E-Jax ERA masking questionable performance
Edwin Jackson pitched what would likely be considered a gem by the general sports media, giving up only 1 run on the road to Seattle. However E-Jax is in some ways less dominating than he was late last year. If the Rays can sell high on the 24-year old during the off season for reasonable return, I think they absolutely should do so.
To confirm Jackson's skill set has not been as solid as his ERA, I turned to the analysis of Ron Shandler's Baseball HQ website. While Shandler is most known for his expertise in Fantasy Baseball (creator of Tout Wars and multiple time champion), his research qualifies him as a new generation Bill James. One of the first to break down skills into component analysis, Shandler's research can be turned to with confidence.
Whereas Baseball Prospectus has PERA, Shandler has XERA (Expected ERA). XERA is based on proprietary formula which takes into account individual peripheral analysis (K/9, BB/9, K/BB) while also considering GB/LD/F percentages, BABIP, and strand rate (how many runners score after reaching base). When ERA and XERA significantly diverge, a regression becomes increasingly likely.
Coming into Sunday, Jackson has been averaging a mediocre 5.2 K/9, while walking 3.9 per 9. This yields a rather dismal K/BB ratio of about 1.3. More troubling is Jackson's K/BB ratio for the last 31 days is down to 1.0, with his K/9 down to 4.5. His strand rate for the season is 74% (a good rule of thumb is to expect 70-72%), but over the last 2 games the strand rate is at an unrealistically elevated 80%.
Jackson's expected ERA (XERA) has risen to 5.50 for the season, nearly 1.3 runs per 9 more than his actual ERA. For the last 31 days, his XERA is even worse at 6.22. A correction is due.

Get a good prospect or two in return for him. He’s obviously playing over his head and we need to make room anyway.

Shandler
is a very interesting read. I know he was contracted by the Cardinals as an analyst a few years ago. Not sure if he is still with them or not, but most consider him to be right up with Bill James in terms of knowledge and innovation. A lot of the current regression type fomulae applied to K/9 vs BB/9 was aped from Shandler, who was talking about it over a decade ago as far more reliable than current ERA for predicting future ERA.
RJ, who do you use for defensive analysis? I want to read a good source for quantifying the difference people like Barty and Pena make in the field.

zone ratings are the best publicly available right now
Justin has good explanations of converting zone ratings into runs—check out the player value series on his sidebar. You could also read Dave Pinto’s work on PMR over at Baseball Musings, which goes an extra step, like UZR.

Whatever happened with James' Defensive Win Shares Method?
Did he scrap it, or does no one else value it?
by rglass44 on Aug 12, 2008 10:30 AM EDT up reply actions 0 recs
it's still used whenever you see win shares
but there’s no reason to use a non-play-by-play stat when there are plenty of play-by-play stats available (i.e. zone-based metrics). that’s also why BPro’s fielding stats are hooey.

i'll also add
that there is definitely some merit to James’ top down approach. fielders position themselves relative to other fielders—you don’t usually shift a shortstop and not the third baseman and second baseman, too. it’s just really hard to take this approach with the data currently available, and it doesn’t make a huge difference. losing this top-down approach is insignificant compared to gaining play-by-play data.

I didn't realize Edwin Jackson has peaked
I just love how many folks here simply use historical data to judge Edwin Jackson. Christ if that is what you do to every young player then you wouldn’t have any left. Well besides Evan Longoria, but BJ Upton certainly would not be here. Hell compare Kazmir and Jackson. Clearly Kazmir is better than Jackson now and probably always will be. But his reputation is far better than his actual performance (which is pretty crappy lately to say the least). Whys that? Because we all know he is going to get better and better. Well why doesn’t Jackson get the same benefit of the doubt. In fact Jackson should get more considering how raw he is. I hate this obvious witch hunt and double standard.
I’m all for trading any player if we get the proper return. But if you are just going to ask for a return based upon what hes done the past couple years then you are clearly selling low, very low.

If someone offers you the value of a #2 starter for Jackson then we most certainly take it. Maybe even a 3, but that is only because of organizational depth.

Other than not allowing a ton of runs
What have you seen from Edwin Jackson that makes you think he’s turned a corner, or that he’ll continue to improve?
The point of the original post, however, was that even if Jackson continues to improve, he could STILL end up with a worse ERA than what he has right now because his ERA is flukey good at the moment.

