Updated Baseball Fever Policy

Baseball Fever Policy

I. Purpose of this announcement:

This announcement describes the policies pertaining to the operation of Baseball Fever.

Baseball Fever is a moderated baseball message board which encourages and facilitates research and information exchange among fans of our national pastime. The intent of the Baseball Fever Policy is to ensure that Baseball Fever remains an extremely high quality, extremely low "noise" environment.

Baseball Fever is administrated by three principal administrators:
webmaster - Baseball Fever Owner
The Commissioner - Baseball Fever Administrator
Macker - Baseball Fever Administrator

And a group of forum specific super moderators. The role of the moderator is to keep Baseball Fever smoothly and to screen posts for compliance with our policy. The moderators are ALL volunteer positions, so please be patient and understanding of any delays you might experience in correspondence.

II. Comments about our policy:

Any suggestions on this policy may be made directly to the webmaster.

III. Acknowledgments:

This document was based on a similar policy used by SABR.

IV. Requirements for participation on Baseball Fever:

Participation on Baseball Fever is available to all baseball fans with a valid email address, as verified by the forum's automated system, which then in turn creates a single validated account. Multiple accounts by a single user are prohibited.

By registering, you agree to adhere to the policies outlined in this document and to conduct yourself accordingly. Abuse of the forum, by repeated failure to abide by these policies, will result in your access being blocked to the forum entirely.

V. Baseball Fever Netiquette:

Participants at Baseball Fever are required to adhere to these principles, which are outlined in this section.
a. All posts to Baseball Fever should be written in clear, concise English, with proper grammar and accurate spelling. The use of abbreviations should be kept to a minimum; when abbreviation is necessary, they should be either well-known (such as etc.), or explained on their first use in your post.

b. Conciseness is a key attribute of a good post.

c. Quote only the portion of a post to which you are responding.

d. Standard capitalization and punctuation make a large difference in the readability of a post. TYPING IN ALL CAPITALS is considered to be "shouting"; it is a good practice to limit use of all capitals to words which you wish to emphasize.

e. It is our policy NOT to transmit any defamatory or illegal materials.

f. Personal attacks of any type against Baseball Fever readers will not be tolerated. In these instances the post will be copied by a moderator and/or administrator, deleted from the site, then sent to the member who made the personal attack via a Private Message (PM) along with a single warning. Members who choose to not listen and continue personal attacks will be banned from the site.

g. It is important to remember that many contextual clues available in face-to-face discussion, such as tone of voice and facial expression, are lost in the electronic forum. As a poster, try to be alert for phrasing that might be misinterpreted by your audience to be offensive; as a reader, remember to give the benefit of the doubt and not to take umbrage too easily. There are many instances in which a particular choice of words or phrasing can come across as being a personal attack where none was intended.

h. The netiquette described above (a-g) often uses the term "posts", but applies equally to Private Messages.

VI. Baseball Fever User Signature Policy

A signature is a piece of text that some members may care to have inserted at the end of ALL of their posts, a little like the closing of a letter. You can set and / or change your signature by editing your profile in the UserCP. Since it is visible on ALL your posts, the following policy must be adhered to:

Signature Composition
Font size limit: No larger than size 2 (This policy is a size 2)
Style: Bold and italics are permissible
Character limit: No more than 500 total characters
Lines: No more than 4 lines
Colors: Most colors are permissible, but those which are hard to discern against the gray background (yellow, white, pale gray) should be avoided
Images/Graphics: Allowed, but nothing larger than 20k and Content rules must be followed

Signature Content
No advertising is permitted
Nothing political or religious
Nothing obscene, vulgar, defamatory or derogatory
Links to personal blogs/websites are permissible - with the webmaster's written consent
A Link to your Baseball Fever Blog does not require written consent and is recommended
Quotes must be attributed. Non-baseball quotes are permissible as long as they are not religious or political

Please adhere to these rules when you create your signature. Failure to do so will result in a request to comply by a moderator. If you do not comply within a reasonable amount of time, the signature will be removed and / or edited by an Administrator. Baseball Fever reserves the right to edit and / or remove any or all of your signature line at any time without contacting the account holder.

