fastest pitch recorded

[glennnphp]

i've asked a few people and have never got a definitive answer - i think i remember Tekulve breaking 100+ once or twice, but i'm not sure... aren't there a few pitches recorded at about 103 MPH in the past...?

i know you guys know this. i don't.

there are many answers to this question, depending on whose clock you believe. the radar guns at ballparks are hardly well calibrated, so they can't really be relied on.

The Guiness Book of World Records recognizes Nolan Ryan at 100.9, based on a game they recorded in 1974.

You'll see many stadiums show 100, 101 and even 102 or 103 from time to time, but that is hardly conclusive. Steve Dalkowski should always be in this conversation, although no one can say with certainty how fast he actually threw

If you do a search on this site, I believe you'll find other threads regarding this

i printed a list a week ago and mark wohlers and joel zumiya threw won 103 mph.

Which gun did they use for Zumaya. Hope it wasn't the FOX TRACKER that is 3mph or so faster then the JUGS and the JUGS is 3mph or so faster then the speed gun the scouts use. The FOX TRACKER picks up ball right out of the pitchers hand compared to 6 inches out of the hand like the JUGS which I believe is the mosted used by the ballparks. Those 3 pitches that Zumaya struck out A Rod on in the 2006 playoffs were like 103/102/100 by the FOX TRACKER but none of them crossed the plate over 95 or 96.

Most recognition still go's to Nolan Ryans 100.9 that Brooklyn posted.

Although not official, the fastest observed fastball speed was a pitch from Mark Wohlers during spring training in 1995, which allegedly clocked in at 103 mph.[6]

The official record according to the Guinness Book of World Records is 100.9 mph by Nolan Ryan in 1974. Ryan's pitch was clocked using coherent infrared radar.[7]

The reliability of radar guns used at MLB games more recently has been questioned. USA Today columnist Mike Lopresti reported that FOX was using radar guns which recorded speeds 3 to 4 miles an hour faster than the readings on the McAfee Coliseum radar guns in Game 1 of the 2006 American League Championship Series.

article and comments on the night they recorded ryan's pitches...interesting read.

I am pretty sure Joel Zumaya did throw 103 mph because I went to a game where he threw and it clocked at 103 on the stadiums radar and 100-102 numerous times. I also watched Fox's tracker and it also read 100-102 in many other games. I think Nolan Ryan is the most reconizeable fastest thrower but I do think The Guiness Book of World Records has to renew the record as everyone knows it could and would be broken. I do reconize Nolan Ryan as one of the top pitchers ever to play the game.

No way Tekulve threw anywhere near 100. You must be confusing him with some other pitcher.

One issue with measuring a fastball is the fact that as soon as the ball leaves the pitcher's hand air resistance begins slowing it down. A fastball loses about 8 MPH between the pitcher's hand and home plate. I read an article about the measurement of Nolan Ryan which indicated that the measuring device used a doppler-effect infrared laser which was located up in the stands behind home plate, aimed over the catcher's head at a point maybe 10 or 15 feet in front of home plate. In the 35 or 40 feet after leaving Ryan's hand the ball probably slowed by 5 or 6 MPH. So the "muzzle velocity" for a pitch measured at 100.9 MPH would have had to be about 106 or 107 MPH. I don't know how quickly a modern speed gun registers, but I doubt it catches the precise release point. It makes a difference if the gun is reading the ball 10 ft. out of the pitcher's hand or 30, in the extra 20 ft. The ball would lose perhaps 3 MPH.

So, without the exact details of the measurement even a perfectly working gun does not tell you exactly how fast a pitch was. The best you can say is the ball was at that speed at some point.

Steve Dalkowski threw at 108.something mph in a minor league game one time.

"Steve Dalkowski threw at 108.something mph in a minor league game one time."

