Even in professional games with umpires and technology, the score can occasionally be off. Famously, no one noticed when the umpire awarded Karolina Sprem an extra point in a tiebreak during Venus Williams and Karolina Sprem’s match at Wimbledon in 2004. Williams ultimately lost the game. Even more difficult situations arise in unrefereed games, where it is up to the players to ensure accuracy and resolve any problems.
Calling out scores clearly before the start of each point as well as each game is the best approach to prevent scoring disagreements. If there is a disagreement over who won a point or game, the players must go back to that point or game and continue the game from there. However, when stakes are high, as they usually are in competitive games, things get ugly in case of tennis score-keeping where riffs can range from verbal to even physical fights. Here are some of the examples which show the extent of such altercations:
Rafael Nadal:
The fact that Thomas Berdych and Rafael Nadal have some tennis court history added intrigue to this match even before it began. But when the umpire rendered contentious decisions, the situation erupted. It appeared as though Berdych was about to lose his cool and spit the dummy out after a very late overrule from the chair, but he instead chose to contest the call. The umpire decided to award Berdych the point rather than ordering a replay as Hawk-Eye revealed that the ball was in (by a few millimeters). Not only had he stopped playing, but he had also put the ball back on the court. Nadal did not appreciate this at all. Only if Berdych’s shot was determined to be non-returnable should he have been given the point. It is challenging to assert that a ball is non-returnable when it has already been returned!

Serena Williams:
Serena Williams has a strong personality and will not tolerate ridicule, despite the fact that she enjoys doing so. Serena was feeling emotional during the 2011 U.S. Open final. She made a stunning comeback to the game in time for the Flushing Meadows event after missing a year due to an injury and health issues. After winning the match and facing Sam Stosur in the final, Serena swiftly lost the match. Serena quickly celebrated a strong forehand winner when she faced yet another breakpoint. She was hasty in her celebrations, which was a concern.
Things rapidly went south when she learned that Stosur had won the point as a result of the early celebration.
John McEnroe:
This eruption at Wimbledon in 1981 will go down in history as one of the greatest on-court fights ever, immortalized by Hugh Laurie in British comedy skits. Even for McEnroe, the altercation wasn’t particularly rough or harsh; rather, it was his open disrespect for the umpire that startled the Wimbledon crowd.
Jimmy Conors:
Throughout his playing career, Jimmy Connors was always a colourful character, but on the day of his 39th birthday at Flushing Meadows, tensions were particularly high. The elderly Connors knew he needed things to go his way if he was to win against the young Aaron Krickstein, who was only 24 years old. The issue is that not everything went his way; in a first-set tiebreaker, the chair umpire overturned a call that arguably shouldn’t have been overturned. Then it began. The five-time U.S. Open winner Connors unleashed a barrage of vulgar insults at the umpire to express his frustration.

Jeff Tarango:
The American abruptly terminated his tournament in 1995 at the All-England Club by storming off the court mid-match. Things got out of hand after a disputed call and Tarango insisted on speaking to the umpire supervisor, who was unable to defuse the situation. Tarango had had enough and exited the court after being given a code violation for alleging that umpire Bruno Rebeuh was corrupt. Mr. Tarango never spoke to Mr. Rebeuh again, but his wife waited outside the restroom and slapped him when he came out.
