Dave Cameron FanGraphs Chat: 10/1/14
| 12:07 |
: Alright, so, apologies for the delay.
|
| 12:08 |
: In my defense, I’m still exhausted from last night. Maybe that’s no defense at all.
|
| 12:08 |
: So get mad about the late start, but we’ll go long to make up for it, assuming I don’t pass out first.
|
| 12:10 |
: Chat will kick off in 5-10 minutes, once I get a few more things squared away.
|
| 12:15 |
: Alright, let’s get this thing started.
|
| 12:15 |
Brewers’ brass are believing they had too many swing for the fences type hitters in the lineup which was the demise of their offense as the season progressed. Your assessment of that perspective?

|
| 12:15 |
: It’s bunk.
|
| 12:15 |
: They dramatically overachieved early on in the season, then regressed to the mean.
|
| 12:16 |
: If they want to win more games, they need better players, and they shouldn’t care too much whether their good players strkeout or not.
|
| 12:16 |
What gives? Sullivan is on time this week and you’re late? It’s like bizarro FanGraphs! |
| 12:16 |
: Weird combination of events: I did a radio interview in Toronto at 11:40, which is when I usually launch the chat window. Then Liberty freaked out during the interview, and I spent 15 minutes trying to calm her down. Then my phone rang with a call I had to take.
|
| 12:17 |
: So, yeah. Sorry!
|
| 12:17 |
when should have Melvin hooked lester last night and why |
| 12:17 |
: After the 6th, when they took the lead, because tiring starters shouldn’t be protecting one run leads in elimination games.
|
| 12:18 |
Dave, do you stand by what you wrote about the A’s going for it this year, given all that has happened since? |
| 12:18 |
: Yep. There was no reason to think the A’s second half collapse was imminent, and all the information at the time suggested that the team was setup for a strong chance at a deep playoff run. It happens.
|
| 12:18 |
Do you see Donaldson being traded? |
| 12:18 |
: No.
|
| 12:19 |
If you could “blame” only one person for yesterdays loss, would it be Lowrie? |
| 12:19 |
: Melvin, for sticking with Lester too long.
|
| 12:19 |
Were any of the 18 bunts last night the right strategy? |
| 12:19 |
: I’ll do a quick post on this in the afternoon, but there were seven bunts last night, and I only had a problem with two of them.
|
| 12:19 |
: Bunting early is silly. Bunting in extra innings of a tie game is not silly.
|
| 12:20 |
Will Samardziza get traded? |
| 12:21 |
: I don’t see the A’s changing course and deciding to rebuild. They’re a good team that had a bad finish to the year.
|
| 12:21 |
It’s possible that the A’s would’ve done *worse* had they not traded Cespedes. There. I said it. |
| 12:21 |
: Not just possible; likely.
|
| 12:21 |
Should Ventura be left off the DS roster? |
| 12:22 |
: What, no.
|
| 12:22 |
Are there any instances in which a team has “rented” a player to another? For example, if Team A, who was struggling in July, traded a productive starter to Team B, who was in the playoff hunt, for a prospect. Maybe there’s collateral involved. Then, during the fall, Team B moved the starter back to team A. It seems like a win-win, and I’m surprised we don’t see it more often. |
| 12:22 |
: You’re not allowed to make trades based on promises of future transactions that aren’t explicitly laid out in the deals. It’s against the rules.
|
| 12:23 |
Yost getting roasted, but I think you have to disentagle the 2 parts of decision. |
| 12:24 |
: I have a piece going up at some point today on Fox that defends the Ventura decision to an extent. He’s getting way too much crap for that.
|
| 12:25 |
How much sleep did you end up getting Dave? |
| 12:25 |
: About six hours. More than I expected!
|
| 12:25 |
the trade rumors blather will have Heyward and Stanton as the biggest offseason target.. Can you definitively state neither guy is going anywhere during the coming offseason? |
| 12:26 |
: The Marlins have said definitively that they aren’t trading Stanton this winter, extension or not.
