The greatest reliably recorded speed at which a baseball has been pitched is 100.9 mph by Lynn Nolan Ryan (California Angels) at Anaheim Stadium in California on August 20, 1974. >>http://en.wikipedia.org/wiki/Lynn_Nolan_Ryan_Jr

Joel Zumaya of the Detroit Tigers has been clocked at 103 mph

I AM A SPORTS WRITER FROM ESPN AND I AM HERE TO TELL YOU THAT THE FASTEST PITCH EVER THROWN IN THE HISTORY OF MLB BASEBALL WAS BY "BILLY WAGNER" IN 2004 HE WAS CLOCKED AT 107 MPH.

Ross Martin a 6 foot 9 270 pound beast. Absolutley ripped, recently burned a fastball at 104 mph in a game the other night in a high school Div 1 baseball game.

Ryan Cooley and Justin Fielder were clocked in left field bleachers at Comerica Park @ 63.7 mph. FAAAST

the fastest pitch i have ever seen was in 2002 astos vs. yankees roger clemens throught a fast ball clocked at 117 mph

tyler hibbs threw a ball 145 MPH that went through a wall

i watched a twins pitcher threw a 102 miles per hour baseball in 2006

ok ur all reatarded espically the one that said u cant throw a baseball faster than 100.9 Mariano Rivera when he was freh,young, strong could throw 103 tops maybe 104

i threw 89 at 11 years old...so i Imagen that some one could throw 110..but with no control

The fastest pitch I've seen from a MLB pitcher is 103mph from Joel Zumaya from the Detroit Tigers in 2006, although the statistic may be a little inflated, I would not be at any length surprised if he did surpass the 100.9 record set by Nolan Ryan, but currently Nolan Ryan's record stands only because his was the only one actually monitored by World-Record officials. As far as the credibility of the answers stating that someone threw 110mph plus, those I wouldn't believe. The MLB is by most peoples standards the top notch level of pitching (as well as playing standard) in the world. Not to say that America has the best players, but that all of the best players are usually sent to the MLB. That being said, the fact that (a rough estimate) of 95% of pitchers struggle to reach 100mph even on a rare basis, the ones who are gifted enough to reach over 100mph, wouldn't be able to go much above that. I doubt anyone has seen someone throw a baseball 145mph through a wall, or even 113.6mph, but although nobody can really be certain of the fastest pitch ever thrown in an MLB game because of how often the radar guns are purposely or accidentally miscalculated, the current "Official" record stands at 100.9 from Nolan Ryan.

I work as a baseball trainer, mainly with young pitchers. Any claim that anyone has thrown anything over 105 mph is BS. Joel Zumaya is a perfect example of such a stature. He spent 4 years in the minors throwing an average of 94, able to crank it to 97 here and there but as he worked at it he obviously reached 103 during some games last year (one I saw in person). He took some months off this year due to a hand injury and is just now working up to 97 again, doubtful he'll be hitting 103 mph again if ever. Its an underestimated mark and for the guy who said he hit 89 when he was 11 is the dumbest thing I've ever heard, you wouldn't be writing on yahoo comments if that were true you'd be making millions and worshipped, I work with plenty of 11 year olds that average around 60 mph. By the way, in the movie "Ed" Matt Leblanc hit 125 mph as a minor league pitcher, always found that to be hilarious.

when the guy said that when he was 11 he threw 89, why didnt you believe him.... dont think that is possible?.... well it is and you are wrong a person could throw that... i have seen it myself. As for throwing the ball over 100 mph... i have seen it done many times. Once i was with my buddy and dad and we had seats at a twins game behind the plate. he decided to bring his juggs radar gun just to see if that was right... and we clocked a guy at 103mph... and he calibrates his gun all of the time!

nolan ryans 101.9 mph fastball was the fastest pitch ever....scientifically proven not off a radar gun. no one in hell can throw a 113 mph

I know that Randy Johnson threw one at 110 mph and exploded a bird on that pitch.

Hello I am Alex Trunk and i play at Salisbury High School in Allentown Pennsylvania. I was recently clocked throwing at 120 mph. This is no BS. This is real give me a call.

ok.first of all the reason why its impossible IMPOSSIBLE to hit over 105..ever.. is the arm action a MLB or any men's baseball pitcher uses..the obvious way is stanard over hand,but theres sidearm,submarine,three-quarters..ok anyway..the rotation in your shoulder,elbow,wrist, and even fingers restricts your body from being able to throw that hard..no matter how hard you work out your shoulder or how much HGH(pettite,Clemens) you could use..the fact of the matter is your shoulder is esentially out of its natural element when throwing a pitch..it simply doesn't give you the ability to throw that hard..the guys who have hit 100+ in mlb,aaa,aa,a,h.s,A.A.U.,little leauge,t-ball..simply throw the same way..just have an incredible amount of strength to muscle it up 100+...but your strength cannot stop the natural way your built, mark wholers has thrown 105 on game radars, which r flawed. only he hit the backstop well over the umpires head..ur body just doesn't allow you to do it, and if u could...you couldnt hit a barn door..

ive been a big baseball fan for 35 years,an the fastest pitch ive ever seen was by joel zumaya at 103. ive seen joba chamberlin hit 102 on the gun. i dont think a human can throw much harder than that.i have heard stories about players who have thrown 105,110,113,120,an 135 but its just so hard to believe that the human body could take that much punishment without blowin out your arm,an shoulder.

