Pitches Illustrated

This is an excellent little site/cheatsheet illustrating how various pitches look from the catcher’s batter’s perspective. These diagrams assume a right handed pitcher. For lefties, imagine them (roughly) in reverse. 

For extra fun, print this out and read Stu’s excellent piece on Strasburg’s opening day pitch selection. It looks like Strasburg’s new slider is part of a plan to start busting left handed batters down and in. Contrast this with Strasburg’s previous approach against lefties: the changeup running away from the batter. 

In old-timey pitch classification, this gives Strasburg both an “in-shoot” (slider) and an “out-shoot” (changeup) against lefties. If you’re a DC baseball fan and believe in baseball reincarnation, this is a good thing. Guess who else had this kind of repertoire?

The ball that bothered the Naps [Cleveland Indians, managed by Napoleon “Nap” Lajoie] yesterday from Johnson’s delivery was a fast high inshoot that broke just in front of the plate. He had all the Cleveland batsmen guessing on this ball. If it failed to break, it cut the plate at about the height of the batsman’s breast letters. When they swung at it, however, it seemed to lift over the handle of the bat. This ball, breaking properly, is practically impossible to hit squarely, and will fool the cleverest stick artist in the business. Johnson’s speed, of course, is a factor in all of his work, his curves taking their swing viciously just before reaching the batting area.

 

Not bad, Strassy. Learn from the Big Train.

Bad Company

Drew Storen has been optioned to AAA Syracuse.

This is a hard post for me to write, because I’ve been a huge Drew Storen fan since, well, ever. I’ve wanted him to succeed. I‘ve been a shameless Drew Storen apologist, even in the darkest moments.  But with Ryan Mattheus coming off the disabled list, and only twenty-five spots left on the active roster, someone had to go down. Drew Storen had an option year available. He has also had a disappointing year–so he had to be the one to go.

There’s going to be an awful lot written about Storen’s demotion, and even more said about it. The most pointed words probably come from fellow reliever and sometime roommate Tyler Clippard:

He hasn’t had to deal with a lot of adversity. He came up and had unbelievable stuff. He had success right away. Came in last year, coming off of a surgery, and pitched huge games for us in a  98 win season. Picked me up when I was struggling in September. Picked our team up in the playoffs. Had one bad game. Eight months later, you get to a point where he’s struggling and you turn the page on him, you send him down. It’s not necessarily turning the page on him because I think he needs to go down and regroup, get out of this environment, take a deep breath and regather himself.

You know by now that I don’t like getting into ballplayer’s heads. I sit in the upper deck. I’m lucky if I can track the movement of the ball, let alone look into a man’s heart, mind, or soul at that physical and psychic distance.

If Storen needs to get back to something, perhaps this chart has some of the answers:

This chart tracks the sheer number of swings and misses generated by each of Storen’s four main pitches: the four-seam fastball, the sinker (two-seam fastball), the slider, and the change-up.

Between 2012 and 2013, you will note the sharp increase in swings and misses generated by his changeup–a pitch that he began throwing far more often. There is a corresponding drop in the number of swings and misses generated from both fastball varieties and from the slider–with the largest decline coming from the slider.

This puts in graphical form something that even upper-deck dwellers have begun to suspect: Storen’s slider–memorably described by Bob Carpenter as the “killer slider” on so many occasions–has lost much of its lethality.

If we take the number of line drives as a rough proxy for the number of times batters really squared up and made good contact, that should tell us more. Let’s look at the total number of line drives generated for each ball in play for each pitch, from the second half of 2012 through this month:

Oof. Look at that. Sharp increase in hard contact off the slider. A look at his pitch selection data reveals that he’s throwing, proportionally, more sliders than ever:

So what we have here is a pitcher throwing more of a pitch that is ever less successful. Storen seems to want to throw that slider a lot, even if he knows that it’s getting hit hard. This is not a recipe for success. What’s gone wrong with Storen’s slider?

First: it’s not as hard as it used to be: notice that it’s about 2 miles per hour slower this year than it was last year:

Second, it’s dropping a bit more: surely this is good? Yes and no. Some of the increased drop will be due to the drop in velocity we’ve already seen. If we look at it’s dragless vertical movement plus gravity, compared with release velocity, we note that the slider drops about as much as it ever did–except that now it’s just, well, slower. That’s not good. 

 

 

 

Third, it’s not, well, sliding as much as it did last year:

If there’s any hope here, it’s the emergence of Storen’s change-up as a weapon. Notice: it’s the only one of his pitches that is fooling more batters this year, rather than fewer. That’s something positive. And if Storen hopes to come back to hear the adoring crowds at Nats park howl his name ( DROOOOOOOOOOOOOOOOOOOOOOOOOOOO! ), then I hope for his sake that he goes down to Syracuse and works on the fastball/changeup combination that seems to be working.

While he’s down there, he could probably stand to work on his slider. He was a much more effective pitcher with a harder, more violent, more lethal killer slider. This year’s softer, milder slider has gotten him into trouble.

And whenever he’s ready, I’ll be back in the upper deck, waiting for him to return as the fine reliever that I know him to be.

 

[Edit: I had initially mis-interpreted the vertical movement graph, which led me to look at dragless horizontal movement plus gravity, which actually underscores the point better. Storen’s slider is dropping as much as it used to, but not because of any breaking motion…it’s dropping just becuase it’s slower. That’s an appealing target for a hitter, no?]