|
| 12:26 |
Most frustrating false narrative to come out of last night’s game? |
| 12:26 |
: The “should have stuck with Shields” argument is the dumbest one I’ve seen.
|
| 12:26 |
Was Liberty on the radio? |
| 12:26 |
: Very loudly. She literally followed me around the house barking at me during the interview. I finally had to go upstairs (where she’s not allowed) and close the door.
|
| 12:27 |
So if Soto doesn’t get hurt, the A’s win that game? |
| 12:27 |
: Not necessarily. Maybe Soto doesn’t get the RBI single that Norris got. Maybe they still run anyway. Maybe they don’t run and someone hits a HR instead of laying down a bunt. Who knows?
|
| 12:28 |
How bad does the Addison Russel trade look in hindsight? |
| 12:28 |
: There’s no reason to judge a decision using hindsight.
|
| 12:29 |
You see a lot of “[Team] asked permission to speak with [coach under contract with another team]” around this time of year. Is that request ever turned down? If so, why? |
| 12:29 |
: Yes, if it’s a lateral move, a lot of teams will say no. The general rule in MLB is that teams will let their people leave for a promotion, but not if its for the same title.
|
| 12:30 |
Last night’s game was one of the top 10 most entertaining games I’ve ever seen |
| 12:30 |
: Agree. Maybe top 5.
|
| 12:31 |
So the A’s were unlucky in the second half, but they were good (as opposed to being lucky) in the first half? |
| 12:31 |
: They good were and lucky in the first half, and mediocre and unlucky in the second half. Overall, they were a good team.
|
| 12:31 |
Lot of talk in the Twin Cities in support of Ozzie Guillen as the next Twins manager. Do you have a take on Ozzie as a manager? |
| 12:32 |
: You don’t want that.
|
| 12:32 |
How can the A’s improve in the offseason? |
| 12:32 |
: Upgrade the middle infield.
|
| 12:32 |
Is there a metric for “excitement” of a game? You could add the absolute value of change in WPA with each at bat, and this would show which games had the biggest swings in expectation. It’d be nice to see where last night’s game ranked in terms of excitement for post-season games. |
| 12:32 |
: Average Leverage Index works pretty well.
|
| 12:34 |
Harold Reynolds was saying that it makes less sense to bring a normal starter (e.g., Ventura) as a reliever *when there are men on base.* Any merit to this idea? |
| 12:34 |
: Fun fact: Yordano Ventura, in his only career relief appearance as a big leaguer, came in with a man on first base in the 6th inning. He dominated anyway.
|
| 12:35 |
Who (or what type of player) is the most overrated by WAR? |
| 12:35 |
: Terrible defensive catchers. So, Ryan Doumit back when he was catching.
|
| 12:35 |
Even if you wanted to “defend” Yost bringing in Ventura, weren’t there much better options than that? |
| 12:35 |
: Yes. It was not the best decision. It was not obviously a disaster either, though.
|
| 12:36 |
Gut feeling: how much of the 6 A’s called strikeouts last night was Perez’s framing versus Bill Miller? |
| 12:36 |
: Perez is not a good framer. It was Miller.
|
| 12:37 |
Who’s chatting tonight? |
| 12:37 |
: Sullivan and Swydan.
|
| 12:37 |
Thoughts on the NL WC game tonight? |
| 12:37 |
: Too much being made about the SPs, not enough about the Pirates significant offensive edge.
|
| 12:38 |
Should the Mets trade for Jay Bruce while his value is down? He seems like a good fit/likely bounce back candidate |
| 12:38 |
: The Reds probably agree, so why would they sell low?
|
| 12:38 |
whats your rationale behind your argument that Melvin kept Lester in to long |
| 12:39 |
: Basically no starting pticher should ever be allowed to face a line-up a fourth time through the order in the postseason.
|
| 12:40 |
And it follows that great defensive catchers are most underrated? |
| 12:40 |
: Correct.