If they had enough technology to officially read the velocity of a thrown baseball in 1974, why can't we officially read and record the velocity of a thrown baseball 34 years later. Given today's record-mad society, why wouldn't the Guiness World's Record Book people have recorded Randy Johnson a decade ago, or why wouldn't they be ready to track the pitches of a now-healthy Zumaya? I'm from Detroit and have watched Zoom throw consistent 101-103 mph fastballs in short relief... if it would qualify as an MLB record but the guns at the park are deemed unofficial, why on earth wouldn't they make an attempt to document this legitimately, since their gold standard dates back to 1974? ESPECIALLY considering the illegitimacy they willingly allowed another 1974 gold standard to fall by the wayside. Funny how Barry Bonds' juice-filled final years of his career are fine for the record books, but they put their foot down hard on Zoom's numerous 103mph pitches (clocked by multiple speed guns) due to the inaccuracy of this type of gun. And people think the sport is screwed up.

ive seen the now giants closer brian wilson throw in the 100's many times last night he hit it 7 times and that a typical game for him also he throws a slider between 90 and 95 unfortunatly he has little control of his fast ball or slider if he can find some he will dominate. also i sawl for many years robb nenn throw consistenly in the 100's

I am 17 years old and have been officially clocked at 97 on the jugs gun. I've been recruited by several American League teams including the Red Sox. They told me that I have a chance at their minor league system if I work on my control. The great think about me is that I am still growing he says I might be able to throw 105 when I fully fill out. I'm almost 6 feet now. In 45 innings at Crown Glory Academy I have struck out 35 batters and walked 10 (I need to work on that). These stats are very impressive. If I don't attend a tryout with the Red Sox I may enroll in college because I know how important education is just in case things don't work out at the tryout.

It all depends on the arm slot. The fastest pitchers are sidearmers, and they consistently throw over 100mph. However, because the gun doesnt pick up the ball until it's halfway to the plate, they often are clocked in the 80s. Dan Quisenberry was the hardest thrower of all time, but nobody nows this

When a pitch is clocked it is never accurate so the only way that you could tell witch pitch is the fastest you would have to have a mass measureing system and pitch at that and calculate the mass into speed

Hi I am From Venezuela I was Wondering The Record Speed... I Found Something Seems A Little Accurate at least have some sense to me http://hypertextbook.com/facts/2000/LoriGrabel.shtml I Think The Record Is 103 MPH.... Anything Else Is Hard To Believe..... Thanks By Read This Christian Ortiz C --->ChiperOrtiz@Hotmail.com Venezuela....

This year Joba Chamberlain threw one that went 104.

several people have throwm 104. Randy Johnson Joba Chamberlan Joel Zumia (spelling)

The fastest pitch ever recorded in Major League Baseball history, both on and off the official field is 104 MPH, by Bob Feller in Lincoln Park, Chicago, during a bullpen session on a day off.

Eric Gagne & Guillermo Mota for the brewers can both pitch 101 mph, seth mcclung, ben sheets, cc sabathia, and derik turnbow all also for the brewers can pitch 100 mph.

eFastball.com already solved this. The problem is where measurement was taken (hand or plate). 1. Nolan Ryan 108.1 (100.9 10ft) 2. Bob Feller 107.6 (98.5 plate) 3. Joel Zumaya 104.8 (93.7 plate)

nolan ryan 101 is wrong it is randy johnson at 106.5 mph

nolan ryan at 101 mph is wrong i know for a fact that it wasrnady johnson in 1997 who threw 106.5 i was there

ur all wrowng i don't care wat any one says it is 115 mph.

The record still stands with The Von Ryan Express at 100.9, but I could've sworn that pitchers like Joel Zamaya,Billy Wagner and Ubaldo Jimenez have thrown 101 plus. Of course, it's rumored that stadiums hike up publicly displayed radar guns for fan amusement.

Recently i have heard that Fernando Rodney of the detroit Tigers threw a pitch was 104 MPH in a game last year or 2 years ago

ive heard that satchel paige threw the fastest pitch ever in baseball by just looking at how fast he pitched but back then there were no such things as radar guns and he was in the negroe leagus which at the time didnt matter the only reason they had negroe leagus was because of the war and it amused people . and to add satchel paige was supposedly by some researchers the fastest pirtcher ever

the fastest pitch that has been verified twice by two radar guns was 100.6 mph by Nolan Ryan in 1973

In 1980, Nolan Ryan came to the Astros and was teammed with a man that, until Joel Zumaya, was the only pitcher to throw harder than Ryan himself. That man was J.R.Richard. In 1979, Richard, who had been known to hit 102 on the radar gun in the past, topped his own mark when he recorded a speed of 104 m.p.h.

