Clayton Kershaw New Trick Status Update
Clayton Kershaw is starting Game 1 of the NLDS for the Dodgers, and that’ll be a welcome sight for a team that wasn’t sure if he’d even be able to make it back for the playoffs at all. There’s no replacing Kershaw’s presence, and there’s no replacing Kershaw’s stuff. When Kershaw returned from the disabled list, he brought his stuff. And it turns out he even brought something extra!
In a start against the Rockies, Kershaw twice dropped his arm slot. That wasn’t much, but it was something new, and I put something together on the subject. Kershaw was inspired to mess around by teammate/apparent superstar? Rich Hill, who’s made a habit of varying his looks. It turns out Kershaw used to throw from a lower slot in high school, so the twist didn’t come completely out of nowhere, but it was still worth wondering after that game whether Kershaw would re-visit the trick. It could’ve easily been a one-off.
We can say now the trick has been re-visited. Maybe it’ll be a two-off, but Kershaw dropped his arm five times in his last start against the Giants. This is now something for the Nationals to be aware of, and this is now something for you to look out for from home.
Time to run through all the relevant video clips. You know how Clayton Kershaw normally throws, right? Let’s say you don’t. This is how Clayton Kershaw normally throws:
Very much over the top. That style gives Kershaw a certain deceptiveness, and it’s also where he gets his true 12-to-6 curve, and straight rising fastball. If you just step outside to throw a ball around, it might hurt you to try to throw that over-the-top, because it doesn’t feel like such a natural slot, but Kershaw has made it work and mastered it over his years. Clayton Kershaw is an overhand pitcher. Here now are five pitches he threw to the Giants from more of a three-quarters slot:
I still don’t love the way Kershaw finishes this delivery. He has a lot of body momentum seemingly carrying him toward first base. But there’s no denying the velocity, and you can see how this would take a hitter by surprise. One is inclined to want to give Kershaw the benefit of the doubt. To run through a few quick observations: You’ll see that Kershaw has done this against both lefties and righties. Interestingly, all seven times Kershaw has dropped down so far, he’s done so in two-strike counts. He’s also only thrown fastballs. Three have been taken out of the zone. One was taken in the zone. One got a whiff, one was grounded out, and one was hit in the air. It’s a sample size of only seven, but it’s five in a game, after it was two in a game, after it was zero in so many games.
Through September 19, Kershaw hadn’t dropped down. Here are all of his pitch velocities and spin axes:
Here is what’s different, over the past two turns:
It’s subtle there, but it’s less subtle in the spreadsheet. Kershaw’s low slot gives him good velocity, and, most importantly, there’s this: his average fastball has 0.7 inches of horizontal break. It’s almost perfectly straight (along that plane). When Kershaw has dropped down, his fastballs have averaged 6.9 inches of horizontal break. So that’s a half-foot of run, which Kershaw otherwise doesn’t feature. The drop-down fastballs also have three fewer inches of rise, because they just move in a different direction. It is, effectively, a brand-new pitch. It’s a fastball that Clayton Kershaw has never thrown.
What you’re free to question is the effectiveness. Kershaw’s lower slot hasn’t led to pinpoint location. It still might; watch for it today! But you also wonder if it might be too easy of a giveaway. As I mentioned earlier, the seven times Kershaw has dropped down, he’s thrown seven fastballs. Rich Hill throws both fastballs and breaking balls when he drops down, so there’s nothing to predict. That just doubles the size of his repertoire. With Kershaw, you might see that arm slot and know a heater is coming, a heater with tail to it.
I can’t speak to that too much. I don’t know if Kershaw can throw a decent breaking ball from down there. I don’t know if he’s been specifically waiting to do that until a playoff game. The size of this sample is seven pitches. So I can’t wait to see what the Nationals see. And ultimately, even if Kershaw does only throw low-slot heaters, that’s still one more thing you have to prepare yourself against. You might identify a low-slot heater is coming, but up until that instant, you don’t know if it’ll be an overhand heater, slider, or curve. This is still Clayton Kershaw. Kershaw was literally the last starting pitcher on the planet who needed to do something to make himself more difficult to face.
But, you know what they say, the best players are never satisfied. Kershaw knows a new twist probably wouldn’t make him worse, and maybe it’ll give him an edge in a critical at-bat or two in the coming weeks. He might only throw low-slot fastballs, but he could conceivably mix in a low-slot slider. He might only throw low-slot two-strike pitches, but he could conceivably mix in a low-slot first pitch to steal a strike. The promise here is all about uncertainty, and this is just one more way that the Nationals might struggle to do any damage.
Or, the low-slot pitch could disappear entirely. Maybe Kershaw has already decided to put it in his back pocket. But the mysteriousness already exists, because of what he did his last two times out. Nationals hitters have now heard about Clayton Kershaw dropping down. At least for now, it might not even matter whether he does it at all. The seed has been planted, and the mind of a hitter facing Kershaw already has plenty of plants.
