How Good of a Weapon Did Drew Hutchison Find?

Have I mentioned lately how helpful the chats can be when it comes to finding things to write about? You guys don’t know how valuable you are. Dozens upon dozens of questions, if not hundreds upon hundreds, and out of those questions, longer posts can occasionally germinate. This is one of them! Because I’ve noticed a recurring kind of question about Drew Hutchison, and how much he might be capable of in 2015.

Pulling an example, from earlier January:

Comment From BJ Birdie
Drew Hutchison had a 26% k rate and 7% walk rate in second half of 2014 after changing his slider (slower, more vertical movement), what do you think his chances of a major break out are in 2015?

Dave Cameron: I think the research has shown that trying to use second half performance to predict future breakouts is a fool’s errand.

Dave’s right, of course. The smart thing to do is to always bet against a breakout, as foretold by an encouraging second half. But that’s also boring, and one figures encouraging second halves can sometimes mean something for the season to come. We’re all just here to analyze, right? So, let’s do some analysis. What on earth was the deal with Drew Hutchison’s slider?

Turns out this is really easy to spot. We’ll turn to Brooks Baseball, as we usually do. Hutchison has thrown a slider all along, but late last year, something was different. A plot of average game velocities:

You see the slider dropping down to the far right side. This is maybe even more apparent when we look at a plot of average vertical movements:

hutchisonvertical

That’s abrupt. All of a sudden, Hutchison’s slider was a tick or two slower, and it was dropping another three or four inches. It had bounced around a little bit before, but never like this, and never with so much consistency. Something was different. Hutchison, it seems, made some kind of tweak.

Or he just figured out almost overnight how to deliver his breaking ball with far greater consistency. Now grabbing images from Texas Leaguers:

HutchisonPitches

It’s easy to see the green blob move. But it’s not like things changed dramatically — there’s overlap between the two blobs, such that the sliders Hutchison was throwing down the stretch last year did have some precedent. Earlier in 2014, Hutchison did throw some sliders with a lot of vertical break. But toward the end, he threw them almost exclusively. Through August 17, 55% of Hutchison’s sliders had a vertical movement reading below 0, according to PITCHf/x. Afterward, 99%. That’s not the kind of thing that can be explained by coincidence.

Here’s one of Hutchison’s finest sliders from that final stretch:

HutchisonSL3

That’s a beautiful pitch. A seemingly unhittable pitch? But here’s a similar slider, from June:

HutchisonSL1

And here’s a completely different slider, from the same game:

HutchisonSL2

Because there was precedent, I don’t want to say that Drew Hutchison picked up a new pitch. He’d thrown those late-season sliders before. He’d just never thrown so many of them. He all but eliminated the harder sliders, the borderline cutters. What’s odd is that Hutchison hasn’t talked about this at all, to my knowledge. I just find some generic remarks about better consistency. But, I also haven’t consumed every single piece of Blue Jays media since August, so maybe I’m missing something. Toronto opponents had their eyes open:

“His slider was really good today,” said Teixeira, who hit a hanging changeup for his double, Hutchison’s only mistake over the plate. “We really hadn’t seen that before.”

From Chase Headley, perhaps meaningfully:

Said Headley: “Just seemed like he had a better slider than I’ve seen from him in the past and on video. He pitched a heck of a game and didn’t give us a whole lot to hit.”

It’s clear, from those quotes, the Yankees were unprepared for the slider Hutchison was throwing. They’d seen him plenty before, and they’d seen him throw sliders plenty before, but on August 30, the slider was different and extremely effective. Hutchison was worse when he faced the Yankees again three weeks later. I don’t know how much to make of that.

I think I accidentally skipped right by the very reason this is so interesting. The PITCHf/x plots show a significant change between Hutchison’s starts on August 17 and August 24. Why don’t we go ahead and split his season into bits?

Through August 17

  • 122 ERA-
  • 104 FIP-
  • 13% K-BB
  • 80% Contact

From August 24

  • 84 ERA-
  • 78 FIP-
  • 26% K-BB%
  • 70% Contact

That’s a gigantic change in performance. And along with the different slider characteristics came different slider usage patterns. First, he threw the slider 21% of the time. Then, 31%. First, he threw the slider 33% of the time with two strikes. Then, 45%. The slider became the preferred putaway pitch against both righties and lefties, despite its reputation as a pitch with a broad platoon split. Pitch patterns don’t change randomly. Not like this, not over a handful of games in a row. Hutchison developed a lot more confidence in his slider. He knew what he was able to do with it, and he was having a lot more success keeping it consistently down and mostly out of the zone without being too far out of the zone.