The highest recorded pitch IN A GAME is by Nolan Ryan, however Justin Verlander has been recorded as pitching at over 102 in bullpen. Being that it was not in a gameit is not recorded by Guiness.

Some claim Walter Johnson threw 105, cause when he threw it, it whistled

its no more then 102. and that was nolan ryan in the 1970 s. u guys are all wrong. when the juggs batt. weakens the timings become inaccurate. wohlers hit 101 pretty consistantly. i have a juggs gun and i would time him in philly.

Fastball Nolyan Ryan or Satch

Jaret Wright clocked a wild pitch while playing for the San Diego Padres at 112 mph. The fastest recorded hockey puck was hit by Zdeno Chara of the Boston Bruins at 109 mph. Just a little comparison.

Nolan Ryan threw one that was like 102 mph.

Walter Johnson and Bob Feller threw faster than any of these clowns today

Lol, around 113. I'm 14 and throw 78 though :p Ima throw 114 tomorrow, just to throw off the balance.

i threw the bag o' weed out my window while getting pulled over.. the cop's radar thought it was a bullet cause it clocked in his radar over 200 mph....

Joel Zumaya has the fastest that was ever recorded but we can't say for sure because guys like Bob Feller and Walter Johnson were never truly measured.

the fastest pitch ever recorded during game was joel zumaya in 2006 at 103 mph or 104 mph - depending on source? im from detroit and they told us he hit 104 that night, so who know knows, ryan never hit over 101, but radar guns might not have been as good then?

i just saw Zumaya pitch 105 no lies

I was watching a game a long time ago and on the speed gun on the TV, Rob Dibble a reliefe pitcher throw 101, not sure how accurate that was

Nolan Ryan....FACT...NOT FANFARE....get over it

At the Minnesota Twins Metrodome on july 3rd 2009, the Detroit Tigers Joel Zumaya threw a pitch that was registered at 105. It was in the bottom of the 10th inning i believe (although it may have been the bottom of the 11th, the innings tend to blend into each other in a 16 inning game). It has yet to be "officially" verified (and thus placed among the record books). He registered 1 other pitch at 104 and several more at 103. I personally watched the game and as a Tigers fan, have seen him pitch in about 85% of his games. On a side note, I was at the TIgers-Astros game on 06-27-06 when Zumaya threw 103 in the top of the 8th 3 times. Interestingly, Roger "The Rocket" Clemens started for Astros, and hit 97 mph once, but that pitch looked like a change up in comparison to Zumaya's fastballs. Seeing a fast pitch on TV does NO justice to witnessing that speed in person. It should be noted though that the Metrodome is one of the the most notorious fields for the ball moving significantly quicker than other fields (and no, the "air conditioner" theory about blowing the ball is a fallacy, the difference in barometric pressure inside the aging dome as opposed to the outdoors or other modern domes is the most likely explanation for this widely known unusual behavior of the ball) This also may be part of the reason why the Twins play so well at home especially in recent history. Also, The biomechanical limits of the human body based on fixed ratios of arm bone lengths, tendon & ligament maximum strength and the size of the muscles required to throw XXX speed set a scientific and mathematically calculated limit on the speed a ball can be thrown at 105 mph. Any pitch reported to be faster was either thrown by Robocop or was recorded by an inaccurate or outdated radar gun. For instance, Bob Fellers "107 mph pitch" allegedly recorded at an airforce base was corrected and recalculated to be 98 mph, due to the primitive nature of the radar gun (which was just being developed at that time). accurate speed readings on radar guns (for the sake of "records") weren't developed enough to be reliable until the early 1990's, so any pitch speeds recorded before then should not be trusted as accurate. --> All information (to the very best of my knowledge) is accurate, true and verifiable if you wish to research it. -If Joel Zumaya could keep his shoulder in one piece, he would be much more formidable. Strangely enough, his offspeed power curveball (thrown between 83-87 mph) seems to be his most effective pitch because of the change of speed and movement that juxtaposes his laser beam 4SFB, but he unfortunately relies almost entirely on his 4SFB, which he typically throws about 90% of the time.

In its April 1985 edition, Sports Illustrated published an article by George Plimpton that described an incredible rookie baseball player who was training at the Mets camp in St. Petersburg, Florida. The player was named Sidd Finch (Sidd being short for Siddhartha, the Indian mystic in Hermann Hesse’s book of the same name). He could reportedly pitch a baseball at 168 mph with pinpoint accuracy.