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.


NL hitters hate it!
What is that bottom/middle pitch in the first plot?
What is that pitch a few spin clicks to the right of his FB cluster in the second plot?
First one has to be that eephus he threw. 180 degrees is straight over the top and it’s like the slowest thing he’s thrown. The other one seems to be some sort of slider with sharp downward bite, but I don’t know whether it was a mistake or some other experiment.
Kershaw has dropped down a few times so far and it hasn’t been all that successful for him. Three times already against Bryce Harper, and those have gone for two balls and a line-drive single.
An announcer (it may have been Harold Reynolds, gasp!) pointed out, correctly, that he has only thrown fastballs from that angle so far. As long as that is the case, the low slot essentially serves as a really obvious way of tipping pitches. He also, by coming around more and staying back less, seems to have a hard time finishing around and hitting the glove side of the plate (catcher’s left), which is where he normally lives.
He has been very successful to Bryce Harper with curveballs and fastballs away, and so instead he dropped down, signalling a fastball, and couldn’t finish it, leaving it middle-in, and, predictably, Harper hit it on a line.
PS: I could have sworn he hit it over 100 mph but Statcast said only 88.8 (which now ties back to a thing that Greinke said a while ago that inside pitches tend to have lower EV but higher batting average. I think pulled balls tend to look harder hit for some reason. Anyway, it was a .747 expected batting average.)
Kershaw playoff Era is near 5 with 70 innings pitched so what does this even matter…everyone can blame Puig or another scapegoat for the Dodgers being unable to win a playoff series but it sounds to me like they think they can depend on Kershaw and they cannot. 4 years in a row
70 innings is not a significant sample size.
ERA is not a good stat for telling how good a pitcher is.
You are not telling me anything I don’t know buddy. I guess ERA just matters in things like wins and losses and stuff nothing too significant especially in the playoffs ( I’m laying the sarcasm on real thick now I hope you’re picking it up) …so 70 innings is not a significant sample size then I guess you can’t say Mad Bum is a great postseason pitcher. No no can’t say it need more info..
The biggest difference between the MadBum start, and tonight’s Kershaw start (because neither had great command): Bumgarner’s middle-middle mistakes became pop ups at a crazy rate, Kershaw’s got lined, on of which bounced off of Turner’s glove and brought in two.
Then why weren’t those unearned runs? because the ball blasted past Turner so fast he never really had a chance.
Correct, you cannot definitively say Bumgarner is a great postseason pitcher, depending on how you define “great”. He has had great results in the postseason, but pointing that out is tautological. You have to do more work to show what, if anything, that says about Bumgarner the pitcher and Bumgarner the man.
He PS xFIP is slightly worse than his career value and his PS FIP is slightly better, neither variation significant. However, his PS ERA is 1 run lower than his PS FIP. Hm, that sounds familiar:
Bumgarner, postseason:
IP: 97.1
ERA: 1.94
FIP: 2.99
Bumgarner, 1st half of 2016:
IP: 129.2
ERA: 1.94
FIP: 2.93
And then… what happened in the second half of 2016? Basically expect what DIPS theory predicts, he regressed into more or less what his FIP was.
So, my question is, if the first half of this year didn’t establish him as a super clutch FIP-beater, why should we treat identical postseason results any differently?
I know that question was pointed towards Bumgarner only (kinda) but what do you define as great? I think a 82 FIP- (Bumgarner) is great (Per FG FIP- glossary). Now when I say that, then I have to define Kershaw (83 FIP-) as great too. That being said, I think Kershaw takes a hit possibly because I/fans expect more. We want/unfairly expect to see regular season Kershaw. Bumgarner pitches great in the RS (85 FIP-) and he does a little better in the PS (82). Kershaw pitches excellent/historic in the RS (65) and “just” great in the PS (83). He set his standard too high. Despite the fact they have pitched similary, things have not gone Kershaw’s way while Bumgarner has caught breaks.
Both of their PS stats are favorable compared to PS “heroes ” of the past (Schilling, Pedro, R. Johnson, Smoltz, Beckett, J. Morris). But people remember those performances because they won (not that Kershaw won’t be remembered). People are wondering if Kershaw is the greatest pitcher who they have ever seen. I just hope that doesn’t go “yeah, but…”.
“Correct, you cannot definitively say Bumgarner is a great postseason pitcher, depending on how you define “great””….oh great you’re “that guy” keyword was postseason in my post not sure what tangent you’re on.
Go on, list the pitchers who have been to the playoffs 4 years in a row.
i can name one who if he didn’t pitch his team would of most likely done better: Clayton Kershaw
