ATP career statistics updated for 2026
Some points in tennis require twenty shots.
An ace requires one.
The ball leaves the server’s racket, travels across the net and lands legally in the service box.
The returner never touches it.
Point over.
No rally.
No second shot.
No opportunity to recover.
Across an entire professional career, those instant points can accumulate into astonishing numbers.
John Isner produced more than:
14,000 of them.
Ivo Karlovic came close to the same territory.
Roger Federer exceeded 11,000 despite building his serving reputation more around disguise and placement than extreme height.
Feliciano Lopez and Goran Ivanisevic both crossed 10,000.
And several other legendary servers accumulated more than 8,000 career aces.
According to the ATP’s recorded career statistics, the men’s leader is:
John Isner — 14,470 career aces.
That is the official benchmark in the ATP statistical era.
But the leaderboard reveals much more than who hit the biggest number.
Why did Isner eventually pass Karlovic?
How did Federer reach third without possessing one of the fastest serves ever recorded?
Why is Pete Sampras below players who won far fewer major titles?
And why can’t we fairly compare these totals with every great server from the 1960s, 1970s or 1980s?
The answers show why an ace is one of tennis’s simplest statistics — and one of its most interesting.
Who Has Hit the Most Aces in Tennis History?
According to the ATP’s career ace statistics, John Isner holds the men’s record with 14,470 aces.
The current leading group is:
| Rank | Player | Career Aces |
|---|---|---|
| 1 | John Isner | 14,470 |
| 2 | Ivo Karlovic | 13,728 |
| 3 | Roger Federer | 11,478 |
| 4 | Feliciano Lopez | 10,261 |
| 5 | Goran Ivanisevic | 10,237 |
| 6 | Andy Roddick | 9,074 |
| 7 | Sam Querrey | 8,879 |
| 8 | Pete Sampras | 8,858 |
| 9 | Marin Cilic* | 8,580 |
| 10 | Milos Raonic | 8,445 |
*Cilic remains active in 2026, so his total can still increase.
Isner leads Karlovic by:
742 aces.
He finished almost:
3,000 ahead of Federer.
But before interpreting those totals, there is an important statistical limitation to understand.
An Important Note About Tennis Ace Records
ATP match-stat tracking begins in:
1991.
That means the career leaderboard should really be understood as:
the ATP recorded-era career ace leaderboard.
It does not give us a complete point-by-point ace count for every great server who competed before 1991.
That matters when discussing legends such as:
Pancho Gonzales,
John Newcombe,
Rod Laver,
Arthur Ashe,
and other earlier champions.
They may have hit enormous numbers of aces.
We simply do not possess the same complete statistical database for their careers.
So when this article says:
John Isner holds the record
it refers to the official ATP statistical record.
That is a much more accurate claim than pretending every serve in 100+ years of professional tennis was measured identically.
What Is an Ace in Tennis?
An ace occurs when:
a legal serve lands in the correct service box and the receiver does not touch the ball.
The server wins the point immediately.
If the returner touches the ball but cannot put it back into play, the point may be recorded as a:
service winner
rather than an ace.
That distinction matters statistically.
Why Aces Are So Valuable
An ace removes almost every variable from the point.
The server does not have to:
hit a forehand,
play defense,
approach the net,
win a long rally,
or respond to the opponent.
The point ends immediately.
That creates several advantages.
Free Points
The obvious benefit.
No rally is required.
Energy Conservation
Short service points reduce physical workload across long matches and tournaments.
Scoreboard Pressure
A player facing repeated aces may feel there are very few opportunities to break serve.
Confidence
A server who knows he can produce an ace at an important moment can play more aggressively.
But a high ace total alone does not necessarily mean a player had the greatest serve.
We will return to that distinction later.
John Isner — 14,470 Career Aces
John Isner sits at the top of the ATP career leaderboard with:
14,470 aces.
His serve shaped almost every part of his career.
At approximately 6-foot-10, Isner struck the ball from an exceptionally high contact point.
That gave him:
power,
angle,
and margin over the net.
The combination made breaking his serve extremely difficult.
Why Isner Was Built for Ace Production
Height was only part of the equation.
Isner also possessed:
a powerful leg drive,
clean serving mechanics,
excellent placement,
a dangerous kick serve,
and the confidence to hit aggressively on big points.
His first serve could simply overpower opponents.
His second serve could jump high enough to make aggressive returning difficult.
That made him much more than a player trying to hit the radar gun.
Isner’s 113-Ace Wimbledon Match
One match captures Isner’s serving career better than any other.
Wimbledon.
John Isner vs Nicolas Mahut.
