yes, late break is a horrible misnomer. We could use full pitch flight break, or only early break, in the numbers but the context of "tunnel point to plate" make sense. Otherwise it's virtually arbitrary. Just get some slice of how the pitch trajectory and/or magnus force are making the ball go from one place to another, it doesn't really matter which slice you take.

that may be a bit of an over-reduction, but, yes. That is a big part of public facing baseball analysis, it's not just about new discovery but clearly documenting and demystifying.

that's a tip of the iceberg question. The short answer is yes. The full non-answer is something like: how do these elements make it harder for hitters to adjust; can you use these as markers for development needs/role routing based on things like "this guy can't get thru the order twice despite good stuff since he can't do X Y and Z" where X Y Z are something about his sequencing/command profile.

we like <span class="statdef"><a href="http://www.baseballprospectus.com/glossary/index.php?search=DRA" onmouseover="doTooltip(event, jpfl_getStat('DRA'))" onmouseout="hideTip()">DRA</span></a>, naturally. I think some articles will coveron that in the future, bu the main idea here is to describe and publish. As we improve our stat pages (seriously beta is around the corner, any day now) we'll make it easier for people to explore these questions themselves. As far as the teams go, yes. They do. The concept isn't new, in coaching, and it certainly has been a focus of a few in analytics-driven player development and acquisition.

great points! 1. off the top of my head, it's almost as fast (# of pitches) as it is for catchers. So a couple weeks of games is a reasonable rule of thumb, but we should dig out the proper values 2. we'll have more on that this week 3. looks like harder throwers/nastier breakers fare poorer, even though pitch type is a factor the specifics (movement speed etc) are not 4. they really create their own special pool, don't they? Especially since we're being specific to pitch type. In general, they're hard to frame 5. me too. That's why we have more stuff in the pipeline, some of which builds on the tunnel/sequence data we just published today 6. stat acronyms will be the death of me

solely relying on the assumption that 'glove is target' is one thing, making the assumption that a 'more catchable pitch' is another. We've done the latter, while commandfx relies on the former. There is much more to command than this aspect, for certain. For example, can you put your curveball back-to-back in the zone as a drop-in followed by out of the zone in the dirt?

We'll try and provide good answers to these questions in a few weeks. The pitcher has more control than the catcher, but catchers can really stand out over time since they appear in so many more games.

pitch calling etc tends to impact value less than framing does. But, yes, it is possible Scioscia had a strong preference for a guy's game calling. That said, three different NL AGMs told me, when researching game calling for ESPN, that teams will simply call games from the bench if they don't like how a guy handles pitchers.

It's interesting how _not_dropping his glove helped him. Some guys (<span class="playerdef"><a href="http://www.baseballprospectus.com/card/card.php?id=45447">Russell Martin</a></span>, I believe, is one) like to keep that glove down so there's no target to "miss". But I suspect that requires better pitch reading skills etc....much to think about here. Great work, Dustin!

Cooper Johnson was my favorite. Butt on the ground like Lucroy, stays very still, even when catching cross-body. Times I heard on his first throw were 1.7 and 1.8 fwiw.

excellent questions. Framing might get easier as you move up, and so far it appears the promotion penalty is pretty light (.01 csaa is about 1 win of value, and the penalty I'm looking at is about .002 ... tentatively ... from AAA to MLB). We'll have a follow-up on those things in a couple weeks as we suss these things out and get it into FRAA/WARP/PECOTA

Caveat to consider: the way framing is translated into runs is 'aware' of the fact that a called strike expands the zone/leads to weaker balls in play later in the AB. It may be challenging to further isolate an effect beyond this, although it is possible. So far I've thought of - look at first pitch swings - see of good framers have better LWTS (outcomes) than bad framers beyond what would be predicted by the count and other factors

great question, we haven't deeply explored those secondary outcomes yet. We've got a growing list. Including blowouts, extra innings, position players, framer impact on non-takes (more fat pitches? from Neil Weinberg), veteran status impact, familiarity with umpire impact ... and more. BTW, if anyone has specific questions about the code, speak up. We'll publish it when it's final (after this feedback round we've initiated here), but I'm happy to share relevant parts now for the curious.

Using raw CSAA (per frame chance) our top five are J. Molina .028 J. Lucroy .022 C. Vazquez .021 C. Stewart .021 R. Rivera .020 Yadi checks in at .013, McCann .011. Scioscia, btw, checks in at a robust .017 in the pre-golden era of framing _and_ at the tail end of his career. Very impressive. BTW, for a quick rule of thumb, each .01 of CSAA per chance roughly translates to a single Win Above Average over the course of a full season.

