A Little Fun With Erik Bedard And PITCHf/x
I don't have anything mindblowing to say about Bedard's performance this afternoon (good stuff, weak command), but it's been a while since the last time I did this, so I thought I'd throw up a couple charts.
You've seen both of these before. The chart type, anyway. 96 of Bedard's 99 pitches were captured by PITCHf/x, with 71 of them coming against right-handed hitters. During these at bats he threw 46 fastballs, 24 curves, and one changeup (not shown). He spent a lot of time around the edges, which is usually a safe place to be when you're trying to avoid solid contact, but because he didn't have his best command he also spent a lot of time just outside of the zone. He did do a good job of keeping his fastball away from the middle of the plate. Bedard's fastball had strong velocity (91.8 average, topped out at 94), but it's a pretty straight pitch, and not the kind of thing he wants to put in the wheelhouse. He can get away with catching more of the plate with his curve since it's more difficult to hit, but even there he stayed around the edges. He seems to be fond of trying to get high-away called strikes and low swinging ones. The results weren't necessarily there today, but the intent certainly was. Dustin Pedroia just kept spoiling his best pitches.
Against lefties, Bedard threw 16 fastballs, eight curves, and one slider (not shown). You can clearly see him trying to stay away, as he didn't throw a single pitch in the strike zone on the inner half. He did center three fastballs, each of them coming early in at bats (two first pitches, one second pitch), but two of them were fouled off and Brandon Moss swung through the other. Once again you can see him trying to use the curve to induce weak contact off the end of the bat. With the fastball generally being up and away and the curve being down and away, it must've been difficult for left-handed hitters to distinguish between them, as they would've been in the same area until the curve fell off the table at the end. Interesting that, against lefties, Bedard didn't throw a single pitch below the knees. Small sample size warnings apply, but based on this it seems like he'd rather see lefties flail than swing over something low. Come to think of it, the only pitches he threw below the knees against righties were curves. I wonder if he's had some bad experiences with low fastballs in the past.
To change course a little bit, now I want to show you something that I first saw used by Josh Kalk over at THT, just because I think it's super cool. The following is what Erik Bedard's average fastball and curveball from this afternoon look like from the side:
...and this is what they look like from above:
PITCHf/x starts tracking 50 feet away from home plate, so 50 feet is what I'm sticking with. In the first image you can clearly see the big hump in his curveball, and over its final 40 feet in the air it dropped four feet nearly straight down. Put another way, Erik Bedard's average curveball this afternoon dropped from the batter's head to the batter's knees. Try reacting to that in half a second. (Bedard's curveball flies for ~0.5 seconds, while his fastball is closer to 0.4). You can also see that his curveball release point was a little higher than the one he used for his heater. From what I can tell, this has been a pretty consistent phenomenon across starts dating back to last year, and gun to my head I'd say this is how Bedard compensates for throwing a curve with so much break. He releases it a little higher so that it doesn't always just end up bouncing in the dirt. It seems like this might be a bit of a pitch-tip, but given how successful he was in 2007, it doesn't strike me as being a major concern.
The bottom image is a little more difficult to understand, but just think of it as a bird's eye view. 0 on the y axis refers to the center of the plate, so the pitches come from ~2.6 because Bedard is left-handed and therefore releasing on the left-hand side of the rubber. You can see his fastball with a little tailing action; at first it looks like it'll end up inside on a righty, but it runs away to the outer half. His curveball, meanwhile, does just the opposite, hovering outside before dropping in over the last several feet. It doesn't simply fall off the table - it falls off the table while moving a good horizontal 4-8 inches. So you can see why this pitch is so difficult for hitters to square up.
Nothing groundbreaking, but still, all kinds of fun stuff. I can hardly remember what it felt like to be a baseball fan before PITCHf/x. It must've been terrible.

Can you pull his season FB and CU StS% rates?
by Jeff Sullivan on Jun 9, 2008 12:07 AM PDT up reply actions
Yep
Curve: 12.5% (that’s higher than I thought)
Fast: 7.5%
We only have a limited amount of data since PITCHf/x wasn't available everywhere last year
but based on what we have:
Curve: 20.2%
Fast: 6.0%

Is it the placement?
Maybe I’m wrong but it seems to be right over the middle of the plate pretty often.

I am loving these posts.
I wouldn’t know how to interpret PITCHf/x data if it was sitting on my face, but y’all are doing a fantastic job of making the information accessible to the likes of me. I love the pitch in flight graphs.

Absolutely
This stuff blows my mind, but it’s fun to look at the graphs and see the raw data put in an easy to digest format. Thank you guys. Also, the in flight graphs are super awesome. MORE MORE

Do you use the initial velocity and acceleration to calculate the pitch trajectory?
If so, how do you account for the effect of spin?
Yes I do
as for spin, I don’t – I’m just going with the kinematics (as suggested by Alan Nathan).
by Jeff Sullivan on Jun 9, 2008 7:50 AM PDT up reply actions
Jeff..
You said that pitch f/x picks up the ball 50 feet from home plate. So is the release point data we get on gameday actually ten feet out of the pitchers hand?
If so.. Bedard might not have a higher release point with his curve (or nearly as drastic),
More like five feet out of the pitcher's hand
it’s not this drastic, but it is still real. A matter of a few inches.

Has he just abandoned his little cutter experiment or do you think the cutters are being lumped in with the actual fastballs?