VII. Appropriate and inappropriate topics for Baseball Fever:

Most concisely, the test for whether a post is appropriate for Baseball Fever is: "Does this message discuss our national pastime in an interesting manner?" This post can be direct or indirect: posing a question, asking for assistance, providing raw data or citations, or discussing and constructively critiquing existing posts. In general, a broad interpretation of "baseball related" is used.

Baseball Fever is not a promotional environment. Advertising of products, web sites, etc., whether for profit or not-for-profit, is not permitted. At the webmaster's discretion, brief one-time announcements for products or services of legitimate baseball interest and usefulness may be allowed. If advertising is posted to the site it will be copied by a moderator and/or administrator, deleted from the site, then sent to the member who made the post via a Private Message (PM) along with a single warning. Members who choose to not listen and continue advertising will be banned from the site. If the advertising is spam-related, pornography-based, or a "visit-my-site" type post / private message, no warning at all will be provided, and the member will be banned immediately without a warning.

It is considered appropriate to post a URL to a page which specifically and directly answers a question posted on the list (for example, it would be permissible to post a link to a page containing home-road splits, even on a site which has advertising or other commercial content; however, it would not be appropriate to post the URL of the main page of the site). The site reserves the right to limit the frequency of such announcements by any individual or group.

In keeping with our test for a proper topic, posting to Baseball Fever should be treated as if you truly do care. This includes posting information that is, to the best of your knowledge, complete and accurate at the time you post. Any errors or ambiguities you catch later should be acknowledged and corrected in the thread, since Baseball Fever is sometimes considered to be a valuable reference for research information.

VIII. Role of the moderator:

When a post is submitted to Baseball Fever, it is forwarded by the server automatically and seen immediately. The moderator may:
a. Leave the thread exactly like it was submitted. This is the case 95% of the time.

b. Immediately delete the thread as inappropriate for Baseball Fever. Examples include advertising, personal attacks, or spam. This is the case 1% of the time.

c. Move the thread. If a member makes a post about the Marlins in the Yankees forum it will be moved to the appropriate forum. This is the case 3% of the time.

d. Edit the message due to an inappropriate item. This is the case 1% of the time. There have been new users who will make a wonderful post, then add to their signature line (where your name / handle appears) a tagline that is a pure advertisement. This tagline will be removed, a note will be left in the message so he/she is aware of the edit, and personal contact will be made to the poster telling them what has been edited and what actions need to be taken to prevent further edits.

The moderators perform no checks on posts to verify factual or logical accuracy. While he/she may point out gross errors in factual data in replies to the thread, the moderator does not act as an "accuracy" editor. Also moderation is not a vehicle for censorship of individuals and/or opinions, and the moderator's decisions should not be taken personally.

IX. Legal aspects of participation in Baseball Fever:

By submitting a post to Baseball Fever, you grant Baseball Fever permission to distribute your message to the forum. Other rights pertaining to the post remain with the ORIGINAL author, and you may not redistribute or retransmit any posts by any others, in whole or in part, without the express consent of the original author.

The messages appearing on Baseball Fever contain the opinions and views of their respective authors and are not necessarily those of Baseball Fever, or of the Baseball Almanac family of sites.

Sincerely,

Sean Holtz, Webmaster of Baseball Almanac & Baseball Fever

    This shows differences in Dimaggio's production at home versus all players in their home park, and with their home offensive setting put at the league average, and his road production versus all players on the road.

    In other words, when road OPS+ is higher than home OPS+ it strongly suggests that the player SPECIFICALLY benefitted in relative production from his home park. It cancels out effects that a park has on ALL players such as Coors field just boosting offense as a whole.

    I have also removed pitchers to make it consistent with OPS+ total. The only things it doesn't do is account for a player not having to hit in their home park on the road, and not facing their own pitching staff.