I would not consider a splitter a fastball. It's a changeup, so I'm curious how your results differ if you make that adjustment (and I can feed you some data on which cutters are used as fastballs, vs which are used as sliders ... you know where to find me :) )

it's not likely they'll do this again in 2014. Game 6 is not an option but there may be a tiny small slight eeny itty bit of a sliver of a chance that G1 of the WS can have it. Highly unlikely. Did I mention that it isn't likely to occur?

My ears are burning. I realize I'm too risk averse to be a GM or scouting director but if you give _me_ a chance to get immediate and lasting value with 3 tiers of projection (OBA, game calling, pitch blocking), I'm taking it. Castro, not an issue. Take the player that meets the cost/impact/risk assessments the best. Zunino fits the bill. Development costs: almost nil with Zunino, outside of having Buck around to mentor him (PLEASE just focus on game calling there). Catchers often cost a great deal (of time) to develop. Also, developing receiving skills etc. often detracts from development of hitting skills which gives Zunino some more hope to fulfill some of the projection with the bat and eye that other catchers may not. As much as I love Wacha, Correa, Buxton ... even Gausman. Just too easy to take a guy like Zunino. Not for you, fine. But this didn't come flying out of my ass.

r sq. would be about .72 or something, so that's a better measure of variance explained--which is still awesome. But, yes, we need to re-run that analysis and see how well it holds up. We'll actually go ahead and publish 'projections' when we post the full set of zone contour images.

simple 3-2-1 weighted projections correlated something like .85 to next season performance (we'll re-run that, it's been a while) so the skill is stable (Dan did some more analysis on that, maybe he chime in--in short we haven't found the aging curve yet). the wowy analysis attempts to tease apart the pitcher and catchers, we have a fair amount of confidence in that particular aspect but it's something that we intend to tune and explore in future versions I think we have a lot more to learn about framing, but we're happy with the direction we're moving with this model (warts and all) Thanks for the thoughtful feedback, keep it coming!

Thanks! Yes, we will be updating in-season. We'll use the 2013 model and hold off on xy corrections until we have enough to establish a reliable version for each. We'll also have to deal with new pitcher/umpire corrections, so the #s will be squishy day-to-day. And, yes, the block data is the same RPM approach with fewer factors (we ignore count and season). Thanks for the insight on the WARP integration, much appreciated.

Comment rating: -

basically what ever credit we give (or blame we assign) to the catcher is taken away from the pitcher and defense. How that's shared is influenced by, in this example, Glavine's ownership likely being more than the norm. We shall see. But, yes, you have to take it way from someone else if we add it to the catcher, and the first victim will be the dudes on the bump. Also, if a pitcher had bad framers working for him, whether or not he was a good one, he'll get some credit back.

 
Harry Pavlidis
(25252)
Comment rating: -

this is a topic of debate. I was on the "use a constant value" side until we realized the importance of resizing the zone by count. So the model is context-aware at it's core. Our decision (and we could be wrong) was to retain that context for the run values. If you look at our sortables, you can see the .14 based values for comparison. The field is "FR_RUNS_ADDED_BY_CALL" which reminds me I need to update the glossary before Ben notices I haven't.

yes, I actually provide the same data to both Brooks and BP. We intend to use it for projections, and other things, in short order. One possible example would be accounting for a less regressable GB rate for a guy who just added a sinker, or started throwing it more often. That would trickle thru in a variety of ways.

what we have planned is analysis of roughly six metrics for hitting and pitching -- basically the five roto categories (we figure that's a common use for PECOTA, planning a draft or dynasty roster) and wOBA for an all-in-one metric. We're calculating things like mean average error (weighted and unweighted), RMSE, correlation on common projections to compare the systems. We have some other ideas already, but if folks have things they'd like to see us measure/compare we're happy to hear your suggestions.

a very important question. It's a layer or two deeper than the current stage, but we're headed there. The thing with offspeed stuff is every grip is different. You can see splitters fade (Fister) or changeups tumble (Cueto). Rich Harden threw (or throws) a circle-change that acts like a slider. People think it's his splitter sometimes, too. So my philosophy is (a) try and identify changeup vs splitter grips as much as possible; but (b) group them together for high level analysis
