One Swing and Out: How a Tennis Player Gets Defaulted

The man in the front row did not see it coming, and that is the whole problem.

It was Monday night in Beijing, the second semi-final of the China Open, and Daniil Medvedev was losing. Novak Djokovic had taken the first set 7-5 and led 5-3 in the second, serving at 15-15. Djokovic put away a forehand volley. The ball ricocheted off the advertising boards and came trundling back towards Medvedev, the way loose balls do a hundred times a match. Medvedev flicked a backhand at it without really looking.

The ball went into the first row of the crowd and hit a spectator in the face, around the eye.

What happened next took about three minutes and ended Medvedev's tournament. The chair umpire, Mohamed Lahyani, came down from his chair. The ATP supervisor walked onto the court. The spectator was helped up out of his seat, one hand pressed over his left eye, and led out of the arena. Medvedev stood there and listened, and when he was told he was defaulted he barely argued. He packed his bag. Djokovic was through to a final he had not finished playing for.

If you watch tennis without playing it, that sequence probably looked arbitrary. It was not. It was one of the oldest and least forgiving rules in the sport doing exactly what it was written to do, and this is a good week to understand it, because the tour has moved straight on to Shanghai and Medvedev is in that draw as the fifth seed, carrying all of it with him.

The ladder that most defaults never use

Ask a tennis fan how a player gets thrown out and they will usually describe a staircase. They are half right.

The code of conduct runs on a graduated scale. The first offence is a warning: the umpire says the words, writes it down, and the score does not change. The second offence costs you a point, handed to your opponent. The third costs you a game. After that, the tournament supervisor decides whether the next one ends your afternoon.

Crucially, the steps are cumulative across the whole match and across different kinds of offence. A warning for taking too long between serves and a smashed racket two sets later are rungs on the same ladder. Players who think they are starting fresh because they have switched from one sin to another find out, usually loudly, that they are not.

That ladder is how John McEnroe went out of the 1990 Australian Open, in the fourth round, leading Mikael Pernfors 6-1, 4-6, 7-5, 2-4 and comfortably the better player on the day. He got a warning for staring down a lineswoman. He cracked a racket and swore, which cost him a point. Then he demanded the supervisor, Ken Farrar, come down and reverse it, and when Farrar would not, McEnroe swore at him as he walked away. Farrar told the umpire, Gerry Armstrong, to default the match.

The part that still makes people wince is why McEnroe did it. The code had just been tightened from four strikes to three. He did not know. He told reporters afterwards that he had no one to blame but himself, that he thought he still had one left. He was the first player disqualified under the new code, and depending on which record book you prefer, the first man removed from a Grand Slam event since 1963 or the first in the Open era.

That is the famous version of a default: a slow-motion collapse, three or four visible steps, a crowd that can see it coming. It is also the rare version.

The clause that caught Medvedev

Most modern defaults skip the staircase entirely.

Buried in the code is a clause for ball abuse, and it is written much more broadly than players seem to remember. It does not say you must not hit a ball at someone. It says you must not hit a ball violently, dangerously or in anger anywhere on the tournament grounds, and it extends to hitting a ball out of the court enclosure or striking one with no regard for where it ends up. The only exception is reasonable pursuit of a point. Everything else, in the language of the rulebook, is on you.

Sitting alongside it is the provision for serious misconduct, which allows officials to default a player immediately, with no warning and no point penalty first. When a struck ball hits a spectator, an official or a member of the tournament staff, that is the clause officials reach for. Intent is not part of the test. Nobody has to prove you meant it. The question is whether you hit the ball carelessly and whether it hit a person, and in Beijing both answers were yes.

Medvedev understood this better than his critics did. "It was 100 per cent an accident," he said afterwards. "You can see that I didn't hit the ball in anger." Both of those statements are almost certainly true, and neither of them is a defence under the rule as written. He said he hoped to meet the fan and make it up to him somehow. There is nothing performative about that; he looked genuinely shaken.

Djokovic, who stood a few metres away and won a semi-final without hitting another ball, said he had not even seen what happened. "I feel sorry for the person," he said. "I hope he is not injured." Then he added that he felt sorry for Daniil as well, which from a man who has lived through exactly this is not a throwaway line.

The club nobody wants to be in

Djokovic's own default is the one everyone reached for on Monday night, and the parallels are uncomfortable.

New York, September 2020, the fourth round of a US Open played in an empty stadium. Djokovic was broken to trail Pablo Carreno Busta 5-6 in the first set, turned away from the baseline and knocked a spare ball behind him without looking. It struck a line judge in the throat. She went down. After a long conversation involving the referee, Soeren Friemel, Djokovic was defaulted out of a tournament he was favourite to win, having not lost a match all year. Friemel accepted entirely that there was no intent, and defaulted him anyway, because the ball had been hit angrily and recklessly and that is all the rule requires.

Djokovic lost every ranking point and every dollar of prize money from that fortnight, and wrote on social media that he felt sad and empty. Carreno Busta, who had just been handed a quarter-final place he did not want in that fashion, said later that he was certain Djokovic had not meant to hit anyone, and made the observation that has haunted the rule ever since: if the ball had struck the official on the leg or the arm, it probably would have been a warning. The punishment depends not on what the player did but on where the ball landed on a stranger's body. Medvedev himself has been the subject of plenty of close reading over the years, and he will have known the precedent perfectly well as he stood there in Beijing.

The list goes back further and stranger than most fans realise.

David Nalbandian, Queen's Club, June 2012, in the final. He had just dropped serve to Marin Cilic and he kicked out at the low advertising board that boxes in the line judge's seat. The panel caught the official on the shin and opened a cut. The umpire, Fergus Murphy, defaulted him. Cilic was handed the title at 7-6, 4-3, which is a thoroughly miserable way to win a trophy, and Nalbandian lost a reported 51,000 dollars in prize money along with the chance to lift one.

