Brad Ziegler Is a Freak
Relievers are the hot new thing, you might have heard. Aroldis Chapman and Kenley Jansen got north of $80 million, plus opt-outs. Mark Melancon got $62 million, plus an opt-out. Mike Dunn got $19 million. Mike Dunn! Perhaps nothing says reliever inflation more than Mike Dunn getting $19 million. Or maybe that just says he signed with the Rockies, and the Rockies are weird. But Colorado bizarreness aside, good relievers aren’t cheap anymore.
Well, unless they’re good in a really weird way, anyway.
Wherever he ends up, Brad Ziegler is expected to land ~2 years, $17 million. Not bad for a 37-year-old with an 84-mph fastball. cc @ithrow88

This is just how it is when you’re an oddball. I’m sure Brad Ziegler is used to it by now, but it is interesting that the hook here isn’t that Ziegler is a good reliever getting less than a mediocre LOOGY got a few days ago, but that Ziegler is a reliever without a traditional big league fastball. When, velocity aside, let’s be clear that Brad Ziegler’s track record makes it inarguable that he’s been a very good reliever.
Over the last three years, Ziegler is one of just 15 relievers to have thrown at least 200 innings. Of that group, his +5.1 RA9-WAR ranks 7th, right between Jeurys Familia and Cody Allen. If we lower the bar to 150 innings to let some guys in who have worked less — and thus, switch to a rate stat to compensate for the difference in workloads — we find Ziegler’s .273 wOBA allowed is basically the equal of David Robertson’s .270 mark. We can slice and dice things all kinds of ways, but the conclusion is basically always the same; Brad Ziegler has performed at the kind of level that should make him a household name.
But Ziegler is still kind of anonymous, because, as Passan notes, he throws 84 mph and he doesn’t strike anyone out. Of the 77 relievers who have thrown at least 150 innings over the last three years, Ziegler ranks 70th in strikeout rate and 77th in fastball velocity. And in the latter category, it’s not even really close. The next slowest throwing reliever is Darren O’Day, who is up near 87. Ziegler isn’t just the softest tosser; he’s the softest tosser by almost three miles per hour.
But that’s actually not what makes Ziegler so weird. The velocity is a fun trivia question, but here’s the really insane thing about how Ziegler gets people out; he succeeds in a way that basically no one else can replicate. If all you knew about a guy was that he threw 84 and he got people out anyway, you’d almost certainly assume he pounds the strike zone, right? This is the Bartolo Colon plan, or before him, Jamie Moyer. We’ve seen guys without good fastballs succeed, and it’s almost always because they can paint the corners of the strike zone with precision.
Brad Ziegler doesn’t do that. Brad Ziegler does the exact opposite of that. Below is a chart of all the qualified relievers in baseball over the last three years, with their walk rates and Zone% listed on the x/y axes.
This chart is mostly what you’d expect; the guys in the upper half of the graph are the strike-throwers, the guys who pound the zone, and by and large, they live on the left side side of the graph, where the low walk rates are represented. As you go down in Zone%, your walk rate goes up, so you move right on this chart. It’s not a perfectly linear arrangement, but the obvious is basically true; the guys who throw strikes don’t walk guys, and the guys who don’t throw strikes do.
Except Brad Ziegler, who is labeled on the chart, even though he probably doesn’t need to be, since his little dot would stand out regardless. Ziegler, you’ll note, is the lowest dot on the chart, meaning he has thrown a lower rate of pitches in the zone than any other qualified reliever in baseball. And yet, his walk rate during that time is basically league average. Every other pitcher with a Zone% under 40% has a double-digit walk rate, and is generally not a great pitcher. The guys at least remotely near him in strike throwing? Zach Putnam, Chasen Shreve, Marc Rzepczynski, Javier Lopez, and Gonzalez Germen. These guys aren’t great, because by and large, they walk too many guys to be effective.
Ziegler, though, lives out of the zone more than any other pitcher, and yet, walks aren’t really a problem for him. This is, in part, because he throws a pitch that hitters just never see otherwise, and don’t really know how to handle. August Fagerstrom wrote about Ziegler’s absurd swing-inducing-yet-never-in-the-zone change-up back in February.
Changeup – Brad Ziegler
- Thrown out of the zone: 85% of the time
- Swung at, when out of the zone: 54% of the time
- Meaning: 46% of the time this pitch is thrown, it’s both a) out of the zone and b) swung at
This was the hardest pitch in all of baseball to lay off last year, by my methodology. Which makes sense, given it could just be the rarest pitch in baseball. Yes, that’s right. Eno Sarris wrote about this very pitch at length for FOXSports last year, noting the oddity of a submarine pitcher throwing a changeup.