    Code:
    Road Pas	Road sOPS+	PAxsOPS+
    362	        163	                59006

    289	        221	                63869
    346	        186	                64356
    284	        192	                54528
    282	        155	                43710
    340	        189	                64260
    173	        213	                36849
    328	        196	                64288
    217	        125	                27125
    
                    3858	                 712138
    712138/3858=184.6 Career road sOPS+ including pitchers

    League OPS+ with pitchers is 94 in his seasons so to remove pitchers multiply his OPS+ by .94 to get:

    173.51 sOPS+

    His overall was 155 so to get the home sOPS+ take 155 x 2 minus 173.5 to get 136.49

    So Dimaggio had a 173.5 road relative OPS+ and a 136.5 home OPS+. Technically we should round them both to the 1s place, which would be 174 and 136. Quite telling of what his park did.
    Is it .94? I get a better fit with the data using .92. The adjustment isn't a constant is it? Wouldn't it vary over time with pitchers worse today, and better hitters back then?

    Also, since I am using the data, it's a small thing but the 1947 road PA was 307.

      Yes. Any issues somebody has with how WAR deals with position, defense, ANYTHING will be the same issues with WAA. The ONLY difference is the comparison baseline. ONLY. . You can take the same formula and compare to any baseline you want to. Wins Above Good. Wins Above All Star. Wins Above Cobb. Whatever you want.

        League OPS+ file.....

        Brett, you weren't kiddin' about the league OPS+ not changin' much. Just seems like it's not fully accounting for run environment. Heck, the '68 NL is the same as '28 NL.

        Can we use something like innings pitched per earned run instead? Looking at that, 1968 would show to have 3.01 IP/ER and 1928 NL would be 2.25 IP/ER. Just a thought.

          OPS+ is set at 100 each season. the only problem is that sOPS+ keeps pitchers in the league numbers, but traditionally we take pitchers out. The .94 just takes them back out. The .94 should not change because of run environment, it just says that removing pitchers raises the league production by about 6% per plate appearance. It is only a measure of pitchers batting effect on hitting, not run setting.

            Just like there's different levels of position hitters, there's different levels of hitting pitchers. Some get bunts down more often, move runners along, put the ball in play more often, etc...but you know that.

            So..its' fine to remove pitchers. Shouldn't there be a step AFTER that though? Let's remove pitchers, and THEN adjust to run environment. There's no reason why the 1927 AL should have the same league OPS+ as the '59 and '60 AL.

              Sultan, OPS+ has already been adjusted to the league run environment. Ruth's road sOPS+ scores, and overall OPS+ has already been done relative to run environment. Same with someone in 1968. The 93, 94, 95 is the effect of pitchers, and yes it is a little different from year to year.

                If it's already been fully adjusted, then why do we constantly see people still adjusting for era? They adjust even after seeing these numbers that are already adjusted. I'm trying to get to a place where we've adjusted all the way, and then some.

                    And I am sure the subtraction would be doubled if the player was a first baseman.
                    Your Second Base Coach
                    Garvey, Lopes, Russell, and Cey started 833 times and the Dodgers went 498-335, for a .598 winning percentage. That’s equal to a team going 97-65 over a season. On those occasions when at least one of them missed his start, the Dodgers were 306-267-1, which is a .534 clip. That works out to a team going 87-75. So having all four of them added 10 wins to the Dodgers per year.

                      So, I have the PA, HR and sOPS+ H/A split data for most of the RH batters for 1936-51 for the Yankees. (I only tabulated for position players with 100+ PA in a season.) A few pitcher seasons (Chandler and Ruffing) were left off plus all the RH seasons where a batter had less than 100 PA. There was one player in 1950 who split time with the Yanks and someone else, and with just ~160 PA, I just left him off.

                      Code:
                      Home                    
                                   PA   HR   sOPS+  
                      DiMaggio    3,790 148  141.6       
                      All other  16,047 234   97.4


                      Code:
                      Away                    
                                   PA    HR   sOPS+  
                      DiMaggio    3,883  213  171.5       
                      All other  17,322  307  104.1

                      What I noticed were two things:

                      1) YS did not hurt "all other" RH hitters for HR as much as Joe D. While "all other" hit 31% more total HR on the road, Joe D was at 44%. However, batters on winning teams, usually bat more on the road, so totals are misleading. In fact, once you adjust for the H/A splits in PA, "All other" averaged 21.5% more HR per PA on the road (68.6 vs 56.4), but Joe D averaged 40.5% more (25.6 vs 18.2)

                      2) YS did not have anywhere near the OPS+ impact on "all other" as on DiMaggio. "All other" was 6.8% better on the road, but Joe D was 21.1% better.