|
| 12:40 |
what do you think about the KC- LAA matchup? angels rotation a concern |
| 12:40 |
: Angels are a better team, but it’s a short series, and so both teams have a chance. I’d say it’s probably 60/40 LAA, or something like that.
|
| 12:40 |
But what about coming in on one day rest with two on no outs in sudden death game? Why not go herrera/davis/holland for 4 outs each instead of 3 outs each? |
| 12:41 |
: Agree that would have been preferable. Even using Finnegan or Duffy probably better too. It was not the best choice. It just wasn’t a “WTF you moron!” kind of choice either.
|
| 12:42 |
aramis ramirez to the cubs? |
| 12:42 |
: Not unless the NL adopts the DH next year.
|
| 12:43 |
No more than trips through the lineup for Volquez tonight? (unless he’s ridiculously ‘on’?) |
| 12:43 |
: I’d limit him to 15-18 batters faced.
|
| 12:43 |
Why are there so few, but not zero, bunts against overshifts? It seems to imply they think it’s a good strategy only against a vanishingly small group of pitchers, which strikes me as absurd. Since we’re on the subject of bunts. |
| 12:43 |
: Bunting for a hit is harder than it looks.
|
| 12:44 |
Would (Castro/Baez), (Alcantara/Almora), Schwarber, CJ Edwards be enough for Stanton? |
| 12:44 |
: Not even close.
|
| 12:44 |
Geez. Are you worried about Jeff potentially dying if the game is at all like last night’s? |
| 12:45 |
: Tonight is his last chat for the week. I’m taking Friday off to hang out with my wife. We’re trying to keep ourselves from burning out.
|
| 12:45 |
Couldn’t one also argue that elite relievers are underrated by WAR? By the nature of their job, they pitch in the situations that matter most (even a strict 9th inning close still pitches in very high leverage) so even though part of their value is situational, it’s still a situation that they are put in because of their skill set. |
| 12:45 |
: Leverage is included in WAR.
|
| 12:45 |
What’s a “good” wRc+. |
| 12:45 |
: 120ish.
|
| 12:46 |
who is the biggest name to be traded this offseason? |
| 12:46 |
: Maybe Cueto.
|
| 12:46 |
David Schoeinfield wrote an article during the game entitled, ‘Ned Yost shows why he’s a terrible manager’ in regards to who was brought in to replace Shields. Based on this chat so far, that’s a bit over the top,no? |
| 12:46 |
: Yeah, I don’t agree with that at all.
|
| 12:48 |
I thought WAR was context neutral? |
| 12:48 |
: Releiver leverage is an exception, since their own talent dictates that they are used in higher leverage situations, so they “own” that leverage to a dgree.
|
| 12:48 |
: a degree, even.
|
| 12:50 |
: Think of it something like batting order for relievers: good hitters hit at the the top of the order because they’re good hitters, so they get more PAs throughout the year than bad hitters. This gets included into their WAR because they get more opportunities. Better relievers don’t necessarily get more innings, they just get more important innings, and including leverage gives them credit for that.
|
| 12:51 |
How much of an impact do you think Travis Ishikawa in PNC Park LF will have, especially when you consider than the Pirates will likely have 7 or 8 position players bat from the right side? Dude has 32.2 innings of OF experience and that’s a HUGE left field. |
| 12:51 |
: Right-handed batters don’t hit balls in the air to left field very often. Pulled balls are grounders, mostly.
|
| 12:51 |
Does war value offense and defense equally? |
| 12:52 |
: No. WAR values runs evenly, but there are far more offensive runs to be had than defensive runs in a season. The range of defensive runs in WAR was +22 (Simmons) to -25 (Kemp) this year. The range of offensive runs was something like +60 (Trout) to -35ish (I don’t remember who).
|
| 12:53 |
“Leverage is included in WAR.” Are you sure? this is what it says in the glossary, I don’t see anything about leverage: WAR = (Batting Runs + Base Running Runs + Fielding Runs + Positional Adjustment + League Adjustment + Replacement Runs) / (Runs Per Win) |
| 12:53 |
: That’s for positional players. Leverage is included in pitching WAR, but it only really matters for relievers, since SPs all have leverage indexes around 1 anyway.