What haven't you seen?
He is obviously a better pitcher over the last year and a half than he was before. Why would he not continue to improve? He is young and has good stuff. XERA’s numbers are obviously inflated as BERA has him with an ERA almost a full run lower.
There is such a double standard with regards to Jackson. He is getting out of jams now so people call him “lucky”. If he had a below average strand rate then people would say he has no composure and that he melts down when under pressure. Either way he gets no credit.
Plus wouldn’t better pitchers have better strand rates. I don’t get why this is considered luck.

Actually we would say he’s bound to regress to the mean and that he’s been unlucky.

OK
Let’s just theoretically say that the improvement is for real, and that you think he’ll continue to improve. For whatever reason, his XERA is way off, and his real performance level is closer to his BERA (although it’s not like his strikeout rate is improving in big spots, which is how he could control having a higher strand rate). Even as such, I’d argue that this is the highest Jackson’s value is ever going to get in a Rays uniform, and that he should still be traded, unless you think he has higher upside than Kazmir, Shields, Garza or Price.
1) The four guys I just mentioned are all under team control for the next 5 years. At most, there will be two open spots in the rotation next year, and probably only one. If nobody gets traded, someone needs to move to the bullpen. I’m not sure that either Jackson or Sonnanstine is a huge marginal improvement over what we have in the bullpen right now. Thus, for at least one of them, their value would be MUCH greater if they’re traded to another team than if they stay here as a reliever.
2) Jackson hits arbitration this year. If he continues to perform well, he will get expensive pretty quickly. It’s a good problem to have, but it does mean that his relative contribution is lower than someone whose salary won’t start increasing for a few years.
3) Jackson is out of options, and thus we can’t just stash him away until someone gets hurt. This decreases his value with us long-term, since those 5 guys are all under control, plus there are still guys like Davis, Niemann and Hellickson coming up in the next year or two.
4) Jackson has three years left with the team. While that’s great for most teams, it’s less than any of our other starting candidates.
5) We have some huge holes in our team and in our system. As of right now, Gabe Gross is #1 on our RF depth chart next season (Hinske and Rocco are FAs), and there’s really nobody with great promise coming up in the system. Our system also has black holes in the outfield in general, and at 1B and 2B. Getting a guy at any of these positions would be of more use to us than a comparable pitcher, since we have so much pitching anyway. It makes sense to trade for a weakness from a position of strength.
6) Because Jackson has a higher ceiling than Sonnanstine, was a better prospect than Sonnanstine, and has performed better than Sonnanstine this year, I believe that his trade value is higher than Sonnanstine’s for most teams. Things that make him less valuable to this team, such as his increasing salary and lack of options, shouldn’t play nearly as big of a factor with most other teams, where he would be a clear #3 starter rather than a marginal #5.
7) Despite putting up a better ERA and clearly having better stuff, there are a lot of reasons to believe that Sonnanstine might actually be the better pitcher long-term. However, even if he’s not, it should be relatively obvious that he’s still one of the better #5 starters in the league, and that he could be a solid swingman once the rotation is otherwise full.
For these reasons, even if Jackson isn’t due for a regression, it makes the most sense to trade Jackson this offseason. I wouldn’t be disappointed if Sonnanstine is the one who gets traded, but I do think that one of them should get traded, and I will be disappointed if we head into next season and Jackson, Sonny and Niemann are all fighting for the #5 spot while we have other positions that still need to be filled.

You make plenty of good points
Jackson and Sonny are in the same boat. Their future with the Rays most likely isn’t going to be as a starting pitcher. That being said the best value they give the team in the offseason is as trade bait. But it is very important that we properly value them since Sonny is an above average starter and Jackson has a serious chance at being a strong #2. We need to find trade partners that have that sentiment.

what’s the cut-off on that? all of 2007 and 2008, versus pre-2007? that i’d agree with.
it’s the folks who think he’s improved from 2007 to 2008 that are misguided.

Regarding Jackson people need to look at the entire picture
He was a project when we got him and he is still being developed. Remember he was a converted outfielder who hit the big leagues in no time. The guy was and is raw as hell. Sure there is a chance he may not improve. There is a change he may regress and there is a chance he may become a strong #2. Take Sonny for example, and there is nowhere near that much of a difference in terms of what we expect. What we see now is what we are going to basically get forever. A very solid above average starting pitcher. Sonny is FAR more refined and experience than Jackson. It simply just isn’t fair to compare the two.
Clearly some people here are not as high on Jackson as others. But that is the entire point. With Jackson we have to project into the future in order to find his value. Where he is at currently is only a small part of the picture.

i put “new” in there because you mentioned he was still raw. my point was that he’s had seven years of pitching—I question to what degree he’s still raw. he’s not new to pitching at this point.
he certainly has room to improve. but as someone else pointed out, he could still improve and not see his ERA get any better, as he’s been a bit lucky this year. his current skills are as an approximately 5.00 ERA pitcher.