Sarris explains:
“You pronate (‘pull down’ on the inside the ball for a righty) with the changeup and supinate (pull down on the outside of the ball) with breaking pitches, generally.
…
There are only three true submariners pitching right now. But it also seems like the physics of throwing a changeup from down under make things difficult. Try to mimic pulling down on the inside of the ball from that angle, and you’ll see that it is difficult to pull off.”
The way a changeup’s spin is achieved and the way a submariner’s mechanics work are like oil and water, yet Ziegler has found a way to blend the two. Few batters have ever seen a pitch that moves like Ziegler’s from Ziegler’s arm slot, and so it makes sense that they have a hard time laying off.
When I first watched the video, the pitch didn’t actually look that low, but it was actually the lowest changeup Ziegler threw that got a swing all year. Must be the deception. And the fact that he puts it right about there every time:
It’s almost never a strike, yet batters keep swinging, and Ziegler is able to pound that one corner of the plate, low-and-outside to lefties, low-and-inside to righties. Of the 118 pitchers who threw at least 200 changeups last year, Ziegler’s had the sixth-highest swing rate, and the third-highest ground ball rate.
This is how Brad Ziegler gets people out with an 84 mph fastball; by actually doing it with a 77 mph change-up. And it’s why a side-armer can get lefties out, rather than being confined to the specialist role that almost all of his fellow drop-down pitchers are forced into. Ziegler might not have a big league fastball, at least from a velocity standpoint, but the development of his change-up has made him a very unique pitcher, and allowed him to get hitters to chase pitches out of the zone even without stuff that would be described as traditionally dominant.
So Ziegler basically breaks every mold you can think of. And he even breaks our models. His career FIP is 3.38, but his career ERA is 2.44, almost a full run lower. Part of that is that groundball pitchers get to count more of their runs as unearned because there are more errors on groundballs than on flyballs, so ERA systematically is biased in favor of groundball pitchers. A larger part of it, however, is that Ziegler has just been very good at stranding runners throughout his career, in part because it’s really hard to score a guy from second or third base on a groundball in a high-leverage situation, when the infield is often unwilling to trade a run for an out.
So Ziegler is about as unique as it gets, and unsurprisingly, the markets aren’t as willing to reward a guy who succeeds in a way that no one else can. There’s risk there, in a way that doesn’t exist with more traditional players. And there’s probably some extra risk with Ziegler, given that the league has talked about raising the bottom of the strike zone in order to alleviate the pressure for guys to swing at pitches they can’t hit. Ziegler would be hurt by that change more than anyone, in all likelihood, so if the strike zone really does change in 2017, perhaps his approach won’t work quite as well.
Given his age and unique skillset, it’s not that surprising that Ziegler looks like something of a relative bargain compared to some of the other reliever contracts we’ve seen this winter. When we focus on what Brad Ziegler can’t do — throw hard — then we miss what he can do; get people out. He won’t do that forever, but in this market, $17 million for a durable workhorse who keeps runs off the board seems like something of a bargain.

I live for this stuff. This is just how it is when you’re an oddball.
Not that I disagree with the overall premise of the article, but I think that the use of RA/9 WAR is a little disingenuous here.
It seems like cherry-picking to make Ziegler sound better than he is for the sake of the article. Fangraphs has its own model of WAR, so one would think that the managing editor of said publication would use it for support in an article written for its site.
Presumably, Dave didn’t cite fWAR because Ziegler’s only been worth about 2 fWAR in the timeframe–a substantive difference from 5.1. I don’t think it’s necessarily a problem, but if you’re not going to use fWAR (which I think Dave would generally say is better) then you should explain why you’re not using it.
It’s also possible that Dave used RA/9 WAR because you can Play Index WAR (I think) but you can’t run fWAR in the splits leaderboard. If that’s the case, I get it, but I still think that a rationale should be provided for RA/9 WAR.
If you’re going to make a claim that Ziegler’s going to be undervalued because he’s incredibly strange in his way to being effective, there’s no need to conflate his value. Just cite his wOBA, because that point’s legit.
Don’t get me wrong–it’s a cool article and the analysis is fascinating, but what I mentioned above struck me as weird.
If the ERA & FIP don’t match up then over a significant sample size you can say that FIP doesn’t properly value Ziegler’s skill. So fWAR doesn’t paint a clear picture. I don’t see the issue with using RA/9 WAR – it was created for cases like this, where fWAR doesn’t match up with what we’re seeing. Cameron even admits that Ziegler breaks the FIP based model, which is why he doesn’t use it. He explained very clearly why he wasn’t using it. In 600 innings Ziegler has a career 60 ERA- and a career 84 FIP-, a large enough gap to recognize that FIP doesn’t properly value Ziegler’s production.
