a long list of complaints, many of which were directed at line judges. He brought a chaotic energy that always kept the umpires on edge.
6. Serena Williams

Serena is a legend, but she’s had some unforgettable blowups involving line judges. When she feels disrespected or wronged, the intensity goes through the roof.
5. Bernard Tomic

Tomic often seemed more interested in arguing than competing, and line judges were easy targets. His energy was less “passionate disagreement” and more “full-on sulk.”
4. Andre Agassi

In his early years, Agassi’s rebellious streak included many confrontations with officials. His glare was lethal, and his protests were frequent.
3. Victoria Azarenka

Azarenka doesn’t hold back when she thinks she’s right, including sharp words for line judges. Her voice goes up, her hands go out, and the fireworks start fast.
2. John McEnroe

The gold standard of losing it on a line judge. No one—and I mean no one—did full-volume outrage better than Johnny Mac.

1. Novak Djokovic

Djokovic has had enough line judge drama to fill a documentary, including the time he accidentally hit one with a ball and got defaulted from a Grand Slam. At this point, it feels like he’s cursed regarding line officials.
