The Serve
The word “love” in tennis scoring almost certainly doesn’t come from the French word for egg. That’s the story everyone tells, and it’s probably wrong. Etymologists have been fighting about it for over a century, with the leading theory now pointing to the English phrase “for love,” meaning “for nothing.” I bring this up because tennis is a sport where even the most basic, universally accepted facts tend to dissolve when you look at them closely. That’s what makes it such perfect trivia territory. People who watch tennis know a lot. They’re just confidently wrong about specific things, and those are the cracks these questions live in.
This set of tennis trivia is built for people who actually follow the sport. Some of these will feel like layups. Some will make you stare at the ceiling. A few might start an argument you won’t finish tonight.
1. What surface was the Australian Open played on before it switched to hard courts in 1988?
Everyone pictures Melbourne’s blue hard courts and assumes that’s always been the deal. It hasn’t. And the surface it used to be played on is the one most people associate with a completely different Slam.
Show Answer
Grass. The Australian Open was played on grass courts at Kooyong until the move to Melbourne Park and Rebound Ace hard courts in 1988. Most people guess clay, which is interesting because it reveals they’re thinking of the French Open and just picking the leftover surface.
2. How many Grand Slam singles titles did Roger Federer win?
This one’s a temperature check. If you get this wrong, buckle up.
Show Answer
20. He held the all-time record until Nadal passed him with 21 at the 2022 Australian Open, and then Djokovic passed them both.
3. In tennis scoring, what comes after 30?
I’ve used this as a first question at events and watched someone shout “35” with total conviction. The scoring system is so ingrained that people stop actually thinking about it.
Show Answer
40. Not 45, which is what the pattern would logically suggest. The jump from 30 to 40 (instead of 45) likely happened because “forty” was easier to call out than “forty-five” in medieval jeu de paume.
4. Which Grand Slam is played on red clay?
Gimme. But it sets up harder ones later.
Show Answer
The French Open (Roland-Garros).
5. What country is Rafael Nadal from?
I include this because at a pub quiz in Austin, someone once said “Portugal” and the table erupted. Some questions exist just to keep the energy moving.
Show Answer
Spain. He’s from Manacor, Mallorca, specifically.
6. What is the only Grand Slam tournament that’s still played on grass?
Show Answer
Wimbledon. It’s the oldest tennis tournament in the world, running since 1877, and the grass is perennial ryegrass cut to exactly 8mm.
7. Who holds the record for the most Grand Slam men’s singles titles as of 2024?
This one used to be a fight. It’s not anymore.
Show Answer
Novak Djokovic, with 24. The number that sticks in people’s heads is often 21 (Nadal’s count when he briefly held the record) or 20 (Federer’s). The record changed hands three times in about eighteen months.
8. What do players traditionally wear at Wimbledon?
Simple question, but the specifics trip people up. They know the color. They don’t always know how strict the rule actually is.
Show Answer
Predominantly white clothing. Wimbledon’s dress code requires “almost entirely white” attire, and they enforce it down to the color of undergarments and shoe soles. Players have been asked to change mid-match.
Where Confidence Goes to Die
9. Which female tennis player has won the most Grand Slam singles titles in the Open Era?
This is where the room splits. Half say one name, half say another, and both groups are sure.
Show Answer
Margaret Court holds the all-time record with 24 Grand Slam singles titles, but only 11 came in the Open Era. Serena Williams holds the Open Era record with 23. The common wrong answer is Steffi Graf (22), who people confuse with the all-time leader because of the calendar-year Golden Slam narrative.
10. What does it mean to win a “Golden Slam”?
Most tennis fans know this term. But I’ve found that about a third of them define it wrong.
Show Answer
Winning all four Grand Slam tournaments AND the Olympic gold medal in singles in the same calendar year. Steffi Graf is the only player in history to achieve this, doing it in 1988. A common wrong answer is simply winning all four Slams in a year, which is a Calendar Grand Slam, not a Golden Slam.
