Pitch F/X: The Movers, the Shakers, the 14-inch Breakers
*** This was posted earlier, but I'm dumb and didn't realize it was a day game today. So...yeah, enjoy!***
Hello Rowbots! How about that game last night? Pretty solid I'd dare say. Ubaldo appears to have shaken off his spring jitters and come out ready to fight.
You'd think I'd be sick of writing about this guy, but he's really one of the most intriguing young players to grace the Colorado Rockies organization.
Strong points from last night:
Ubaldo Jimenez: 7.0 IP, 4H, 0R, 8K, 3BB, 7GB:6FB
The other strong points is that while the hit from Mark Reynolds COUNTS AS A HIT, it was a grounder deep in the hole to Tulo, and I don't think many shortstops not named Vizquel or Ozzie can make that play - and even with them I don't know. This is where BABIP and FIP come into play a bit more.
My point was more it was 2 line drive singles (one to LF, one to CF), a flyball double to RF, and then a groundball out that just didn't convert, you know?
Weak points:
Definitely worked a few counts, and obviously lost 3 guys. Left a few pitches up, but it's still early in the season.
I was really impressed with his outing. Ubaldo is really showing himself to be the guy.
But you already knew all that.
What I brought you in here to look at is Pitch F/X data.
BOOOORING I know, but this is where I feel we can all meet up and just have a good time looking at what Ubaldo can do. This is where the rubber meets the road: This is where the pitches actually land.
Join me after the jump for some analysis of Ubaldo's pitches, graphs, and there might be cake and punch.
Pitch F/X data comes from MLB, and is made available for analysis from such fine analysts as Josh Kalk from The Hardball Times. Josh has compiled a script that will take the online data made available to us and plot it in terms of either location or break, depending on which you want to see. Check it out at http://baseball.bornbybits.com/php/2008_tool - this link only has the 2008 data, but we're what, 2 games into 2009? He'll have more.
FOR EXAMPLE
Let's take a quick look at Ubaldo's curve. What I'm looking at specifically is the break. (You could look at Ubaldo's location, but I wouldn't recommend it. It's really all over the place.)
This is a collection of Jimenez's curveballs.
You can see the mass of the data really hovers around about 2 inches downward break and about 4 inches horizontal, but we also see a good chunk of the data closer to the 5 inch downward break and 7-10 inches horizontal. That's a pretty decent curve right there. Jimenez also got about 76mph on his curve last season, right where you'd expect it to complement a 95+ fastball.
Now let's take a look at that fastball. We know Jimenez gets good movement on his fastballs, which is absolutely critical. Much as I want Juan "Live Arm" Morillo to make it as a successful member of our team, we all know that that 98+mph heat is in the form of a straight, flat ball. In the show, everyone can hit heat. And yes, they've seen his heat.
So what does Jimenez do to set himself apart?
He gets movement.
Take a look at that. He typically gets about 5-7 inches break on his fastball (Negative break means pitch is breaking in to a right handed batter), and what appears to be a bit of rise. But there's also a nice little peninsula off to the left of the bulk that shows about 12-16 inches movement. That's not really an easy pitch to hit, especially when located.
Eric Byrnes was quoted during the game last night as having said that Jimenez once threw him a 97 mph fastball that ran 2 feet. Well, let's take a look at what Ubaldo did to Byrnes in 2008.
He averaged 99.24 mph on those fastballs. Dis-Gusting. And that movement? Maybe Byrnes was telling the truth, eh?
So yeah, movement's a big deal, am I right?
I'm going to go ahead and cut this short here for the week, but Pitch F/X basically is the tool we can now use to put money where the mouths are.
And when Ubaldo is pitching, that money is about 15 inches inside of where the mouth thought it was.

15 inch movement on a fastball? That is ludicrous!
Everyone says it is impossible for a pitch to rise…does this mean that “conventional wisdom” is wrong or that the accuracy of the pitch f/x models are an inexact science? And how does a curveball break UP?

That was my understanding as well
and I still haven’t entirely wrapped my head about it, but upward break is a common thing
read this for more insight http://statspeak.net/2008/06/breaking-down-the-heater.html
I am as well ;)

Thanks
I might be able to buy upward break on a fastball, but a curve?

It may be basing on the delta between where it crosses the plane and the release point

The movement on the pitches
is relative to the plane created by a theoretical pitch thrown with no spin. The fastball was 15 inches higher than a pitch with no spin. or something like that
Anyway, RMN I don’t care how many people think this stuff is boring, you keep posting it! Pitch f/x is the future…
Do you know...?
I assume that is adjusted based on the release point each time, so that it’s an even comparison between pitchers of different heights and arm angles….and when a pitcher drops down for a pitch?

yea, I was thinking that too
randy johnson and tim lincecum will have different planes. I’m not sure if it’s calibrated to that degree or not. I just know that the spinless pitch comparison is why the fastball can have 10 inches of “upward” movement. I suppose if it’s not calibrated, it’s one of those “well its still better than anything else we have currently” arguments…
Sure
I’d like to see a player pitch f/x minus league average. Since both the player in question and league average would involve the spinless pitch, the difference would eliminate its effect

Well another thing is that they aren't accounting for is varying strike zones
Richie Sexson and David Eckstein have very different zones. A strike on Sexson is a ball for Eckstein.

well that's for sure
I had thought it might be taken into account already. hmm

Not only that, but
different umpires have different zones. And their zones can vary from game to game and even pitch to pitch. I guess the pitch f/x should be able to tell where a pitch is relative to the plate (inside or outside), but the vertical location relative to the strike zone would depend on both the hitter and the umpire.
I'm going to comment on Ubaldo
since none of the comments thus far has touched on the actual subject of this piece.
15" horizontal movement on a fastball?! That is insane. That not only moves off the sweet spot, it moves to the handle. This article increases my admiration for Ubaldo twofold, and that is hard to do

In an effort to remain on topic
It doesn’t look like his curve breaks too much compared to other pitch f/x curveball data I’ve seen, however, Ubaldo tends to throw harder than most so his curve may have less time to break, also, if his curve release point is similar to his fastball/changeup release point and it’s trajectory mimics the fastball’s (IE a small hump in the arc of the curve), Ubaldo can get away with a curve that doesn’t break as much. That being said, a sizeable portion of his curveballs did have significant downward and horizonal movement…
It is definitely more of a power curve than a big rainbowing yakker
and it seems to me that with his control issues and the whole “wildly effective” aspect of his game, it doesn’t HAVE to be a monster, it just needs to come back in/out a bit so they’ll be anticipating just another ball.

I thought he did a good job of controlling his pitches
up until it was time to put the batter away, then he’d start nibbling.
I thought power curves were more in low to mid 80’s velocity-wise, not mid 70’s like Ubaldo – I could just be thinking of K-rod whose power curve is more the exception than the rule…
And I'm just trying to put a name to it, I could be wrong too
but it never seems to be a biiiiiiiiIIIIIIIIiiiiiiigggg curve, but rather a tight late breaker