The match lasted:
11 hours and 5 minutes.
It required:
three days.
The fifth set ended:
70–68.
And Isner hit:
113 aces.
That remains an extraordinary single-match serving record.
If you want the full story, read our guide to the longest tennis match ever.
113 Aces in One Match
Consider the scale.
Many professional players do not hit 113 aces across an entire tournament.
Isner did it against:
one opponent.
Mahut himself hit:
103.
The two combined for:
216 aces.
The match became the ultimate demonstration of what happens when two elite servers repeatedly protect their service games and the rules allow the deciding set to continue without an early tiebreak.
Ivo Karlovic — 13,728 Aces
Before Isner took over, the career record belonged to:
Ivo Karlovic.
Final total:
13,728 aces.
Karlovic stood approximately:
6-foot-11 — 2.11 meters.
His height gave him perhaps the most naturally intimidating service geometry professional tennis has seen.
Karlovic’s Contact Point Changed the Return
A returner normally has several cues to read.
With Karlovic, another problem appeared:
the ball was coming from an extraordinary height.
That altered:
trajectory,
bounce,
angle,
and reaction time.
A serve down the T could arrive quickly.
A wide serve could pull a returner completely outside the court.
And his kick serve could climb dramatically after bouncing.
Karlovic Made Serving the Foundation of an Entire Career
Karlovic never won a Grand Slam singles title.
He never became World No. 1.
Yet his serve allowed him to remain competitive for an exceptionally long time.
That tells us something important.
A historically great weapon can support an entire professional career even when other parts of a player’s game are not at the level of the greatest champions.
Karlovic made:
13,728 aces
one of the defining numbers in serving history.
Isner vs Karlovic: Who Was the Bigger Ace Machine?
Career totals:
Isner — 14,470
Karlovic — 13,728
Isner leads.
But the comparison is closer than the raw ranking suggests.
Both players built their games around:
height,
first-serve power,
difficult serving angles,
and extremely strong service holds.
Karlovic spent years as the record holder.
Isner eventually moved past him and finished with the largest total in ATP history.
Roger Federer — 11,478 Aces
The player in third place looks different from the two giants above him.
Roger Federer finished with:
11,478 career aces.
Federer stood around:
6-foot-1.
He did not rely on overwhelming height.
He did not regularly chase 150 mph serves.
Yet he finished behind only Isner and Karlovic.
That tells us a great deal about what makes an effective serve.
For Federer’s complete career record, visit our Roger Federer profile.
How Did Federer Hit So Many Aces?
Federer’s greatest serving weapon may have been:
disguise.
His ball toss looked similar across different serve locations.
The returner had difficulty determining whether Federer would serve:
wide,
into the body,
or down the T.
By the time the direction became clear, the receiver was already reacting late.
Federer Proved That Placement Can Beat Pure Speed
A serve does not need to be the fastest to become an ace.
Imagine two serves.
Serve A
150 mph directly into the returner’s ideal strike zone.
Serve B
125 mph perfectly placed on the sideline.
Serve B may be much harder to return.
Federer’s career is one of the clearest demonstrations of that principle.
Speed matters.
Precision matters more.
Feliciano Lopez — 10,261 Aces
Feliciano Lopez finished with:
10,261 career aces.
That places him fourth on the ATP leaderboard.
Lopez’s inclusion so high on the list also reflects extraordinary longevity.
He remained on tour for more than two decades and appeared in:
81 Grand Slam main draws.
A Left-Handed Serve Creates Different Problems
Lopez served left-handed.
That naturally changed the geometry of certain service patterns.
A left-hander’s slice serve can drag a right-handed returner particularly wide on one side of the court.
Lopez combined that advantage with:
height,
fluid mechanics,
and attacking instincts.
The result:
more than:
10,000 career aces.
Goran Ivanisevic — 10,237 Aces
Only 24 aces separate Lopez from:
Goran Ivanisevic — 10,237.
Ivanisevic was one of the defining servers of the 1990s.
His left-handed serve could dominate matches.
When his first serve was functioning at its highest level, opponents sometimes had almost no opportunity to establish neutral rallies.
Ivanisevic’s Serve and Wimbledon
No tournament suited Ivanisevic’s weapon better than:
Wimbledon.
Grass rewarded:
fast serving,
short points,
and aggressive first-strike tennis.
Ivanisevic reached the Wimbledon final several times before finally winning the championship in:
2001.
He entered that tournament as a wild card.
His serving remained central to one of the most remarkable title runs in Wimbledon history.
Only 24 Aces Separate Lopez and Ivanisevic
Their career totals:
Lopez — 10,261
Ivanisevic — 10,237
Difference:
24.
