Quick Comparison
| Type | Timing |
|---|---|
| Walkover | Before start |
| Forfeit | After start |
| Retirement | Mid-match |
You watch a big match on TV. The players are warming up. Then, suddenly, the announcer says one player won by "walkover." You might wonder: Did they play? Did someone quit mid-game? Or is it something else entirely?
It’s easy to get confused. In sports like boxing or MMA, a "walkover" usually means one fighter didn’t show up. In tennis, it’s similar but has specific rules attached to it. Understanding this term helps you follow tournaments better, especially when injuries or last-minute withdrawals shake up the bracket.
The Simple Definition of a Walkover
A walkover is a victory awarded to a player because their opponent failed to appear for the match or withdrew before the first point was played.
In plain English: If Player A is scheduled to play Player B, and Player B does not show up (or pulls out right before the match starts), Player A wins automatically. No ball is hit. No score is recorded. It’s an administrative win.
This is different from a forfeit. A forfeit happens during a match if a player quits after play has started. A walkover happens *before* play begins. This distinction matters for statistics, rankings, and how fans talk about the result.
Walkover vs. Forfeit vs. Retirement
These three terms often get mixed up. Here’s how to tell them apart:
| Outcome | When It Happens | Score Recorded? | Impact on Stats |
|---|---|---|---|
| Walkover (WO) | Before the match starts | d>No (automatic win)Not counted as a match played | |
| Forfeit | During the match (after start) | Yes (current score stands) | Counted as a loss for the quitter |
| Retirement | During the match (due to injury/fatigue) | Yes (match ends early) | Counted as a loss for the retiree |
If Novak Djokovic shows up and Carlos Alcaraz doesn’t, that’s a walkover. If they start playing, and Alcaraz gets hurt after two sets, that’s a retirement. If Alcarez argues with the umpire and leaves the court in anger, that’s a forfeiture. The timing changes everything.
Why Do Walkovers Happen?
Walkovers are rare in top-level professional tennis, but they do occur. Here are the most common reasons:
- Injury: A player twists an ankle in practice or feels unwell hours before the match. They can’t risk worsening the injury, so they withdraw.
- Illness: Flu, food poisoning, or other sudden health issues can sideline a player.
- Travel Issues: Missed flights, visa problems, or lost luggage can prevent a player from reaching the tournament on time.
- Personal Reasons: Family emergencies or mental health breaks may lead to a last-minute withdrawal.
- Administrative Errors: Rarely, a scheduling mistake or wrong entry in the draw causes confusion, leading to a default walkover.
In Grand Slams like Wimbledon or the US Open, organizers try to avoid walkovers by having alternate players ready. But in smaller tournaments or lower-tier events, a walkover is more likely because there’s no backup pool.
How Walkovers Affect Rankings and Statistics
This is where it gets interesting. When a player wins by walkover, does it count toward their record?
No. According to ATP and WTA rules, a walkover is not considered a match played. That means:
- The winner does not get ranking points for the match.
- The loser does not lose ranking points (since they never competed).
- The win is not added to the winner’s career stats.
- The loss is not added to the loser’s career stats.
Think of it like this: If you’re supposed to run a race, but your competitor doesn’t show up, you don’t get credit for beating them. You just advance to the next round. The same logic applies in tennis.
However, advancing in the tournament still matters. If you win by walkover in Round 1, you move to Round 2. If you then win that match, you earn points for Round 2. So while the walkover itself doesn’t give points, it opens the door to future earnings and ranking opportunities.
Famous Walkovers in Tennis History
While uncommon, some walkovers have made headlines. Here are a few notable examples:
- Roger Federer vs. Andy Murray (2019 Australian Open): Murray withdrew due to back pain before their quarterfinal match. Federer advanced via walkover. He went on to reach the final.
- Simona Halep vs. Karolina Pliskova (2018 French Open): Pliskova pulled out due to illness. Halep moved forward without playing a point.
- Novak Djokovic vs. Stefanos Tsitsipas (2021 US Open): Tsitsipas withdrew due to injury. Djokovic advanced to the semifinals via walkover.
In each case, the winning player was criticized by some fans for not earning the victory. But others argued that getting injured or sick is part of the sport, and the system handles it fairly.
What Happens After a Walkover?
Once a walkover is declared, the remaining player moves to the next round. The tournament schedule adjusts accordingly. Sometimes, this creates odd matchups later in the event, especially if both finalists reached the end via walkovers.
Organizers also review whether the withdrawal was justified. If a player frequently withdraws without valid reason, they may face fines or penalties from the tour. But genuine injuries or illnesses are respected.
In team competitions like the Davis Cup or Billie Jean King Cup, walkovers can have bigger consequences. Since teams rely on individual matches, losing a key player to a walkover can shift the entire outcome of the tie.
Can a Player Challenge a Walkover Decision?
Generally, no. Once the chair umpire or tournament official declares a walkover, it’s final. Players can appeal only if there was a clear error-like being told the match was canceled when it wasn’t.
But here’s a tricky situation: What if a player arrives late? If they miss the warm-up window (usually 10 minutes before the match), they may be defaulted. That’s not technically a walkover-it’s a forfeit due to tardiness. The difference is subtle but important.
Walkovers in Amateur and College Tennis
In college tennis (NCAA) or high school leagues, walkovers are more common. Why? Because student-athletes balance academics, travel, and competition. A missed bus or exam conflict can lead to a walkover.
College tournaments often have stricter deadlines. If a player isn’t checked in by a certain time, they’re out. This reduces chaos but can feel harsh to young athletes.
In recreational play, walkovers are informal. If your friend cancels last minute, you just play someone else. No records are kept. But in competitive circuits, every decision is documented.
How to Prepare for the Possibility of a Walkover
If you’re a fan, expect occasional surprises. Check the tournament website or app for real-time updates. If a player withdraws, the schedule will reflect it quickly.
If you’re a player, always have a backup plan. Train smart, manage recovery, and communicate with coaches and doctors early if you feel off. Preventing a walkover is better than dealing with its aftermath.
And remember: A walkover isn’t a failure. It’s a recognition that sometimes, life interferes with sport. The game continues, and the next match awaits.
Does a walkover count as a win in tennis?
No. A walkover is not counted as a match played. The winner advances but receives no ranking points or statistical credit for the match.
What is the difference between a walkover and a retirement?
A walkover occurs before the match starts. A retirement happens during the match, usually due to injury or fatigue. Retirements are recorded in stats; walkovers are not.
Can a player lose by walkover?
Technically, yes-but it doesn’t count against their record. The player who fails to appear loses the match administratively, but no loss is added to their career stats.
Do walkovers happen in Grand Slam tournaments?
Rarely. Grand Slams have large fields and alternates, so they minimize walkovers. But they can still occur due to sudden injuries or illness.
Is a walkover the same as a default?
Not exactly. A default usually refers to a player failing to meet conduct or attendance rules (like arriving late). A walkover is specifically about non-appearance before play begins. Both result in automatic advancement for the opponent.
How often do walkovers occur in professional tennis?
Very infrequently. Most matches are played out. Walkovers represent less than 1% of all professional matches annually, according to ATP/WTA data.
What happens if both players fail to show up?
This is extremely rare. In such cases, the tournament committee decides based on eligibility, seedings, or alternates. Usually, neither player advances unless special circumstances apply.
Can a coach request a walkover?
Yes. Coaches can notify officials on behalf of a player if the athlete is unable to compete. Medical documentation is often required for legitimacy.