11. What is the name of the trophy awarded to the Wimbledon men’s singles champion?
People know the women’s trophy has a name. The men’s trophy? That’s where it gets quiet.
Show Answer
The Challenge Cup (or the Gentlemen’s Singles Trophy). Most people can’t name it because it’s almost never referred to by name in broadcasts. The women’s trophy, the Venus Rosewater Dish, gets named constantly.
12. How many sets does a player need to win to take a men’s singles match at a Grand Slam?
Show Answer
Three sets (best of five). Women’s Grand Slam singles matches are best of three. This disparity has been one of the sport’s longest-running debates.
13. What is a “bagel” in tennis slang?
Non-tennis people find this one delightful. Tennis people sometimes overthink it.
Show Answer
Winning (or losing) a set 6-0. The zero looks like a bagel. Losing a match 6-0, 6-0 is sometimes called a “double bagel,” which is the kind of humiliation that follows a player for years.
14. Which player served the fastest recorded serve in professional tennis history?
There’s a name everyone guesses first, and it’s wrong. The actual record holder is someone most casual fans have barely heard of.
Show Answer
Sam Groth, who hit a serve measured at 163.7 mph (263.4 km/h) in 2012. However, the ATP officially recognizes John Isner’s 157.2 mph serve as the record because Groth’s was recorded at a Challenger event with different radar technology. The common wrong guess is Andy Roddick, whose 155 mph serve held the record for years and lodged itself in everyone’s memory.
15. What does “AD” stand for in tennis scoring?
Show Answer
Advantage. After deuce (40-40), the next point gives one player the advantage. If they win the following point, they win the game. If they lose it, it goes back to deuce.
16. In what city is the French Open held?
I know. But you’d be surprised how often “Lyon” or “Nice” comes up.
Show Answer
Paris. The tournament is held at Stade Roland-Garros in the 16th arrondissement.
17. Who was the last man to win a Calendar Grand Slam (all four majors in the same year)?
This question reveals something interesting about how we remember greatness. Everyone assumes it must be one of the Big Three. It’s not even close.
Show Answer
Rod Laver, in 1969. He also did it in 1962. No man has managed it since, despite Djokovic coming agonizingly close in 2021 (he lost the US Open final to Medvedev). The fact that neither Federer, Nadal, nor Djokovic achieved it tells you something about how hard it actually is.
18. What year did tennis return to the Olympic Games as a full medal sport?
This one stumps almost everyone. Tennis was in the early Olympics, got dropped, and came back. But the year it came back? Blank stares.
Show Answer
1988, at the Seoul Olympics. Tennis had been a medal sport from 1896 to 1924, was dropped, had a demonstration event in 1984, and returned fully in 1988. Steffi Graf won that first women’s singles gold on her way to the Golden Slam.
19. What is the term for winning a game in which your opponent is serving?
Show Answer
A break (or a service break). Breaking serve is one of the most pivotal moments in any match, and on fast surfaces it can be the only one that matters.
20. Who is the youngest player to ever be ranked World No. 1 in men’s singles?
The instinct is to say someone from the current generation. The answer is older than most people expect.
Show Answer
Carlos Alcaraz? No. It’s Lleyton Hewitt, who reached No. 1 in November 2001 at age 20 years and 275 days. Alcaraz actually broke this record in 2022 at 19 years and 130 days. So the answer depends on when you last checked. As of 2024, it’s Alcaraz. I’ve seen this question generate arguments because people remember Hewitt’s record and don’t realize it was broken.
The Net Gets Higher
21. What is the height of a tennis net at its center?
Players who’ve played their whole lives get this wrong. It’s lower than people think.
Show Answer
3 feet (0.914 meters) at the center. It’s 3 feet 6 inches at the posts. The sag in the middle is held down by a center strap, and that six-inch difference changes the geometry of every crosscourt shot.