I agree, but his discussion about FIP is tucked away much later in the article.
Your point is basically what I would like to have seen early on. Again, it’s not a major issue, but it is a way to tighten up or further lend support to an argument without a lot of effort.
I think it’s implied: the caveats of FIP are well-known to readers and the allusion of low-strikeout rates and the mention of Ziegler being a “freak” are very clear indications that a FIP-based analysis is not appropriate here.
WAR in general just doesn’t work for relievers, and I look forward to the day when articles like this one have another, more appropriate counting stat to cite. fWAR is particularly bad with pitchers like Ziegler, since he doesn’t get strikeouts and doesn’t induce popups, so he looks terrible by Fangraphs’ model. Obviously, that model is doing a bad job of predicting his results, so RA9-WAR (strictly giving him credit for results, assuming they’re all earned) is somewhat more accurate, but still obviously flawed.
Ugh. The replacement level for starters and relievers needs to be harmonized yesterday
RE24-WAR might be a good place to start. I’d have to bet someone’s already taken a stab at it.
Great column. But I think there’s another factor here. Ziegler mainly walks the guys that can hurt him, i.e., lefties. LHBs have more than twice the walk rate of righties against him (50% higher unintentional, 10 times higher IBB). He gets away with it partly due to the best GIDP rate among active pitchers, by far.
Calling him a side-armer “who can get lefties out” seems a bit strong. His career slash line against LHBs is .271/.365/.392, for a .757 OPS that’s almost 200 points higher than RHBs. The gap is smaller in recent years, but that’s also a smaller sample. I think it’s more fair to say that he manages a known weakness.
This is the first time I’ve seen it mentioned, so I’m not sure if there is data to go with it but, I always thought throwing a changeup was easier submarine. I briefly threw submarine at the end of high school, and the changeup was the only pitch (other then FB) that I could command well and that had discernible movement while doing so.
Eno mentions that with a changeup you usually pronate, but its very minimal. You don’t physically rotate your hand to the left(its basically impossible while throwing, at least in the same way you would do for a breaking pitch), rather it is a result of what I was taught as “show the O”. Where your you simply by the way you are turning your arm, create a small amount of pronation in the follow through mostly by exerting more pressure on the left side of the ball. Similar to the way you would follow through a curveball, but without twisting your wrist.
Now, the above applies though when throwing over hand, where the top of your hand is more or less facing “up”. Its really easy to twist to the right, but as I said earlier, its pretty much impossible to get true pronation, because your hand is already just about in that position.
However, when throwing submarine, your hand is now more or less facing “down”. Now the exact opposite is true. You can pronate very easily, and on your follow through, with most pitches your arm will naturally pronate. To supinate would now be quite difficult.
Just a couple quick thoughts. As it always seemed to me like the changeup came incredibly naturally while throwing submarine.
Referencing someone that retired 28 years ago might not be terribly pertinent, but when I watch Ziegler, I am always reminded of Gene Garber. Garber was sidearm, not submarine. And his changeup was more straight (in my memory), than a big dropper. But, especially versus lefties, he had to throw just about as many changes as fastballs, with the occasional slider. And his splits were pretty even (in some of his best years, he even had reverse splits).
I don’t remember Garber’s stuff, but he was fun to watch and like Ziegler he was perennially underrated.
Thanks, Dave! I love it, great supporting info/data/stats/charts. I put together my own spreadsheet using more than a dozen metrics. I am fascinated by trying to unpack performance/metrics. What I found was similar. In my personal rankings of effectiveness/dominance among 2016 relievers, here’s a cluster (lower number is better):
• 10.5 Alex Colome
• 10.6 Wade Davis
• 12.1 Derek Law
• 12.8 David Phelps
• 13.1 Kelvin Herrera
• 15.3 Brad Ziegler
• 15.8 Dellin Betances
• 17.6 Michael Lorenzen
(For reference, the historically elite basically “break” my model:
-8.5 Britton 2016, -7.6 Eckersley 1990, -4.7 Gagne 2003, -4.2 Kimbrel 2012, -2.6 Uehara 2013. In 2016: 2.2 Miller, 4.0 Chapman, 4.2 Jansen, 5.0 Otero, 5.9 Melancon).
Do my 2016 reliever rankings seem reasonable?
“This is how Brad Ziegler gets people out with an 84 mph fastball; by actually doing it with a 77 mph change-up.”
This is basically the Keith Foulke formula for success, just translated to a submarine delivery.
Some great gifs of his pitches

The one that he throws to Encarnacion is the kicker. It stays up at the top of the zone but outside and Encarnacion just flails at it because it is so slow.
The ball just umps in those GIFs. Totally feel for the batters.
are there any anti-zieglers? guys who walk more than they should, given their general pounding of the zone?
