The most controversial moments in tennis
Serena William’s altercation with Chair Umpire Carlos Ramos (2018 US Open)
Tennis legend Serena’s outburst with Ramos will go down as one of the most controversial moments in tennis, involving a sensitive accusation and overshadowing what was meant to be a historic win for a young Osaka.
The 2018 US Open Women’s Singles final between Serena Williams and Naomi Osaka was a highly controversial match.
The controversy began when Ramos issued Williams a code violation for receiving coaching from her box, a practice that is against the rules.
Williams vehemently denied receiving coaching and argued with Ramos. The argument escalated when Ramos issued a second code violation for racket abuse. Williams then accused Ramos of sexism and demanded an apology.
“You owe me an apology,” Williams said to Ramos, a seen in a video shared by sportscenter on X.
“You’re a thief, too,” she added.
Ramos then issued a third code violation for verbal abuse, resulting in a game penalty. This penalty put Osaka within one game of victory, and the match was ultimately won by Osaka in straight sets.
¡Escándalo americano! Serena insultó al umpire, lloró y perdió. Williams se puso furiosa por una advertencia, le descontaron un punto por romper su raqueta y un game por abuso verbal. Le dijo "ladrón" al juez y estalló en lágrimas. Un final que nadie imaginó. pic.twitter.com/fmd8qRZK6J

The incident sparked a heated debate about sexism in sports and the treatment of female athletes. Many argued that Williams was unfairly penalized and that Ramos’s decisions were influenced by gender bias. Others defended Ramos’s decision, arguing that he was simply enforcing the rules.
This raised questions about the role of technology in officiating and the need for greater consistency in enforcing the rules.

A racially motivated dispute tainted the 2001 US Open match between Lleyton Hewitt and James Blake, which had started as an exciting battle in the second round. An African-American linesman called several foot faults against Hewitt in the third set, which led to the confrontation.
Hewitt became frustrated with the calls and used racially offensive comments to vent his frustration at the umpire, Andreas Egli.
Hewitt complained,
“Change him, change him. I have only been foot-faulted at one end. OK. Look at him. Look at him, and you tell me what the similarity is. Just get him off the court. Look at what he’s done.”
The crowd, sensing the racial undertones, reacted with jeers and boos, further escalating the tension. Hewitt’s comments sparked widespread debate and accusations of racism, with many critics condemning his behavior.
However, Hewitt strongly denied any racial purpose in spite of the criticism, saying that his remarks were misunderstood. He insisted that the line judge’s erratic calls, not his race, were the source of his annoyance.