22. What tournament is known as “The Fifth Slam”?
There’s only one correct answer, but I’ve heard three different tournaments argued for this title at the same table.
Show Answer
The Indian Wells Masters (BNP Paribas Open), held in Indian Wells, California. It earns the nickname through its prestige, two-week duration, and the depth of its draw. Some people argue for the ATP Finals or the Miami Open, but Indian Wells owns the nickname.
23. Before Naomi Osaka, who was the last Asian-born player to win a Grand Slam singles title?
This one goes quiet in a room. People cycle through names and come up empty.
Show Answer
Li Na, who won the 2011 French Open and the 2014 Australian Open. She was the first Asian-born player to win a Grand Slam singles title, and Osaka (born in Japan, raised in the US) followed. The silence this question creates is because most people can’t name a single Asian Grand Slam champion before Osaka.
24. What does “WTA” stand for?
Show Answer
Women’s Tennis Association. Founded in 1973 by Billie Jean King and others, partly in response to prize money disparities.
25. In the famous “Battle of the Sexes” match in 1973, Billie Jean King defeated which male player?
Most people know this happened. The name of the man she beat is where it gets fuzzy.
Show Answer
Bobby Riggs. He was 55 years old at the time and had previously beaten Margaret Court. King won in straight sets in front of roughly 90 million television viewers worldwide. The common wrong answer is John McEnroe, which is completely wrong era but reveals how much that name dominates people’s image of theatrical tennis moments.
26. What Grand Slam tournament did Serena Williams win the most times?
This requires you to know her Slam breakdown, not just the total. And the answer isn’t the one most Americans guess first.
Show Answer
The Australian Open, with 7 titles. She also won Wimbledon 7 times, so both are technically correct. But the US Open, which Americans tend to guess because of the home-crowd narrative, she won 6 times. The French Open was her lowest tally with 3.
27. What year was the first Wimbledon Championship held?
People know it’s old. They rarely know how old.
Show Answer
1877. Only men’s singles was contested that first year. Women’s singles wasn’t added until 1884. The tournament predates the modern Olympic Games by 19 years.
28. What is the longest match in tennis history by duration?
Everyone who follows tennis knows this one, but the specific details still stagger.
Show Answer
John Isner vs. Nicolas Mahut at Wimbledon in 2010, lasting 11 hours and 5 minutes across three days. The final set alone was 8 hours and 11 minutes, finishing 70-68. The match was so long it broke the scoreboard.
29. Which player was nicknamed “The Punisher”?
This is a trap. The nickname sounds like it should belong to someone aggressive and famous. It doesn’t.
Show Answer
David Nalbandian. The Argentine was known for grinding down opponents with relentless baseline play. Most people guess someone like Nadal or Djokovic, whose playing styles better fit the image the nickname conjures.
30. How many times did Bjorn Borg win Wimbledon consecutively?
Borg’s Wimbledon run is one of those stats that sounds made up when you hear it for the first time.
Show Answer
Five consecutive Wimbledon titles (1976-1980). He then lost the 1981 final to John McEnroe and retired from the sport at age 26, which might be the most stunning part of the whole story.
Rallies That Go Long
31. What fruit is on top of the Wimbledon men’s singles trophy?
I love this question because it exposes whether someone has actually looked at the trophy or just seen it hoisted from a distance on TV.
Show Answer
A pineapple. It’s been there since 1887, and it’s thought to represent hospitality, which was a common association with pineapples in Victorian England. Almost everyone guesses a tennis ball, which would be absurdly on-the-nose for something that old.
32. What does it mean when a player hits a “tweener”?
Show Answer
A shot hit between the legs, usually while running away from the net. It’s become a highlight-reel staple, but Roger Federer hitting one against Novak Djokovic at the 2009 US Open might be the single most replayed shot in modern tennis history.