So Hutchison polished his slider and became more consistent with it over the course of seven starts or so. He immediately increased his level of trust in it, which allowed him to back off some from his changeup, which has never been a plus delivery to lefties. Between a low sharp slider and a high fastball, Hutchison mostly succeeded with two weapons. The changeup is still present to keep hitters honest.

Combing through the Baseball Prospectus PITCHf/x leaderboards, I noticed you can split by month. I looked for sliders thrown by right-handed starters last September, and I set a minimum of 50 sliders thrown. Hutchison’s slider has the lowest average vertical movement. The only other slider close: Jason Hammel‘s. Interestingly, about Hammel’s slider:

hammelpitches

Hammel’s slider also experienced a midseason change in vertical break. It’s a decent comp for Hutchison’s, in terms of velocity and movement. Like Hutchison, Hammel threw his slider pretty often against left-handed hitters. And he was a lot better against lefties in 2014 than he was the year before. They say the slider isn’t a great pitch for righties to throw to lefties, but that’s a rule that has to have exceptions.

The question is, what now? Hutchison was absurdly good after he started exclusively using his slower and bigger-breaking slider. That’s the encouraging bit. He did finish strong, and it does look like a quality breaking ball, visually. Hutchison’s increased confidence in the pitch can’t be written off. On the other hand, there are two things. For one, who’s to say Hutchison’s slider will be so consistent again in 2015? And for two, now teams will have had more of a chance to prepare. The Yankees were caught off guard in August by Hutchison’s breaking ball. They were more successful the next time they met. Players in the league are always adjusting, and adjustments back don’t always happen immediately. There can be a delay, and perhaps, in Hutchison’s case, the word is out that his slider has a lot more consistent depth.

As long as Tyson Ross exists, there’s reason to believe righties can be effective against lefties leaning heavily on a slider. Hutchison demonstrated his own ability through seven late-season starts. It’s absolutely right to be encouraged. And it’s absolutely right to be curious. Hutchison’s slider might just be a part of him now. And in 2015, opposing teams get to take that into consideration. Somewhere in August, Drew Hutchison figured out his breaking ball. Now it’s on the league to try to figure out Drew Hutchison.

Jeff made Lookout Landing a thing, but he does not still write there about the Mariners. He does write here, sometimes about the Mariners, but usually not.

I hope your hands don’t fall off from all the writing you’ve been doing over that past couple of days, Jeff. Great stuff, as always!

“Or he just figured out almost overnight how to deliver his breaking ball with far greater consistency”

as a huge fan of hutch since he started dominating the low minors, I have to give my vote for “consistency” being the answer. he’s always flashed a great slider, but it dissappeared too often. though admittedly some of those gifs there probably do show a flat out better slider than we’ve seen in the past.

I’d love to see how this compares with his rookie year before TJ. we can see how his velocity started down this year but ticked back up to normal as his arm got loose/stronger, and I wonder if something similar is going on with his breaking ball.

either way his struggles vLHP were starting to become a concern so thanks for this encouraging article.

good article, but the gratuitous Scherzer comp kinda ruins it.

Bless you, Jeff. Bless you, FanGraphs. And the $5.99 for FanGraphs+ was the best money I’ve ever spent. Or at least since I could buy 5 boxes of wax packs for the same money!

BTW are you guys contemplating an ad-free subscription?

One of our writers spotted this too and we wrote about it earlier this month: http://www.bluebirdbanter.com/2015/1/5/7489853/drew-hutchisons-new-and-improved-slider

I had a conversation with Andrew Tinnish and he was not aware that Hutchison had developed a “new pitch” per se, thinking it’s more an arm angle change. But of course, he could’ve been hiding something.

I was also going to come link back to this article because I felt I’d already read it, but I see it’s already been done twice, heh.

I was like, “Hey, I recognize those graphs!”

For the record, I asked the question after reading this article and will give it “original credit” for the idea.. this authour there does great work.

Really appreciate seeing the question answered from a different perspective.

Great article, though makes me hate Cameron more. What a dismissive response to a legitimately well founded question. Cheers to you Jeff for picking up the baton on it.

Sure, some arbitrary data set isn’t a predictor of future performance, but when its supported by scouting, there is reason to believe there is reason to at least dig further. To view players as just static skillsets is so simpleminded and unproductive.

My biggest takeaway is that Dave has to be the one of the most incredibly rude people I’ve encountered (/read?). I’m not sure where the contempt for his readership comes in, but it makes me not want to read his otherwise excellent work. It is very disappointing.

The second is that this article is top notch. Really enjoy your work, thanks for sharing this.