That is tiny across careers containing more than 10,000 aces.
The two players reached the number in different ways.
Ivanisevic was a more explosive championship-level server during his peak.
Lopez used exceptional longevity to continue accumulating aces over many seasons.
Again, career totals can tell several different stories.
Andy Roddick — 9,074 Career Aces
Andy Roddick finished with:
9,074 ATP-recorded aces.
His serve may be one of the most recognizable motions in tennis history.
It was compact.
Fast.
Explosive.
There was relatively little wasted movement before the racket accelerated toward the ball.
Roddick Combined Speed With Results
Roddick was not merely a radar-gun attraction.
His serve helped him become:
World No. 1
and:
US Open champion.
He also reached multiple Wimbledon finals.
Roddick’s best first serves travelled well above 140 mph.
But his second serve was also an important weapon.
That combination made him difficult to attack even when the first serve missed.
Roddick and the Fastest-Serve Conversation
For years, Roddick was closely associated with extreme serve speed.
His career high was around:
152 mph.
But that still sits below Sam Groth’s recognized 163.4 mph record.
You can see the full speed comparison in our guide to the fastest tennis serve ever.
That article measures:
maximum speed.
This one measures:
career production.
Roddick is a perfect example of why the two rankings are not identical.
Sam Querrey — 8,879 Aces
Sam Querrey finished with:
8,879 career aces.
The American stood 6-foot-6 and built a game around:
powerful serving,
flat groundstrokes,
and aggressive hard-court tennis.
Querrey may not have reached the career heights of Federer or Sampras.
But when we isolate pure ace production:
he belongs among the greatest statistical servers of the recorded era.
Querrey Also Produced Huge Serving Performances
Querrey could accumulate aces rapidly when his first serve was working.
His height and relatively uncomplicated motion allowed him to generate:
pace
without enormous physical effort on every serve.
That helped him remain dangerous across long matches.
It also contributed to his position near the top of the career leaderboard.
Pete Sampras — 8,858 Aces
Pete Sampras finished with:
8,858 career aces in the ATP recorded statistics.
Only:
21 aces
separate him from Querrey.
But Sampras’s serving legacy cannot be evaluated through career ace totals alone.
Why Sampras May Have Had a Better Serve Than His Ranking Suggests
Sampras owned one of the most feared serves in tennis history.
What made it special was not merely ace production.
It was:
when he could produce his best serve.
Break point.
Tiebreak.
Set point.
Championship point.
Sampras repeatedly found enormous serves under pressure.
Sampras Had an Exceptional Second Serve
Many players reduce risk dramatically on second serve.
Sampras could still attack.
His second serve combined:
pace,
kick,
and exceptional placement.
That made opponents uncomfortable even after the first serve missed.
So while eight players sit above or around him in raw career ace totals, very few would automatically be ranked ahead of Sampras in a debate about:
the greatest serve ever.
Marin Cilic — 8,580 Aces and Counting
As of the current 2026 ATP statistics, Marin Cilic has:
8,580 career aces.
Unlike most of the players above him:
Cilic remains active.
That means this number can still grow.
Why Cilic Is an Important 2026 Update
Static record articles can become inaccurate quickly when active players are involved.
Cilic returned from significant injury problems and continued competing in 2026.
His serve remains one of the foundations of his game.
At 6-foot-6, he can generate:
speed,
steep angles,
and high first-serve effectiveness.
His total has already moved him into the ATP top 10.
Cilic’s Serve Helped Produce a Grand Slam Championship
Cilic’s greatest career achievement came at:
US Open 2014.
His aggressive tennis overwhelmed opponents during the final stages of the tournament.
Serving was central to that success.
He eventually defeated Kei Nishikori in the final and became a Grand Slam singles champion.
So Cilic combines:
elite career ace production
with:
major championship success.
Milos Raonic — 8,445 Aces
Milos Raonic finished his career with:
8,445 aces.
He retired in:
2026.
Raonic reached:
World No. 3
and:
the Wimbledon final.
His serve was the foundation of that rise.
Raonic Was More Than a Power Server
Raonic could serve extremely hard.
But his effectiveness came from combining:
velocity,
placement,
height,
and repetition.
His motion allowed him to reproduce strong serving numbers over many seasons.
That helped him accumulate more than:
8,400 career aces.
The Top 10 Career Ace Leaders Compared
The leaderboard can be grouped into several different types of servers.
The Physical Giants
John Isner
Ivo Karlovic
Sam Querrey
Marin Cilic
Milos Raonic
Height played a major role in creating extreme service angles.