|
| 12:54 |
Please explain what you mean by “more important innings” I’m no expert, but the last time I checked they tally up all of the runs at the end of the game, and runs from one inning count the same as runs from every other inning. |
| 12:54 |
| 12:55 |
I’m mad at Fangraphs for reducing my WAR from 8.0 to 7.8 after the season ended. WTF – my defense isn’t THAT bad. |
| 12:55 |
: UZR updates on Tuesday, so the final update included the last of the defensive ratings being included.
|
| 12:56 |
On Ishikawa — more to playing left than shagging fly balls. Huge LCF gap, plus requires range to cleanly field those groundballs on the run |
| 12:56 |
: Not saying Ishikawa’s defense wont’ be a factor; just see too many people concluding that RH hitters = need for good LF outfield defense.
|
| 12:56 |
What is the best barbecue joint in winston salem? |
| 12:57 |
: Depends on what you’re looking for. if you want Lexington-style pulled pork, a lot of people like Little Richards on Country Club Rd (cash only). If you want non-sauced smoked meat, Honkey Tonk Smokehouse on Jonestown is good. If you want a hybrid blend of types, Big’s is pretty good downtown.
|
| 12:58 |
: Bib’s.
|
| 12:58 |
Thanks for writing yesterday’s column “A Few Pieces of Advice for Ned Yost” — at the end of the 5th I told my teenage son that Yost should bring in a reliever to start the 6th otherwise the wheels are going to fall off — he thinks I am now the all-knowing baseball guru. |
| 12:59 |
: Good thing you didn’t read from my “It’s Time for the Royals to Trade James Shields” piece then!
|
| 1:00 |
What makes pulled pork “Lexington Style” |
| 1:00 |
| 1:01 |
: BBQ styles are basically all about the sauce here. Lexington style is Vinegar based but has ketchup in there too. Eastern style is just vinegar. Western style can be a few different things, including just ketchup.
|
| 1:01 |
Choosing the last player for a Wild Card roster…would you lean pitcher or position player? |
| 1:01 |
: Depends on how many of each I had, but you only really need 8 or 9 pitchers for the WC game, so probably position player.
|
| 1:02 |
Better 3b going forward: Rendon or Donaldson? |
| 1:02 |
: Rendon.
|
| 1:02 |
Wouldn’t a great pinch hitter be underrated by WAR then? Only brought in in high leverage situations, but not given extra credit for it? Not that pinch hitting specialist is going to have a very high WAR anyway. |
| 1:02 |
: Yes, but a great pinch-hitter would probably just become an ordinary regular hitter instead.
|
| 1:03 |
Do you think Trout will make the necessary adjustments, level his swing a bit, learn to hit high fastballs and return to hitting ~.320? Or is the .280-290 hitting Trout the new Trout? |
| 1:03 |
: I’m guessing his shift towards power will stay, though he might fix his up-and-in problem and cut down on the Ks somewhat.
|
| 1:04 |
Couldnt he just also learn to lay off high fastballs? |
| 1:04 |
: He had very low contact rates on high fastballs in the zone, though. Can’t lay off pitches that will be called strikes.
|
| 1:05 |
: And high fastballs that miss their spots go over the fence, so even with a high whiff rate, there is value to still chasing to some degree.
|
| 1:06 |
Craig Kimbrel had a 50 FIP- this year, about the same as Kershaw, in about 1/3 the innings, and was worth 2.2 WAR. Kershaw was worth 7.2. Wouldn’t Kimbrel, by pitching in leverage almost twice as high, extrapolate to more WAR in the same number of innings, if leverage was accounted for? |
| 1:06 |
: Pitcher WAR isn’t just FIP- multiplied by IP. Kershaw also induced 19 infield flies, which are counted as the same value as additional strikeouts, and there’s the runs-to-wins conversion as well.