I don't think he's peaked
Actually I don’t think he is anywhere near his potential. But then Billy Beane never approached his field potential in an entire career.
I’m looking at thing from the perspective that at least one of our arms has to be traded for a bat. With Price almost here, and Hellickson not far behind, either Sonny or Jax needs to go. (Unless they want to roll the dice by trading Garza for multiple high prospects)

How long will this continue?
It doesn’t matter if Jackson has a good start or a bad start, all of the know-it-alls see it as an opportunity to slam him. I know it pains many that his long called for regression hasn’t occurred yet. But here we are, 3/4 of the way through the season, and he’s still defying the skeptics.
This season has just continued a trend that began last summer. He has been a very steady performer, much more consistant than given credit for, over his last 35 starts. That’s quite a bit larger sample size than the last 31 days that the sky-is-falling op often uses.
As far as selling high, you run just as much risk of selling too low. By all accounts, Edwin is a hard worker with immense potential. Odds are he will come back next year with more confidence and polish, and will definitely have more experience. Who really wants to trade a durable 24 year old pitcher who has already shown the ability to get big league hitters out even though he is still rough around the edges? Call me a dimwit if you must, but I sure don’t.

You're assuming regression will take place within the arbitrary timeline of a season.
Nothing you stated (confidence, polish) is making him a better pitcher. Limiting his walks would, and he’s doing a worse job of that this year than he has for his career.

what's interesting
is that these exact same stats and know-it-alls were claiming exactly the opposite last year—Jackson (and Sonny and Howell, etc) were much BETTER pitchers than their ERAs showed. whoila, they’re all posting better ERAs. Jackson’s ERA has gone too far, however. Sonny’s hasn’t gone down quite enough. Howell’s just about right, maybe slightly low.
you can expand the list to non-Rays, too. if you accept the premise to explain 90% fo the players, then you better have a good reason why Jackson is an exception.

by stpetelawyer on Aug 12, 2008 3:35 PM EDT up reply actions 0 recs
Intuitively,
I can understand a pitcher performing worse with runners on base, since they’re pitching from the stretch, fielders are out of position, or whatever (I think the effect has the potential to be very overstated, but it is possible).
But intuitively it doesn’t make much sense for a pitcher to pitch consistently better with runners on base. More likely, it’s a sample size fluke, and will regress to the mean.

The only reason I was saying Jack Morris is because he claimed he would do this, pitching to contact except where he got into a bind (and that if his team was way ahead, he wouldn’t even try to prevent runs), and then has since used it to justify why he should be in the Hall of Fame even though he was almost never dominant in his career.

There is something to be said for the reliable innings-eater though....
I think that is Edwin’s floor at this point. If you can get good return on him then trading him for a younger corner OF would be a good idea (trading from depth to fill a weakness). I wouldn’t trade a 24 YO PROVEN major league starter because his peripherals call for regression. At some point, it seems someone will have to be moved, but to force a deal seems to run counter to the way the FO does things. Maybe we could do a Lastings Milledge for Edwin deal before Jim Bowdin gets fired. That would probably take a lot of heat off of BJ from the local sports media (read stupid talk radio idiots).

Just watching him pitch....
COmbined with all of the statistical analysis that has been mentioned, it is clear to can not succeed long term unless his improves immensely. Obviously his K:BB ratio is bad, but even when he throws strikes, he isnt consistent within the strike zone. That is one of the reasons he is so inconsistent, combine walking people and throwing bad strikes, and poor results are sure to follow.
Regardless, I have been happy with the RESULTS from EJ this year. Personally, I think he would be awful out of the pen. Low K rates and high BB rates are just as disastrous coming out of the pen. I’ve been a big propenent of selling high on EJ this offseason. There will be an idiot GM that sees a young pitcher with 3 (?) years of team control left that is a #3/4. That can usually get some nice prospects in return. And in case people havent noticed, there arent too many hitting prospects in the Rays org right now.

Rather than banking on their idiocy
What you hope is that someone sees the future potential and starts dreaming of him as a #1. It’s reasonable to do so. I know if we traded him, there would be a lot of angst. He does have nasty stuff, even if he has yet to learn to control it.

and keeps his ERA under 4.25, I think we could sell him to an NL team as a #3 starter with 3 years of team control and even more potential.