33. Which country has won the most Davis Cup titles?
The Davis Cup is old enough and obscure enough that this becomes a genuine guessing game. I’ve seen Americans guess the US, Europeans guess their own countries, and everyone forgets the actual answer.
Show Answer
The United States, with 32 titles. Australia is second with 28. People often guess Spain or Switzerland because of the dominance of Nadal and Federer, but the Davis Cup’s history stretches back to 1900 and the US dominated the early decades.
34. What is a “let” in tennis?
Show Answer
A serve that clips the top of the net but still lands in the correct service box. The point is replayed. There’s no limit to the number of lets that can occur on a single point, and some experimental rule changes have tried to eliminate the let entirely.
35. Which Grand Slam was the last to adopt a tiebreak in the final set?
This changed recently enough that a lot of fans still have the old rules in their heads.
Show Answer
Wimbledon, which introduced a final-set tiebreak at 12-12 in 2019, then switched to a first-to-10 super tiebreak at 6-6 in 2022. The French Open was the last holdout in some tellings, adopting a super tiebreak at 6-6 in the final set starting in 2022. The timeline is messy, which is why this question generates so much debate.
36. Who coached Serena Williams for most of her career?
Everyone knows the name. Not everyone realizes what makes the answer remarkable.
Show Answer
Her father, Richard Williams. He had no formal tennis training and learned the sport from books and videos before coaching both Venus and Serena from childhood in Compton, California. Patrick Mouratoglou coached her from 2012 onward, but Richard built the foundation for the greatest career in women’s tennis.
37. What is the diameter of a regulation tennis ball?
Nobody knows this. I mean nobody. But people guess with incredible confidence.
Show Answer
Between 2.57 and 2.70 inches (6.54-6.86 cm). The range itself surprises people, who assume there’s one exact measurement. A tennis ball is slightly larger than most people’s mental image of it when they’re forced to commit to a number.
38. Andre Agassi famously revealed in his autobiography that he wore what during his early career?
If you know, you know. If you don’t, the answer is genuinely funny.
Show Answer
A wig. His iconic mullet-era hair was fake, and he wrote about the anxiety of it potentially falling off during matches. He lost the 1990 French Open final and later said part of his distraction was worrying about his hairpiece. When he finally shaved his head, he started playing some of the best tennis of his career.
39. What is the term for four consecutive Grand Slam wins that span two calendar years?
This is a precision question. People know the concept but fumble the name.
Show Answer
A Non-Calendar Year Grand Slam, sometimes called a “Serena Slam” because Serena Williams accomplished it by winning the 2002 French Open through the 2003 Australian Open. Djokovic also held all four simultaneously in 2015-2016. It’s not called a Grand Slam proper because the wins don’t occur in the same calendar year.
40. What color are the tennis balls used at Wimbledon?
This is a trick question disguised as the easiest question in the set. And I promise you, it starts arguments.
Show Answer
Optic yellow (officially). Not green. The International Tennis Federation specifies the color as yellow, and Wimbledon uses Slazenger balls that are optic yellow. Roger Federer once said they were yellow. The internet has been fighting about whether tennis balls are green or yellow since 2018, and this question reliably divides any room in half.
Second Serve
41. Which female player completed the Career Golden Slam (all four majors plus Olympic gold, not necessarily in one year)?
There are fewer names on this list than people think.
Show Answer
Steffi Graf (who did it in a single year, 1988), Serena Williams (completed it at the 2012 Olympics), and Andre Agassi on the men’s side. If the question is specifically about women, Graf and Williams are the only two. Most people forget that Serena’s Olympic gold was in singles at the 2012 London Games.
42. What was the original name for tennis when it was played indoors in medieval France?
This is the kind of question that makes someone at the table say “wait, really?” when they hear the answer.
Show Answer
Jeu de paume, meaning “game of the palm.” Players originally hit the ball with their hands. Rackets weren’t introduced until the 16th century. The name “tennis” likely comes from the French “tenez,” meaning “take” or “receive,” which players called out before serving.