|
| 1:07 |
: Looks like Kershaw’s self-created run environment gave him a 7.9 runs to wins conversion, while Kimbrel’s was 9.0.
|
| 1:08 |
Should McCutchen get extra MVP/value consideration because he played much of the final 2 months of the season with an avulsion fracture? |
| 1:08 |
: I don’t think so. It’s a performance award, and a double with a fracture isn’t more valuable than a double without one.
|
| 1:09 |
Please include infield flies in FIP or a version of FIP. Would be a more useful stat and make WAR more transparent. |
| 1:09 |
: There is literally nothing about our version of pitcher WAR which is not transparent.
|
| 1:10 |
: On the position player side of things, the only non-transparent items are UZR/UBR, which we don’t calculate ourselves.
|
| 1:10 |
“There’s no reason to judge a decision using hindsight.” — you can simultaneously say that a decision made sense at the time while accepting that it turned out poorly. |
| 1:10 |
: Of course. The second part isn’t judging the decision, though.
|
| 1:11 |
I’m really not sure you can justify saying your pitcher WAR is transparent when we had no idea there was a leverage component until recently and there’s still no mention of how it’s actually calculated in the glossary (or anywhere else I know of). |
| 1:13 |
: Neil Weinberg is systematically updating the documentation of on the glossary, and WAR is getting a big overhaul soon. We’ve made it clear numerous times over the years that leverage is included in pitcher WAR. If you feel like our documentation of that has been poor, okay, fair enough. But we’re not hiding anything.
|
| 1:14 |
Where can we see HOW leverage is included in pitcher fWAR? Honest question. |
| 1:14 |
| 1:15 |
I just don’t understand why infield flies aren’t in FIP or a FIP-like stat. Would be nice to have them in a comprehensive rate stat in addition to WAR. |
| 1:15 |
: We didn’t FIP. I think it’s poor form to take a metric that someone else created and popularized, then change the way its calculated solely on our site while keeping the name the same. Once you’ve changed the calculation, you’ve created a new stat, and should call it something else.
|
| 1:17 |
: We didn’t *invent* FIP.
|
| 1:17 |
: Okay, off to get some lunch and write about bunting.
|
| 1:17 |
: Enjoy the game tonight, everyone.

Dave is the Managing Editor of FanGraphs.
Is Fangraphs considering going from FIP to SIERRA as the main ingredient for pitcher WAR? (I asked this in the chat twice, hoping Dave sees it and gets a chance to respond if he doesn’t in the chat).
I’ve never heard any fangraphs writer say anything positive about SIERRA, always the other way
Someone asked him yesterday and he said SIERRA never even entered the discussion.
wasn’t that Jeff Sullivan that was asked yesterday? The day before the same guy asked Z and he said to ask one of the Daves.
SIERA uses a bunch of seemingly arbitrary (artificially precise?) multipliers to get the numbers “right”, doesn’t it? I’d be a bit uncomfortable with 16.986 as a multiplier or 7.653, etc. in the absence of logical explanations.
There are two reasons for the use of seemingly arbitrary multipliers:
The first is to properly weight every event. We know ERA correlates negative (as in it goes down) with K and positively with BB. However, if we want to create a formula that incorporates both, they must be weighed properly. You can’t just use BB-K as your ERA estimator, because it’s not clear that BB and K just cancel each other out. In reality, Getting 3 K is probably about as good as allowing 2 BB is bad, so the formula might start with (2BB – 3K) or something.
The second reason is to scale the formula to ERA. You might have a properly weighted formula that *correlates* with ERA, as in variation in that formula corresponds well to variation in ERA, but they may use different scales. An “average” value for unscaled SIERA may be something like 0, just based on how all the terms work out. Therefore, they add a constant and multiply the whole thing by some factor so that average SIERA is like 3.90, good is 3.40, bad is 4.40, etc.
They’ve been pretty clear about the difference between a stat for predicting value, which SIERA is, and one that measures past performance, which FIP is, so they would not make that change.