What a surprise, same old Jackson hate, same old BAD arguments
Scott Kazmir has poor GB:FB rates, very average K:BB rates, and his WHIP for most his career has been slightly below average. So by this genius formula of determining whether EVERY pitcher is good or bad, says that Kazmir is a fringe MLer. YAWN
Fact is, JAckson’s stuff is good enough that, like Kazmir, he can give up BBs and flyballs that most cant because the opposing hitters arent getting the same wood on the ball that you assume when you use those stats. Thats the problem. You are assuming. Assuming Kazmir and Jackson are equal to the rest of the league, and treating them like that. Its wrong. They arent. Jackson gives up a lot of lazy fly balls. He gives up a lot of BBs, and not many hits, and those runs dont score lke hey would against the average ML pitcher. I mean you cant ONLY use thsoe stats, as good as they are at showing gthings that pitchers are doing, and completely ignore whats actually happening in the game
One quality Kazmir and Jackson share that is ignored, is they both try too hard to hit spots and both have the ability to miss within the strikezone and get guys out. They both do this, yet when Jackson does it he is called a bad pitcher

Kaz’s K:BB over the past three years has ranged between 2.5:1 to 3:1 - That’s quite good, not average. His WHIP over the past three years is about 1.30 - definitely better than average, especially for a starter, and especially considering the poor defenses before 2008. By “this genius formula”, Kazmir’s expected ERAs (xFIP) for the past three years have been 3.68, 3.91, and 3.93, certainly not “fringe”. Jackson’s xFIPs over the past three seasons are 5.50, 5.02, and 5.15.
Feel free to disagree about talent, stuff, and potential, but please don’t make shit up.

Pitchers can control three main things:
1) Striking batters out
2) Walking batters
3) Getting ground balls
If you are average at all three, you’re probably a 3/4 starter. Kazmir is fantastic at #1, poor at #2, and average at #3 (although below average this year). However, #1 is the most important, and since Kaz is good at that, he’s a very good pitcher. If he can improve at #2 and/or #3, he can be one of the best pitchers in the game.
Edwin Jackson is below average at #1 and #2, and average at #3. His average ability to induce grounders, combined with below-average but not AWFUL) strikeout and walk rates, suggest that his ERA should be around 5.00 or 5.50. Any deviation from this (read: his current ERA) is almost certainly due to good luck.
Jackson has good stuff and thus has the potential to improve. But he’s still quite far away and is probably somewhere around the 8th or 9th best starter in the organization at the moment.

“PItchers can control 3 main things

LOL yea in the excel spreadsheet world of baseball, I guess thats true. So you mean there is no difference between how hard a flyball is hit off Sonny compared to Kazmir? You mean tehres no difference how hard and how well a hihtter hits off of a pitcher? You mean LOL. This is such an incomplete way of judging a piutcher it makes me laugh so hard everytime I hear these crazy exoplanations.

You can see how hard balls are hit off of Kazmir and Sonnanstine.
This year, Kazmir has allowed line drives on 21% of the balls in play. Sonnanstine has allowed line drives on 17.8% of the balls in play.
But I guess that’s just the spreadsheet world of baseball (which may or may not have anything to do with actual baseball, where the spreadsheet gets it mythical “statistics” from).
Do you have any counter-argument to what I’ve said, or is your counterargument simply “you mean LOL”?

there are definitely differences, and I would say the current state of sabermetrics ignores these differences too much
but an amazing amount of what makes a successful pitcher is included in those three things.
my wild ass guess is that given a pitcher’s skill in those three factors, his skill in BABIP and HR/FB adjusts his ERA a quarter of a run higher or lower.

Example:
Jake Westbrook, from 2004-2006, was INCREDIBLY consistent:
2004: 215 IP, 4.85 K/9, 2.55 BB/9, 0.79 HR/9 (14.0% HR/FB), .272 BABIP, 72.4% LOB
2005: 210 IP, 5.09 K/9, 2.40 BB/9, 0.81 HR/9 (19.0% HR/FB), .287 BABIP, 62.9% LOB
2006: 211 IP, 4.65 K/9, 2.35 BB/9, 0.64 HR/9 (10.1% HR/FB), .322 BABIP, 70.2% LOB
His ERAs were 3.38, 4.49, and 4.17 from 2004-2006, respectively. Westbrook was the EXACT same pitcher every season, but his ERA fluctuated over one full run due to BABIP, the amount of fly balls that left the park, and left-on-base percentage in each season.
I think that a pitcher’s ERA can fluctuate a lot due to factors that are out of his control, thus making it difficult to assess his “True Ability” by ERA alone.