                      This leads to more questions of course. Why was DiMaggio in particular hurt while others were hurt far less? Were others making adjustments? Was YS only hurting one type of hitter? (Joe Gordon, a legitimate RH power hitter, had a road HR rate per PA that was only 8.6% higher than his YS rate----28.8 vs 26.5----so he was affected even less than the remainder of the "All Other" group.)


                      As a note, I examined the 1940-42 splits and it looks more like a .93 adjustment for pitchers. Also, I have a correction of the 1947 road PAs.

Was YS only hurting one type of hitter? (Joe Gordon, a legitimate RH power hitter, had a road HR rate per PA that was only 8.6% higher than his YS rate----28.8 vs 26.5----so he was affected even less than the remainder of the "All Other" group.)


                        As a note, I examined the 1940-42 splits and it looks more like a .93 adjustment for pitchers. Also, I have a correction of the 1947 road PAs.

                        That is interesting, but also keep in mind that since home runs make up a larger percentage of Dimaggio's OPS+, it can effect his OPS+ even more. If a 30 home run guy is reduced to 24 its a greater affect than if a 10 home run guy is reduced to 8. Also, Dimaggio hit a LOT more triples at home, so it looks to me like he was having a margin of his home runs removed based on distance breakdowns and not necessarily on approach (at least as much). If we had the average guys as a group hitting a few IPHRs over the outfielders head, while perhaps they just played deeper on Dimaggio, it could matter.

                        Do you have any idea how many of the home runs hit in YS were IPHRs also?

                          There is no breakdown on BBRef for IPHR by season, and a lot of the players split time with other teams. But if you allocate their career IPHR as a proportion based upon the % of HR hit at home in 1936-51 in my list to total HR hit in their career, it adds up to 13 YS IPHR by the "all other" group.

                          There's another way to do it of course. What is the most possible if YS created an insane amount more than any other stadium?

                          a) Lazzeri hit 8 IPHR, but he hit 98% of his HR as a Yankee. Allocating 1 to him makes sense since 1936-37 was about 1/8th of all his Yankee HR.
                          b) Bauer hit 7 IPHR, but he hit 96% of his HR as a Yankee. Allocating no more than 2 to him makes sense since 1949-51 was about 1/5th of all his Yankee HR.
                          c) Chapman had 15 IPHR, but he only hit 1 HR as a Yankee in YS, so the most he could have is 1.
                          d) Let's make all of Crosetti's career IPHR at YS, so that's 4.
                          e) Let's do the same for Powell (1), Glenn (1), Dahlgren (3), Gordon (1), Steinweiss (2), Hemsley (1). Total is 9.

                          So the most it could probably be is 17. So the total IPHR by RH at YS in 1936-51 (excluding DiMaggio) is probably in the 13-17 range. So that is 7% of all the HR not hit by DiMaggio in 1936-51.

                          If you take Dimaggio's 3 IPHR and assume all were at YS, and add that to half of his "extra" triples, you get 3+8, or 11. If all those "would" have been IPHR, you get 11 IPHR, and then 148+8 HR at YS. In that case, 11/156 is 7%. So, although perhaps coincidental, it's possible that either a faster runner, or a less deep outfielder could have matched the same IPHR rate.

                          There's a speed factor as well, since depending on actual raw speed, one player might get farther than another player, even if the ball went just as far over an outfielder's head.

                          Until we get location data for players in that period, there's no way to know if players changed their approach.

                            I was curious to see how this sOPS+ thing would handle Piazza, who has a 91 to 108 home/road tOPS.

                            The home/road edge is significantly reduced. Guess you were right Brett, when you said tOPS has serious flaws.

                            If the expected home advantage here is 2% (or whatever it is), then how do we handle a 3.71% road edge?

                              Did you mean, benefitted from the road parks?
