Well, let me tell you, I heard some folks talkin’ ’bout tennis the other day. They were goin’ on and on about how fast them players can hit that little ball. Got me thinkin’, what’s the fastest serve in tennis? Ain’t never seen nothin’ like it, I tell ya.
These young folks with their fancy rackets, they sure can whack that ball. I heard one fella, name of Sam Groth, hit that ball so hard, it went faster than a horse runnin’ from a wildfire. They said it went 163 miles in an hour. Now, I don’t know ’bout all them numbers, but that sounds mighty fast to me. Faster than anything I ever did see.

Fastest Serve: Men
This Groth fella, he did it at some fancy Challenger thing. Not sure what that is, but it sounds important. Then there’s another one, John Isner. That’s a name I can remember. He hit one 157 miles an hour, they say. That was at some Davis Cup. Sounds like a big deal, that Davis Cup. Imagine hittin’ a ball that fast. My old arm would probably fall right off!
And Milos Raonic, hit one 155 miles in an hour. That SAP Open, they call it, like openin’ a can of beans, but a whole lot faster, I reckon.
- Sam Groth – 163.7 mph (263.4 km/h) at a Challenger event.
- John Isner – 157.2 mph (253 km/h) at the Davis Cup.
- Milos Raonic – 155.3 mph (250.0 km/h) at the SAP Open.
There is also another man, called Oscar Otte. This German tennis player, hit the ball very fast during his match at the 2021 US Open. They say it is the fastest in the history. That must be very fast!
They got some group, called ATP, that keeps track of all this. Association of Tennis Professionals, they call it. Sounds real official, don’t it? They make sure everyone’s playin’ fair and square, I suppose. And they keep track of who hits the ball the fastest.
Fastest Serve: Women
Now, the ladies, they ain’t no slouches either. There’s this one gal, Sabine Lisicki. She’s from Germany, I hear. She hit that ball 131 miles an hour. That’s faster than a chicken runnin’ from the fox! She did that at the Stanford Classic. Sounds like a real fancy place.

And another one, Aryna Sabalenka, she’s no slowpoke either. Hit that ball 133 miles an hour, they say. That was at the WTA Elite Trophy. Another one of them fancy tournaments, I reckon. The women, they don’t keep track of their speeds like the men do. Don’t know why. Maybe they just don’t care as much ’bout them numbers.
- Sabine Lisicki – 131 mph (210.8 km/h) at the Stanford Classic.
- Aryna Sabalenka – 133 mph (214 km/h) at the WTA Elite Trophy.
But I tell you what, seein’ them folks hit that ball, it’s somethin’ else. Makes me tired just watchin’ ’em. All that runnin’ and jumpin’ and swingin’. They must be in some kinda shape, I tell ya. Us old folks, we just sit back and watch. Maybe have a glass of sweet tea while we’re at it.
But you know, even though I don’t play no tennis, I can appreciate a good, hard hit. It takes a lot of strength and practice, I imagine. And them players, they got it. They can hit that fastest serve like nobody’s business. It’s like lightnin’ strikin’, it’s so quick. They got all these tournaments, Wimbledon, US Open, all kinds of places where they hit that ball real fast.
It’s a whole different world, that tennis world. But it sure is interestin’ to watch. And them fastest serves, well, they’re just somethin’ else. I don’t know how they do it, but they do. And it’s a sight to behold, I tell ya. A real sight to behold.
I reckon, they practice and practice, hittin’ that ball over and over again. Gotta have a good arm for it, that’s for sure. And good eyes, too. Gotta keep your eye on that ball, or you’ll miss it for sure.

So, the next time you see them tennis players on that TV, you just remember how fast they can hit that ball. It’s faster than anything you ever did see. And it takes a lot of skill, that’s for sure. A whole lot of skill. These players work hard, day in and day out. They got to.
Anyways, that’s all I know about the fastest serve in tennis. It’s a lot of numbers and names, but the main thing is, them folks can hit that ball real fast. Real fast indeed. And that’s somethin’ to admire, ain’t it? Sure is. It’s a wonder to me, that’s what it is. A real wonder.