The Left-Handed Servers
Feliciano Lopez
Goran Ivanisevic
Their natural left-handed geometry created different return patterns.
The Precision Server
Roger Federer
Disguise and placement helped him reach 11,478 without relying on extreme height.
The Explosive Power Server
Andy Roddick
One of the fastest and most aggressive service motions of his era.
The Pressure Server
Pete Sampras
Perhaps the clearest example of why career ace totals cannot completely measure serving greatness.
Why John Isner Has More Aces Than Roger Federer
The difference is:
2,992 aces.
That does not mean Isner was a better tennis player.
It means the structure of his game produced more aces.
Several factors helped.
Greater Height
Isner’s contact point created more extreme angles.
More Serve-Dependent Tennis
Isner relied on his serve more heavily than Federer.
More Tiebreak-Oriented Matches
Frequent service holds created long sets and more serving opportunities.
Extremely High Ace Frequency
Isner regularly produced double-digit ace totals.
Federer was a more complete all-court player whose service games did not depend as heavily on aces.
Career Aces vs Fastest Serve
These statistics should never be confused.
Fastest Serve
Measures:
the maximum speed of one serve.
Career Aces
Measure:
how many untouched legal serves a player accumulated across recorded matches.
Sam Groth owns the recognized men’s speed record.
John Isner owns the career ace record.
Different players.
Different achievements.
Career Aces vs Best Serve
There is a third question:
Who had the greatest serve?
That requires much more than counting aces.
We would need to consider:
service games won,
first-serve points won,
second-serve quality,
break points saved,
placement,
double faults,
performance under pressure,
surface adaptability,
and serving against elite returners.
Raw ace totals are valuable.
They are not the whole argument.
Why Federer and Sampras Complicate the Ace Debate
Consider:
Federer — 11,478 aces
Sampras — 8,858
Federer leads by more than:
2,600.
Does that automatically mean Federer had the better serve?
No.
Federer played far more recorded matches.
Sampras retired younger.
Their styles were different.
Their eras were different.
And Sampras’s serving reputation relied heavily on effectiveness during the most important moments.
That’s why counting career totals without context can produce misleading conclusions.
How Does Surface Affect Ace Production?
Not every surface rewards serving in the same way.
Grass
Traditionally favorable to big servers.
The lower, faster bounce reduces return time.
Hard Court
Offers excellent conditions for powerful first serves at many tournaments.
Clay
Generally gives returners more time and produces slower conditions.
A player whose career contains many grass and fast hard-court matches may have more favorable ace conditions than a player whose greatest success comes on clay.
Why Nadal Is Not Near the Top of the Ace Leaderboard
Rafael Nadal won:
22 Grand Slam titles.
Yet his career was not built around ace production.
Nadal’s serve served a different tactical purpose.
It helped begin points in positions that allowed him to use:
his forehand,
movement,
and baseline patterns.
For his complete career, visit our Rafael Nadal profile.
This demonstrates an important point:
aces are one way to win service points — not the only way.
Why Djokovic Does Not Need Isner-Level Ace Numbers
Novak Djokovic is another example.
His career greatness is built heavily around:
returning,
baseline control,
movement,
defense,
and pressure performance.
His serve improved significantly over time.
But Djokovic never needed to become an Isner-style ace machine.
For his complete résumé, visit our Novak Djokovic profile.
Aces Can Reduce Physical Workload
This becomes particularly important during Grand Slam tournaments.
A men’s major champion may need to win:
seven best-of-five matches.
That can create enormous physical demands.
Every ace ends a point immediately.
Imagine Player A must regularly win:
10-shot rallies
to hold serve.
Player B receives several free points every service game.
Across:
three hours,
five sets,
and seven tournament rounds,
that difference can become physically significant.
The Hidden Value of an Ace at 30–30
Not all aces feel equally important.
An ace at:
40–0
is useful.
An ace at:
30–30
may change the entire service game.
An ace facing:
break point
can prevent the opponent from taking control of the set.
That is why raw totals are only the beginning.
Pressure context matters.
Can a Player Hit Too Many Double Faults Chasing Aces?
Yes.
Serving aggressively always involves risk.
A player chasing maximum speed or tiny targets may:
miss more first serves
and:
produce more double faults.
The ideal server finds the correct balance between:
aggression
and:
reliability.
That balance can change based on:
score,
surface,
opponent,
and confidence.
Is an Ace Better Than a Service Winner?
On the scoreboard:
both win one point.
Statistically:
they are classified differently.
An ace means the returner:
does not touch the serve.
A service winner may involve contact but no successful return.
