Sam Groth - World's FASTEST Tennis Serve Ever! - 263.4 km/h !!!! (163.7 mph)

Busan, South Korea: Samuel Groth of Australia achieved a World Record of the fastest serve ever in tennis history with a service speed of 163.7 mph (263.4 kph) at the Busan Open 2012 Challenger Event. Although it is not yet officially recognized by the ATP due to variance in radar guns at challenger events, people still recognize him for such accomplishment.

I think we're ignoring how revolutionary of a video this is. It's an example of audio finally being able to be recorded with nothing but a raw potato found deep in an elephants asshole

[damienjuka]

glad the announcer was talking into a potato

I like how the commentator and crowd barely take notice. Casually goes unrecognised as the fastest tennis serve in history.

Is the Commentator a Russion CS:GO Player?

I guess when you're down triple match point, you might as well lay out all your frustration into one serve.

Now this is the pinnacle of video and audio quality, take notes YouTubers

It was so fast it made fast serves look...NOT FAST

[yoshikay]

Thank god he didn't serve it to the body!!

I love watching the fastest serve in slow motion

I love how the line umpire in the middle of the court started running when she heard the sound of Sam Groth´s bullet, although the serve was directed to the other side, in order to save her life:)

That ball should come with a health warning

[jamesglimco]

His serve was so fast the ball sounded like a gunshot

[ickenicke]

Even if you were there at the court, you couldn't actually say you "saw" that most brutal serve so far.

[Tutankamion]

Imagine hitting someone with a tennis ball at that speed? Insta death!

Commentator has a mic like my team in fortnite.

[CathyKitson]

Unbelievable. And I've never heard of this player!

[ThompterSHunson]

Breaking the world record and be like:

[blose]

[KoRnBaL]

I wish Sam woulda had a longer career in tennis. He was a beast. I guess his soul belonged to rugby.

When did he do this? 1904? Looks like it from the technology used to record this event.
