You've settled into your seat, overpriced soda in hand, ready to watch a heavyweight clash under the stadium lights. The umpire climbs the chair. The crowd hushes. Then, an announcement crackles over the PA system: one of the players has withdrawn. The match is cancelled. Your favorite star advances without hitting a single ball.
That is a walkover.
It’s one of the most anti-climactic moments in sports, yet it’s a fundamental part of how tennis tournaments function. In a sport where physical endurance is pushed to the absolute limit, the walkover is the ultimate safety valve—or, for some fans, a massive frustration.

What is Walkover in Tennis? The Formal Definition
Basically, a walkover (often abbreviated as W/O on scoreboards) occurs when a player advances to the next round because their opponent cannot start the match. The key word here is start.
If the players are on the court and the chair umpire calls "Time" to begin the warm-up, but someone pulls a muscle before the first serve is struck? Still a walkover. But the moment that first serve is hit? Everything changes. From that point on, it’s a retirement.
Honestly, the distinction feels like hair-splitting to a casual observer, but for the record books and the betting window, that single serve is a legal cliff.
According to the ATP and WTA rulebooks, a walkover is officially recorded when the "losing" player is ill, injured, or facing a code of conduct penalty that prevents them from even stepping onto the court. It’s an administrative win, not a competitive one.
The "Invisible" Win: Does it Count for Rankings?
You’d think a win is a win, right? Not exactly.

Tennis is obsessed with data, and walkovers are treated like ghosts in the machine.
- Win-Loss Records: A walkover does not count toward a player’s official win-loss record. If Novak Djokovic gets a walkover in the quarterfinals, his career win tally doesn't go up by one. It’s as if the match never happened in the eyes of the statisticians.
- Head-to-Head: If you're looking at the rivalry between two players, a walkover won't show up in their head-to-head (H2H) stats.
- Ranking Points: This is where it gets interesting. Usually, the player who advances gets the ranking points for the round they just "won." However, there's a catch. On the WTA Tour, if you receive a walkover in the very first round without having played a single point in the tournament, you might not get those points. The logic is simple: you haven't actually "competed" in the event yet.
Walkover vs. Retirement vs. Default
People mix these up all the time. Let’s clear the air.
Retirement is the mid-match exit. Think of a player trailing 4-1 in the second set who suddenly clutches their hamstring and shakes hands. That counts as a "real" loss for them and a "real" win for the opponent.
Default is the "bad boy" category. This is when the supervisor disqualifies a player for breaking the rules. The most famous recent example? Novak Djokovic at the 2020 US Open. He accidentally hit a line judge with a ball and was booted from the tournament. That wasn't a walkover because he was actively playing the match when the incident happened.
Withdrawal is the umbrella term. Every walkover is a withdrawal, but not every withdrawal is a walkover. If a player pulls out three days before the tournament starts, the organizers just move a "Lucky Loser" into their spot. A walkover only happens once the draw is set and the schedule is fixed.
Famous Walkovers That Changed History
Usually, walkovers happen in the early rounds of small tournaments in places like Montpellier or Doha. But sometimes, they wreck the biggest stages in the world.
Rafael Nadal at Wimbledon 2022
This was heartbreaking. Nadal had just survived a brutal five-set quarterfinal against Taylor Fritz, playing through a visible abdominal tear. The world was waiting for a blockbuster semifinal against Nick Kyrgios. Instead, Nadal had to call a press conference the night before to announce he couldn't serve. Kyrgios got a walkover straight into his first Grand Slam final.
The 2014 ATP Finals Fiasco
Imagine paying hundreds of pounds for a ticket to see Roger Federer vs. Novak Djokovic in the final of the year-end championships in London. Federer walked out onto the court—not in his tennis gear, but in a tracksuit—to apologize to the crowd. A back injury meant he couldn't play. It was the first time in the tournament’s 45-year history that the final ended in a walkover.
To save the night, Andy Murray (who wasn't even in the final) rushed to the stadium to play an exhibition match against Djokovic just so the fans had something to watch.
What Happens to Your Money? (The Betting Angle)
If you’ve got skin in the game, a walkover is usually a "push."
Most sportsbooks follow a strict "one-point" or "one-set" rule. Because a walkover happens before a single ball is served, the match is effectively treated as if it were cancelled. Your stake is typically refunded.
However, if you bet on a player to win the entire tournament and they get a walkover in the semis, your bet stays alive. They advanced! You're one step closer to a payout, even if they didn't have to sweat for it. Just be careful—if your player is the one who gives the walkover, your "To Win Tournament" bet is usually a loser.

Why Do They Even Happen?
It’s easy to call modern players "soft," but the tour schedule is a grind. These athletes are playing 11 months a year.
Most walkovers are a result of:
- Acute Injury: A late-night practice session gone wrong or a lingering issue that flared up during warm-ups.
- Illness: Food poisoning is a weirdly common culprit on the pro tour.
- Strategic Preservation: If a player has a minor strain and a Grand Slam is starting the following week, they might give a walkover in a smaller tune-up event to avoid a season-ending tear.
Summary of Actionable Insights for Fans
If you're a hardcore fan or a bettor, keep these nuances in mind next time you see "W/O" on your live-score app:
- Check the "Lucky Loser" Rules: If a player withdraws early enough, they are replaced. If it's too late for a replacement, it's a walkover. Knowing the "order of play" release time helps you predict which one it will be.
- Watch the Warm-up: In some smaller tournaments, if a player looks lethargic or skips the pre-match practice, a walkover might be imminent.
- Don't count it for H2H: If you're arguing with friends about who is better between Sinner and Alcaraz, remember that walkover "wins" don't prove anything on court.
- Betting Refunds: Always check your specific sportsbook’s "House Rules" on tennis. Some require one full set to be completed for a bet to stand; others just need one serve. For a walkover, though, the vast majority will simply give you your money back.
The walkover is a reminder that in tennis, the toughest opponent isn't always the person across the net. Sometimes, it's the player's own body.
