My Best Guess at Chris Archer
Chris Archer isn’t where he wants to be. He’s made four starts this season — in two of them, he’s allowed three runs, and in the other two of them, he’s allowed six runs. One of the especially bad starts came Wednesday, and now Archer stands with baseball’s fifth-worst ERA, and baseball’s sixth-worst FIP. Archer so far has been mostly dismissive of his struggles, but given how he also ended last year on a pretty flat note, fans are paying close attention. By no means would concern be unwarranted.
One certainly shouldn’t be too concerned. This is something we can say without even going too deep. While Archer has some ugly numbers, he also has a top-20 xFIP, owing to his high rate of strikeouts. The stuff is still there, for the most part. And while there have been too many hits, Archer hasn’t shown any decline in contact rate. It’s still not easy to get the bat on the ball, and as long as Archer is getting whiffs, he stands a good chance of getting straightened out.
You just can’t say this has all been nothing. Archer himself would tell you he hasn’t executed. Not with sufficient consistency. He hasn’t located the ball like he’d like to, and that’s made him vulnerable. When the location goes, you can blame something physical, or you can blame something mechanical. I trust that Archer is healthy, so I’m thinking about mechanics. And I do have a guess at what’s been wrong. To repeat: this is a guess! I am not Chris Archer, and we’ve never even emailed. If we’ve ever been in the same room, I sure as shoot didn’t notice. What follows is just one thing I have noticed. Put however much stock in this as you want.
Put simply, Archer was great for a while last year. Then his performance declined, and then he had the start to the 2016 season he’s had. That’s the general outline of what’s taken place. Now, there’s a pretty important issue with any mechanical analysis, for a pitcher or for a hitter. Pitchers and hitters go through their mechanics dozens or hundreds of times, and individual captures or screenshots don’t say anything about consistency. You don’t want to put too much trust in anything where N = 1. For what’s below, know that I’m just showing you a small selection of what I observed. I don’t want to overwhelm you with images. What I’ll talk about, I did see pretty consistently. That doesn’t mean I’m right! It just means what it says.
So, here’s Chris Archer throwing a pitch early in 2015:
Yeah, I know, it led to a bases-loaded walk, which is a bad outcome to highlight. But I think this was a good pitch, and an excellent take on the hitter’s part. So Archer did execute, I think. I’ve obviously slowed this down, and I want for you to pay attention to Archer’s front foot, or plant foot. Everything should look pretty ordinary. There’s nothing to compare to. Here’s Archer now from a short while back:
What I’ve noticed is subtle, as most of these things are. Again, watch the front foot. Go back and forth between clips if you have to. Pause them and compare if you like. In the first clip, Archer’s foot comes down flat, and he plants it right in front of his back foot. In the second clip, when his foot comes down, his toes are up. He lands more on his heel, and while in general Archer still plants his front foot right in front of his back foot, the alignment isn’t the same. Archer’s feet are more closed off.
David Laurila actually just talked to Archer in Boston. Here’s his response to a question about whether anything is different mechanically in the lower half:
“It wouldn’t be a conscious thing. I think my mechanics are pretty much the same.”
Everything does look so similar. It’s the same throwing motion, but with just that little difference in the landing foot. It’s the kind of thing that can just fold itself in over time, by accident, but a change to the front foot is a change to the stride, and every pitcher knows the stride is important. Here’s Archer when planted, from early in 2015:
I like to look at clips from Tampa Bay home games because of the mostly dead-center camera angle. This is ever so slightly off-center for some reason, but here you can’t even see Archer’s front foot. Here’s a recent image:
There’s that foot. You can see the heel. Here’s another recent image, just because:
Again, you see the heel, as Archer hasn’t swung his front leg as far around as he used to. We’re talking a matter of inches, so it’s not like all of Archer’s momentum is going toward third base or anything, but think about how much goes into delivering and executing a pitch. Everything has to be almost perfectly precise. When you go even a little off-line, it makes sense that your location could suffer. Some pitchers, granted, manage to get by because they’re just used to this:
I find that picture to be absurd, but the guy makes it work. A number of pitchers throw a little across their body just because that’s how they’ve always thrown. But for Archer, this seems like a little change. With a slightly more closed stride, he still looks like mostly the same pitcher, but he’ll leave some fastballs and sliders up. Sometimes he’ll over-grip and release too late. He’s not working in perfect alignment with the catcher, meaning there are forces pulling his pitches in other directions.
One more small group of photos. Here’s Archer at release, early in 2015:
Compare that to a picture from later 2015:
The easiest way to visualize this is that in the second picture, Archer’s feet are overlapping. Here’s a recent picture:
Same thing. Here’s another recent picture:
Same thing. It’s very subtle, and very easy to miss, but it’s a difference of a few inches, plus a fraction of a second if Archer is now planting his foot sooner. Those little changes can have profound effects on pitch execution, given how small the zone is, and given how much smaller the target area is. Even a wilder version of Archer is hard to hit. That’s been made abundantly clear. But the hitters like anything that makes the job any easier. If Archer doesn’t hit his targets as often as he wants, he’s going to be worse. That’s the truth of it.