I'm so excited for the coming five-inning games the Mariners will play
How are you supposed to win if you’re losing going to the sixth and have to face
6th – Josh Fields
7th – Stephen Strasburg
8th – Brandon Morrow
9th – JJ Putz
In fact, why don't we just move Felix into the pen?

Oh shit, FOUR inning games!
That’s perfect for Wash!
Why don't we just start Felix everyday

Screw starting pitching. We should trade for thirteen dominant closers
by Last Fan Of Jose Lopez on Jun 9, 2008 9:08 AM PDT up reply actions
Ten and we'll have Silva start every game
Felix and Bedard can take the third and fourth, respectively.
On an unrelated note, I can't find any mention of Strasburg's name in the 2005 or 2006 drafts
How on earth did he go completely undrafted out of HS?
He was also only used as RP when he showed up at SD
which says something about how he was thought of coming in.
I thought that a lot of flamethrowing HS kids come in to close as FR in college?
IIRC that’s how Cal used Morrow as well
FR 19G, 5S
SO 10G, 5S
JR 14G, 14S
I think his velocity jumped like 5 mph last year

Because SDSU only had one home series after we discovered Strasburg
and SDSU used an indecipherable three/four man rotation in which Strasburg pitched random games, so we never know when he’d be on the hill

That's a little disconcerting

That means he was tossing what 92-94 in HS?
That’s still nothing to scoff at.
I'm just a little wary of sudden velocity increases
it’s not a guaranteed injury, but it’s a bit of a warning flag.
by Jeff Sullivan on Jun 9, 2008 10:01 AM PDT up reply actions
Morrow had similar increases
I believe he was a low 90’s pitcher his freshman year and and a horrible soph season partly because he couldn’t control his newly found 99mph heat
Definitely, but I'd be much more worried about a sudden velocity increase later in his career
like at the age 22-23 seasons.
If, as Graham said, he was fat coming out of HS (I’m trying to find some evidence of this), then a huge velocity jump could jsut be the result of his getting into a college strength/conditioning program and getting into shape.
Either that or HGH steroids.

Anecdotal evidence
"The plate looked really close. It looked like I could just reach out and set it (the baseball) in the catcher’s glove," said Strasburg, who started his San Diego State career as a closer but became a starter after shedding 30 pounds and adding some zip to his fastball.While he has gained velocity, he has lost none of the control that made him an effective closer.
He should be okay. It’s just something to keep an eye on.
by Jeff Sullivan on Jun 9, 2008 10:06 AM PDT up reply actions
Interesting
He’s listed at 6-4, 220 right now, which seems like a solid weight for that size, but if he came in at 6-4, 250, losing that excess weight/turning some fat into muscle, along with natural maturity would be a pretty obvious/easy way to gain some zip on that fastball

Fat kids that become not fat ...
Usually grow a little. Fat at 6feet tall and not fat at 6’4 might just be young body developing
At least he started out as a closer so he had less work on his arm when his fastball velo jumped

Strasburg converted from RP to SP?
Surely that means we can do the same with Fields, right?
by Last Fan Of Jose Lopez on Jun 9, 2008 9:46 AM PDT up reply actions
By Fields, you meant Morrow, right?
Grrrrr…..
runs away crying
It might be interesting to investigate other pitchers with regard to the curve vs. fastball slot
and see who else considerably changes their release point height with regard to pitch. It could be that the arm-slot difference for a lot of hitters, while noticeable, doesn’t make up for the fact that Bedard’s curve is damn near impossible to hit squarely.
I’d assume that guys with true 12-6’s or even very good curveballs who don’t have the large arm-slot difference would throw fastballs that tailed much less than Bedard’s (since they’d also be throwing from a higher/more vertical arm slot), which looks like it’s cutting ~six inches though the hitting zone. The one I’d be really interested in would be Lincecum, now that I think about it, btw.
New images
I’ve done my best to separate the cutter from the fastball. Note that I’ve also traced back to 55 feet away from home plate, instead of 50 (which should give us a better idea of the release point).
Ignore the horizontal distance going from -5 to 45, by the way
-5 = 55 feet away, 45 = 5 feet away, end = home plate.
by Jeff Sullivan on Jun 9, 2008 9:30 AM PDT up reply actions
Bedard started using the curve a lot more last year right?
Any chance (while its still a great pitch) part of his success last year was his featuring the curve for the first time. This season batters are laying off the pitch a little more having seen it so much last year. ?
I don't know what Bedard was throwing in '06 and before but I can't imagine he only just started using a curve last season
by Jeff Sullivan on Jun 9, 2008 10:06 AM PDT up reply actions
I watched some of his '06 starts
As far as I can tell he tweaked the curve delivery between ‘06 and ‘07 to better match up with the FB
by Graham MacAree on Jun 9, 2008 10:09 AM PDT up reply actions
according to fangraphs
he went from 22% curve in 06 to 34% in 07. Thats a pretty big increase
Jeff, how are final locations calculated?
Is it just an average of all the pitches of (x) type that he’s thrown over whatever sample size you’re using?
Yeah, it's just the average for all pitches he threw yesterday
Matthew could probably help you out if you want full season data.
by Jeff Sullivan on Jun 9, 2008 9:57 AM PDT up reply actions
Oh, was just wondering in response to Matthew wanting him to not throw the ball right down the pipe =p
but since it’s an average, I’d hope that the end location winds up somewhere near the middle of the plate