From a tactical perspective, both can represent dominant serving.
That is another reason ace totals do not capture every unreturnable serve.
The 10,000-Ace Club
Only a very small group has crossed:
10,000 ATP-recorded career aces.
They are:
John Isner
Ivo Karlovic
Roger Federer
Feliciano Lopez
Goran Ivanisevic
Five players.
That is one of serving’s most exclusive statistical clubs.
How Difficult Is 10,000 Aces?
Imagine averaging:
10 aces per match.
A player would need:
1,000 matches
to reach 10,000.
Average:
15 per match
and it still requires roughly:
667 matches.
Players therefore need some combination of:
enormous serving frequency,
long careers,
high-level participation,
and relatively good health.
That’s why the milestone is so rare.
Most Aces in One Match vs Most Career Aces
John Isner owns the famous combination:
career ace leader
and:
113 aces in the 2010 Wimbledon marathon.
But single-match and career records reward different things.
A giant one-match total can come from:
an unusually long contest.
A giant career total requires:
years of production.
Isner managed both.
What About Women’s Career Ace Records?
This comparison requires caution.
The WTA’s detailed match-stat era does not cover women’s tennis history in exactly the same way as the ATP career database.
For example, WTA historical statistical material has discussed ace totals during the modern match-stat era and noted Serena Williams as one of the leading ace producers.
But those figures should not simply be placed beside ATP numbers and presented as a complete men-vs-women all-time leaderboard.
The coverage periods are different.
The match formats are different.
The datasets are different.
For this reason, the main leaderboard in this article uses the official ATP men’s career database rather than manufacturing a false cross-tour ranking.
Why Historical Servers Before 1991 Are Difficult to Rank
The same problem exists with earlier men’s champions.
Modern stat tracking lets us know that Isner hit:
14,470.
But how many career aces did a legendary server from several decades earlier hit?
We may have:
individual match reports,
partial tournament statistics,
and historical accounts.
We do not necessarily have every match recorded under the same standardized system.
So a responsible historical article should distinguish:
measured records
from:
historical reputation.
Career Ace Records and the Tennis GOAT Debate
Career aces should have only limited weight in determining the greatest tennis player ever.
They measure:
one specific weapon.
Isner leads Federer.
That does not mean Isner had the greater career.
Karlovic leads Djokovic.
That does not mean Karlovic was the greater player.
The best GOAT analysis considers:
Grand Slam titles,
ranking dominance,
match wins,
longevity,
surface versatility,
head-to-head performance,
and many other factors.
Our complete approach is explained in How Is the Greatest Tennis Player of All Time Determined?.
What the Ace Leaderboard Really Measures
The most useful interpretation is:
career serving output.
It rewards:
big serving,
longevity,
many matches,
and the ability to repeatedly prevent opponents from touching the first shot of the point.
That is valuable information.
It simply needs to remain in its proper statistical role.

Final Answer: Who Has Hit the Most Aces in Tennis History?
The ATP career ace record belongs to:
John Isner — 14,470 aces.
The top 10 in the recorded ATP era currently stands at:
1. John Isner — 14,470
2. Ivo Karlovic — 13,728
3. Roger Federer — 11,478
4. Feliciano Lopez — 10,261
5. Goran Ivanisevic — 10,237
6. Andy Roddick — 9,074
7. Sam Querrey — 8,879
8. Pete Sampras — 8,858
9. Marin Cilic — 8,580
10. Milos Raonic — 8,445
Isner’s record reflects the perfect combination of:
height,
serve power,
placement,
longevity,
and enormous ace frequency.
Karlovic produced a similarly extreme serving career.
Federer reached third through a different formula based heavily on precision and disguise.
Ivanisevic and Lopez added the natural advantages of left-handed serving.
Roddick produced raw explosiveness.
Sampras demonstrated why the effectiveness of a serve cannot be measured only by ace totals.
And Cilic remains the one player in this top 10 whose number can still grow in 2026.
There is also one major historical qualification:
ATP ace statistics date from 1991.
So these are the official recorded-era records, not a perfect count of every ace struck throughout tennis history.
Within that recorded era, however, the answer is clear.
Nobody hit more career aces than:
John Isner.
Who Had the Greatest Serve Ever?
Isner produced the most career aces.
Karlovic created perhaps the most intimidating service angle.
Groth owns the speed record.
Roddick brought extraordinary explosiveness.
Ivanisevic used a devastating left-handed delivery.
Sampras produced huge serves when pressure was highest.
Federer combined accuracy with disguise.
So which one would you choose if you needed to hold serve to save a championship?
