  1. Almost looks as though there’s some change in velocity while on route. Is that physically possible?

  2. Well, it can slow down.

  3. I would vote for a combination of hiding the ball well and strong arm-side run like Frieri minus 5 mph.

  4. Velocity is a vector value. A change in direction is also a change in velocity.

  5. Combine this with Earl Grayson’s stopball from Maniac Magee, and baby, you got a stew going!

  6. His fastball seems to have a bit of late giddyup on it ala Matt Cain.

  7. Its possible some players throw balls with massive differences in spin rpm, which could result in different decelerations from different pitchers.

    Hmmmm….now I look at brooks baseball, and Redmond’s fastball max speed was 91.1mph and the avg speed is 89.33, a difference of 1.77mph.

    Just a quick look through the other pitchers in that game and the avg speeds and max speeds are generally within 0.5mph.

    Redmond somehow makes his ball slow down faster??????

    Does not compute. Maybe he excretes gas that increases the air friction.

  8. My totally unfounded theory based on that isolated .gif and the numerology above is that something about his delivery/arm movement/release gives it a deceptive cut motion/look initially perceived by hitters while the spin of the ball straightens it back out and makes it hard to square up. You know, like a knucklefastball.

  9. More seriously now, Redmond’s delivery in that GIF looks similar to Anthony Slama, and Slama’s got the same story… underwhelming fastball, but he seems to have enough deception in his delivery that minor league hitters can’t hit it.

  10. Should have included this in the original comment, but it would be interesting to find other pitchers with arm actions similar to Redmond/Slama and compare them with their fastball velocities and run values to see if they have similar success. However, we’d need pitchers with more major league innings, as Redmond and Slama clearly don’t have enough to be meaningful.

  11. actually if someone can post a .gif of pedro he threw at a very similar arm angle.. kinda similar action too now I look at it

  12. Yeah, maybe people are actually thinking knuckleball, for just an instant.

  13. Most pitchers try to throw their changeup to look like a fastball. Redmond’s fastball looks like a changeup.

  14. This. He looks like he’s about to throw a 77 mph curve or something and out comes a fastball.

  15. This. He looks like he’s about to throw a 77 mph curve or something and out comes a fastball. He also seems to have a hitch in his delivery/timing before he rotates his shoulders, which could cause problems with batters’ timing on the fastball.

    My explanation: small sample size, but also mlb batters aren’t familiar with his delivery.

  16. J A Happ was doing a similar thing in his last start for Toronto. That is, pitching high in the zone and somehow getting Ks with a 90mph fastball that should have otherwise been crushed. At one point, Happ got 6 Ks in a row.

  17. Hamilton was behind on that pitch. Sneaky fast 91 mph?

    Comment by payroll — August 21, 2012 @ 9:58 am

  18. Short arming it and hiding the ball behind his head during his delivery?

    Comment by Walter — August 21, 2012 @ 10:32 am

  19. What was his veloicity on his other pitches? If he repeats his delivery real well, the hitter might be expecting low 80′s and can’t adjust in time to catch up to the 88-90 mph fastball.

    Keith Foulke seemed to do this a lot in his prime, getting swinging Ks on letter high 86mph fastballs after a string of 77-82mph sinkers and sliders

  20. Hoodoo, plain and simple.

    Comment by Bigmouth — August 21, 2012 @ 11:48 am

  21. I agree, I read curveball with how his motion is on that pitch. I think it’s his follow through/ throwing across his body? Seems like he plants his left foot at a wierd time then just kind of hangs onto the ball while still finishing his delivery

  22. Is there any way to judge “perceived velocity”? I was watching the LLWS and they do the “if this were from 60’6″, it’d be this fast” thing and I was wondering about pitchers. It’s a reaction time thing. The actual amount of time a batter has to recognize the pitch is really the “velocity”. Obviously, if you throw hard anyways it helps. Deception is another thing I think it’d be cool to be able to measure.

  23. Wow we need to see that in slow motion