43. Who is the only player to have beaten Nadal in a French Open final?
Nadal’s dominance at Roland-Garros is so total that people sometimes assume he never lost a final there. He did. Once.
Show Answer
Nobody has beaten Nadal in a French Open final. He won all 14 finals he played there. His four losses at Roland-Garros all came before the final round. I wrote this question specifically to catch people who think they remember an upset that never happened. In a room, someone always shouts “Djokovic!” with complete certainty.
44. What does “ATP” stand for?
Show Answer
Association of Tennis Professionals. Founded in 1972, it governs the men’s professional tennis tour.
45. Which tennis player has the most career aces in men’s professional tennis?
The serve specialists don’t get enough love. This question is for them.
Show Answer
Ivo Karlovic, with over 13,700 career aces. The Croatian was 6’11” and basically played a different sport than everyone else. John Isner is close behind. Neither ever won a Grand Slam title, which tells you something about how much more there is to tennis than serving.
46. What is the only Grand Slam where the men’s and women’s singles champions receive equal prize money and have since 2001?
The timeline on equal prize money across the Slams is more complicated than people realize.
Show Answer
The Australian Open has offered equal prize money since 2001. The US Open was actually first, starting equal pay in 1973, but the question specifies “since 2001” as a continuous modern benchmark. Wimbledon didn’t achieve equal prize money until 2007, and Roland-Garros followed in 2006. The common wrong answer is the US Open, which is understandable given its longer history of equal pay, but the question’s framing matters.
47. What is the term for winning a set 6-1?
If you got the bagel question earlier, this one’s a layup. If you didn’t, you’re about to learn a second food term.
Show Answer
A breadstick. The “1” on the scoreboard looks like a breadstick. Tennis commentary has a whole bakery’s worth of terminology, and once you learn these two, you’ll hear them constantly.
48. Monica Seles was infamously stabbed during a match in 1993. Who was her opponent at the time?
Everyone remembers the stabbing. Almost nobody remembers the match itself, because the match stopped being the point the moment it happened.
Show Answer
Magdalena Maleeva. Seles was attacked by a spectator named Günter Parche during a changeover at a tournament in Hamburg. The attacker was a fan of Steffi Graf who wanted Graf to regain the No. 1 ranking. Seles didn’t return to competitive tennis for over two years. The fact that Parche received a suspended sentence and never served prison time remains one of the most infuriating details in sports history.
49. How many Grand Slam titles did Pete Sampras retire with, and how long did his record last as the all-time men’s leader?
Sampras held the throne for what felt like forever. In reality, it was a very specific number of years, and the man who broke it did so in the most Pete Sampras place imaginable.
Show Answer
14 Grand Slam titles. His record stood for nearly seven years, from his final title at the 2002 US Open until Roger Federer won his 15th at Wimbledon in 2009. Sampras was in the stands that day. He stood and applauded.
Match Point
50. In the 2008 Wimbledon final between Nadal and Federer, often called the greatest match ever played, what was the score of the final set?
If you watched it, you remember the rain delays, the fading light, Federer saving match points, and the feeling that neither player deserved to lose. The specific score of that final set is the detail that separates people who watched it from people who’ve read about it. I’ve ended trivia nights on this question because it doesn’t just test knowledge. It tests whether you were there, in whatever room you were in, when it happened. And the people who remember the score always remember it with something in their voice that goes beyond tennis.
Show Answer
9-7 in the fifth set, Nadal winning. The full score was 6-4, 6-4, 6-7(5), 6-7(8), 9-7. It ended in near-darkness at 9:15 PM London time. John McEnroe called it the greatest match he had ever seen. It was the match that proved Nadal could beat Federer on grass, and it broke something open in the rivalry that never quite closed.
I've been the sports round writer for quiz leagues in Portland, OR for 10 years, which means I've learned exactly which questions make the football fans groan and which ones catch everyone off guard.