It is not my stance that this is without question the matter with Chris Archer. I am completely open to being wrong, and solving problems like this is difficult. But if someone were to ask me, “what’s wrong with Chris Archer?” this would be my best shot at an answer. This is my guess, and if it’s right, it should be totally fixable. It would just take correction and reps. Let’s all of us check back in a month and a half.
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 want to see it, but I don’t see it…
I see it. Of course it’s difficult to definitely conclude there’s something here – we know the camera angles tend to be inconsistent and could be creating an optical illusion. But I can personally attest that very small changes to stride length and timing can have massive effects on movement, velocity, and command.
I think you are on to something, Mr. Jeff.
3 things about that cross-body throwing LAD pitcher picture:
1. Who is that?
2. Ouch
3. Cueto being allowed to bat in the bottom of the 5th with runners on 1st and 2nd after he’s already let in 6 runs?
Ouch again.
3 (cont)…… in a tied game with 2 outs!
Louis Coleman!
I guess Coleman throws that way because he was born with a foot on his right leg and a hoof on his left one.
And his left ankle looks very weak just above his hoof. Hopefully it doesn’t break under the weight of his delivery. After all his hard work to get back to the majors, it would suck if the Dodgers had to put him down.
Just neighing.
Haha it does kind of look like a hoof in that shot! From the look of that mound, I hope he’s a mudder.
So this has been his Archer-les heel? (I am almost certainly not the first person to crack this joke.)
Lessening the stride length by just a couple inches will create big problems. He’s effectively “short arming” pitches since he’s not able to finish his follow through because the leg is in the way of his arm. And because he can’t finish his pitches he’s leaving a lot of pitches up cuz he’s not throwing with a downward plane. He needs to yank the left side of his body through, bringing his left leg further left which will leave more room for his arm to come through and down. Right now he’s effectively shot putting the baseball.
Effectively is probably not the right choice of word for what he’s been doing.
in his very first start of the year versus the Jays, he appeared to tweak something in his right arm. the Jays broadcast caught it pretty easily, and though they are useless in many areas, they seem to have a good feel for when a guy is not right physically. Archer looked to the dugout but shook them off.
lots of walks, velocity down a bit, possible mechanical issues… how different is this than the Felix Hernandez story? he’s had pretty high usage of one of the hardest, nastiest sliders in the game for several years now. bound to catch up with him no? even if he’s not feeling something on a day-to-day basis, it doesn’t mean that there isn’t something seriously wrong with that arm.
I know it could just be due to the state of his delivery in the pics, but it also looks like his elbow is much more bent in the recent shots, compared to being straight and extended last year.
Yes. Yes it does. That could mean three things:
1. It’s a slightly different point in his motion
2. His arm is bent differently now.
3. The camera is a bit more in RF than it was last year, and that would actually mean his stride is even shorter than it appears
I think it looks like number 1 is a strong possibility, he looks more upright in the pics from this year.
This really should be forwarded to Archer and/or the Rays.
Nice work, Jeff.
Great article
I happen to like Chris Archer a lot, both as a pitcher and a well-spoken addition to last year’s playoff broadcasts. I want him to do well, and I think Jeff is on to something.
I saw Archer pitch against the Red Sox this past week, and what I saw with his misses were fastballs left up and in and sliders pulled low and away. This is exactly what you see when a pitcher’s front foot lands to the left of a straight line connecting the rubber to the plate (or left of his normal landing point). Either way, it indicates that he is opening up, at which point his body tries to compensate in order to hit the correct location. He ends up throwing the fastball across the grain, and since the slider is designed to go low and away anyway, he pulls it even more so.
Velocity wasn’t his problem from what I saw. He was getting it up there at 95-96 after he got loose.
I believe Jeff is actually saying the opposite, that Archer’s delivery is closed as opposed to opening up, as his landing foot was landing more toward 1B last year, but this year is landing almost down the middle.
Correct.
Jeff, Great analysis. Great execution in explaination and photographic proof. Definitely looks to be a core reason for the “hanging slider in video two against the Indians where he wants to throw the pitch to the back foot or bury the ball into the back of the left handed hitters batters box.
Landing closed to the plate aka throwing across your body, even if very subtle, disrupts the arms ability to get through his arm slot/arm motion to his proper release point. This creates the throwing arm to lag behind the body, forcing the release point to become earlier and not as far out in front of his front foot as he normally would. This creates an inability to get his fingers on top of the baseball which the main component in creating correct/sharp spin and fast and sharp movement on the baseball, low in the strike zone or stronger command where ever the pitch is intended to go. I wrote about this after Matz first start after getting hit around by the Marlins on April 11th.
Thanks again, it was a great read! – Chris Zaccherio
Can you please do your next one on Shelby Miller?
Had this same issues as a pitcher in college. I closed myself off a bit and landed on my heal, which made me throw around my body. It is very fixable, but definitely explains why he’s missing with some key pitches. Great work Jeff.
I just think the type of motion he has is tough to repeat. He may be getting the same swinging strike percentage but making more mistakes that are being taken advantage of.