and to clarify, i mean that...
a pitcher’s true BABIP skill and true HR/FB skill (they do have skills in these areas, it’s just that they don’t vary from pitcher to pitcher as much as with K, BB, and GB rates) will cause a pitchers TRUE ERA estimate to vary by a quarter of a run higher or lower. so you could have two pitchers who show the exact same skills in K, BB, and GB rates, but you would expect one to have a 3.50 ERA and one to have a 4.00 ERA if they had vary different stuff which caused more solid or less solid contact. that’s the extreme, though, and it’s extremely overrated.

Agreed.
I think there was a THT article which summed up the “skill” of BABIP nicely: basically, fly ball pitchers and pitchers with a lot of movement on their fastball tend to have the “skill” of reducing hits on balls in play somewhat (although, like you said, it’s extremely overrated). So it’s not so much a “skill” that Carlos Zambrano can keep his BABIP low, but rather Zambrano possesses a style which tends to reduce BABIP, if that makes sense.

Jackson
E-JAX is doing just fine the bull-pen isn’t giving him any breaks just like evrytime Sheilds looses a 2-1 game i die a little. E-JAX should become the close in my opinion if he steps up his fastball to his old 97MPH but with some control.Now I have no clue about SONI.

I don't think you can use both Jackson and Kazmir
to make your point. I am not sure what an average K/BB rate is, but Kazmir’s is considerably better than Jackson’s. This year it is 2.59. Last year it was 2.68, and that was mostly due to a poor first half when he was walking a lot more batters. His great second half was fueled at least partly by a dramatic improvement on that score.
And in 2006, when he seemed to break through before getting hurt, the ratio was 3.13, which I think is pretty good. That was the year he improved his BB rate by almost a full walk per 9 while maintaining his high K rate.
With Jackson, we are not seeing anything like those kinds of ratios or development. His K/BB rate this year is 1.31 and last year it was 1.45 as his K rate is falling faster than his BB rate.
You may be right that Jackson is improving in other ways. Jackson’s hit rate is down to about one per inning this year. For his career it has been almost 10/9. (Kazmir has never had a season of 9/9, his average being around 8/9.)
He is still giving up more home runs than Scott as well, 1/8 IP vs. 1/10 IP. He does seem less prone to collapsing early in the game. It remains to be seen if that is a skill he has or a matter of luck.
In any case, I am not arguing that Jackson has not improved, will not continue to improve (if he has), or does not have some attributes the stats are missing. I simply do not think any effort to associate him with Kazmir to make a point is valid.

He's not Kaz
He’s no Kaz, but I see a potential closer in him if he gets a little confidence.

Assuming Price joins the rotation next season and there is only one spot available, which one of the following five guys would you choose to not have in the rotation and trade? I’ve listed their Fielding Independent ERA for the past two seasons.
1. 3.86 – 3.75
2. 4.18 – 3.98
3. 4.90 – 4.87
4. 4.26 – 3.50
5. 3.45 – 3.50
I’d trade #3 myself as his best FIP is something like 3/4ths of a run higher than any of the other guys worst FIP. #3 conveniently happens to be Edwin Jackson.
Simply because of his age (24), his team control (3 years), and skill set (#4 starter) I’d imagine there’d be plenty of suitors from around baseball. His upside may have been a #1 starter at some point, but he now has over 400 ML innings under his belt and he’s spent the past three years regressing in K/9, regressing in BB/9, regressing in GB %, and masking that with a better than league average LOB %, an artificially low BABIP, and an improving team defense. I could buy into the developing ace theory if his peripherals were actually improving (meaning his command and control were improving) as his stuff is clearly great, but they haven’t improved.
I’d cash in my chips where he is now as it’s pretty clear that rotation spots will be at a premium from here on out and if he regresses to his expected almost 5.00 ERA next season, he won’t be worth much of anything on the trade market.

If you can see this, won't MLB GMs or scouts?
by rglass44 on Aug 18, 2008 6:14 PM EDT up reply actions 0 recs
not only did the Twins just claim Washburn off waivers, the Mariners pulled him back
We’re talking about a pitcher with 5.00 ERA talent and $13MM left to be paid to him through next year. MLB teams do dumb stuff all the time.