Tim Henman, Wimbledon 1995, first-round doubles with Jeremy Bates. He missed a shot, batted the ball away in irritation and hit a 16-year-old ball girl on the head from almost point-blank range. The pair were defaulted. The crowd booed the officials, which tells you something about how British sympathy works, and Henman has spent thirty years explaining that he was, as he puts it, the first player disqualified at Wimbledon in 125 years.

Miyu Kato, Roland Garros 2023, third round of the women's doubles. Her ball hit a ball girl, who was left in tears. The chair umpire initially gave only a warning. Then the tournament referee and the Grand Slam supervisor reviewed it and defaulted Kato and her partner Aldila Sutjiadi anyway. Kato forfeited her prize money and her points, appealed, lost the appeal and was fined on top. Four days later she won the mixed doubles title with Tim Puetz, beating Bianca Andreescu and Michael Venus, which is the kind of plot the sport writes when nobody is asking it to.

And this July, on Court 11 at Wimbledon, a 15-year-old German called Ida Wobker lost the first set of a junior match 6-0 to Maria Valentina Pop and, at 5-5 in the second, threw her racket down hard enough that it bounced up into the few rows of seats beside the court. Nobody was hit. Nobody was hurt. She was defaulted for unsportsmanlike conduct all the same, apologised to the spectators nearest where it landed, and because junior events pay no prize money there was nothing to fine her. She is fifteen and will carry that around for a while.

Not every default involves a ball, either. Alexander Zverev was removed from the Mexican Open in Acapulco in 2022 after a doubles defeat, when he walked to the umpire's chair and hit it repeatedly with his racket, with the official, Alessandro Germani, still sitting in it. Nobody was injured. He was thrown out of the tournament all the same, and his singles opponent was handed a walkover he had done nothing to earn.

Which raises the question fans ask every time: who actually decides?

Almost never the chair umpire alone. The umpire calls the violation and stops the match, but the decision to end someone's tournament belongs to the tournament supervisor on the ATP and WTA tours, or to the referee at a Grand Slam. That is why these moments always look the same on television: a long, awkward conference at the net or beside the chair, a radio call, a middle-aged official in a polo shirt walking out of a side door and across the court while twelve thousand people watch and nobody knows what is being said. The player is usually allowed to make their case. Djokovic argued at length in New York, pleading for a game penalty or a set penalty instead. Medvedev barely argued at all in Beijing, which may tell you he already knew how it was going to go.

The supervisor also has a power most fans never see used: after a default for misconduct, a player can be pulled out of every other event they are entered in at that tournament, doubles included.

What links all of them is not temper. Two of the six were not angry at all. What links them is a loose object leaving a player's control in a building where the nearest human being is sitting a few steps away with nothing in front of them.

The bill

Defaults do not just end a match. They reverse it.

Medvedev had already banked a semi-final in Beijing: 200 ranking points and prize money reported at around 219,000 dollars. He lost all of it. Not the difference between a semi-final and a final, all of it, as though the week had not happened. He also lost the chance to close ground in a race for the eight places at the season-ending finals in Turin that is going to come down to margins this thin. Three points from the end of a set he was probably losing anyway, and an entire week of work went into the bin.

That forfeiture is the part fans find hardest to accept, and it is the part that makes the rule work. A player who kept the points would be gambling with house money. A player who loses everything thinks twice before swatting a loose ball, which is precisely the reflex the sport is trying to break.

Tennis is unusually exposed here. Think about where the spectators actually sit. In an arena like the one in Beijing, the front row is a few metres from the baseline, below the level of the court lighting, with no glass, no netting and nothing between a person's face and a ball that leaves a racket at speeds a car would get a ticket for. Baseball puts up screens. Ice hockey puts up glass and still hands out helmets to officials. Tennis puts out a row of chairs and trusts twenty-two-year-olds with adrenaline in their bloodstream to keep their hands still at the worst moment of their afternoon. The unwritten rules of the sport cover a great deal, but they cannot cover this one, so the written ones have to.

That trust extends to the people working the court. The ball crews at a big tournament are enormous operations staffed largely by teenagers who have trained for months for the privilege of standing very still while professionals hit at each other. They are the ones most often in the firing line, and two of the defaults above involved exactly that. Meanwhile the number of adults on court has been falling: the line judges have been replaced by cameras at most big events now, which has quietly removed several of the human targets that featured in the older stories. There are fewer people to hit. There is still a crowd.

What you will notice from now on

Shanghai began on Wednesday, and Medvedev is in the draw as the fifth seed, which means he will walk out in front of a very large Chinese crowd a few days after the worst evening of his season. Whatever else that produces, he is not going to touch a loose ball.

Watch for it, now that you know. Watch what the top players do with the spare ball after a point goes against them. The good ones have trained the reflex out: they catch it, or they let it run, or they tap it along the ground towards the ball kid with the care of someone handling something hot. Watch the ones who have not. There is a small flick of the wrist, a ball sent somewhere nobody is looking, and a crowd that claps because they think it is frustration rather than a coin flip.

Most of the time nothing happens. The ball hits the backdrop, or the netting, or an empty seat, and the match carries on and nobody writes anything down. That is the part the rule is really about. Officials are not punishing the consequence so much as the roll of the dice, and they only ever get to punish the rolls that come up badly.

There is a man in Beijing today with a sore eye who went to a tennis match on Monday to watch two of the best players alive, and went home early with a story he would rather not have. Medvedev will send him something, probably, and mean it. The rule exists so there are not more of him.