He was? Seriously, while I believe Steve Dalkowski could probably hit 103 mph and probably threw slightly harder than Joel Zumaya, that's about the limit of the human arm without the tendons in your ulnar collateral ligament flying apart. Steve's arm structure was rather unique...his left arm was a lot like Satchel Paige's right arm. He threw with a max effort delivery, used an incredibly fast arm action, and take a look at a picture of Steve's stride and it's quite similar to that of Tim Lincecum in length. While Steve probably was among the fastest pitchers of all time, he probably seemed to throw even harder, as well. Could he hit 108? Depends on your definition of throwing 108 mph (see below). Could he do it all the time? Same answer as before. Was he ever timed at 108? No. Where did this myth come from? Read on.

When Dalkowski threw a fastball that was actually clocked, it registered at (according to conflicting reports) 99.8 mph or 93.8 mph. Considering Steve's sister claims the latter speed is correct, we'll go with that. However, keep in mind the following: Dalkowski, like Nolan Ryan, was timed at 60'6". Today's pitchers are timed at 45 feet from the mound. Dalkowski also lost a few mph throwing off flat ground and throwing over fifty pitches before he finally registered one single speed. It's likely Dalkowski could hit 100-103 mph at 60'6", which is 1-3 mph more than what Ryan threw. Now consider that a pitcher loses anywhere from 5-7 mph from 45 feet to 60 feet 6 inches (let's assume 5 mph, since that's the minimum). Add in 1-2 mph from that loss of throwing off flat ground, and all of a sudden Dalkowski is throwing 99-100 mph with that pitch on a modern gun taking readings at 45 feet. Further, all of a sudden, Ryan is throwing 105 at least and 107 at most (since speed guns have registered that much on one of Joel Zumaya's best pitches at 45 feet, it's no longer impossible).

But let's go back to answering our original question...how did this myth come about? Well, add 7 (max limit of pitch velocity loss from 45 feet to 60'6") and 1 mph (from having lost that throwing off the mound) to 99.8 (the incorrect measurement) and round up. What do you get? That's right...108 mph. Seems someone was guessing what that pitch would do on a modern radar gun and did it with the wrong info.

This is all about perspective. Could Steve Dalkowski throw 108 at 60'6" (which is basically what matters)? No, that's not humanly possible. Consider that ASMI is referring to 60'6" when asked what the limit of the human arm is (about 105 mph). But could he throw that at 45 feet? I have no doubt. Considering he actually caught Steve Dalkowski AND Nolan Ryan, I'll go with Andy Etchebarren as saying that Dalkowski was definitely faster than Ryan, but not to the point where they were incomparable. Then we have the inevitable question that follows...could Nolan Ryan throw that hard at 45 feet? Almost certainly. When we see Ryan finally recorded on a modern JUGS Radar gun at 45 feet, he's played over 15 years of his career. Both Dalkowski and Ryan in their primes likely threw as hard or a little harder than Joel Zumaya...whose fastest pitches likely top off around 99-100 mph at 60'6".

Nolan Ryan is the fastest - 108.1 mph

Nolan Ryan is the fastest. See http://www.efastball.com/baseball/st...major-leagues/

1. Ryan - approx. 108.1 mph at 50ft
He measured 100.9 mph at 10 feet from the plate. Add 7.2 mph for the loss of 40 feet (avg 9mph loss from 50ft to plate). Approx 99 mph plate speed.

2. Joel Zumaya - 104.8 at 50 feet
93.7 plate speed

3. Mark Wohlers - 103 at 50 feet
No confirmation on this measurement. Which game? Date? Radar? etc.

[Dalkowski110]

That figure is a little hot. Like I said, a pitcher loses 5-7 mph on the way to home plate, not around 9-10 mph. Although, it's interesting to see Zumaya's plate speed. Bob Feller was also faster than Zumaya (Feller threw 99.7 mph at the plate) and Steve Dalkowski hit 93.8 (thus being 0.1 mph faster than Zumaya with no mound, having thrown continuously for fifteen minutes, and started a game the day before).

Speed drop to plate

The average speed drop to the plate for a 100mph pitch is 9 mph ranging from 7 to 11 mph.
