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

    I can't agree that it takes the guesswork out of it. WAR and Win Shares are good stats but they are not absolute and it is one person's guess work of how valuable something is. It is not a cut and dry stat like Usain Bolt's 100 meter time.

    Yes I agree that BA is the least important of the three but my point was that when OBPs and SAs are that close, the significant delta in the BA does come into play as a "tie breaker".

    Why is that? Is there some reaserach that proves that batting average is the most important portion of OPS?

      Huh? I specifically stated in the sentence you are quoting of me that BA is the least important of the OPS troica.

        Why is the batting average the tie breaker, rather than the OBP or the SLG% ?

          I really wish you would actually read my post if you are going to quote me. I said if the OBP and the Slug are close, then the significant delta in the batting average would be a tie breaker. The road OBP and Slugs are virtually a tie for Dewey and Mad Dog, however Mad Dog's batting average is significantly higher.

            So, why does the higher batting average become the tie breaker, rather than the isolated power, which Evans wins .170 to .123.

            Do you have some research that shows that batting average is a more important component of SLG% than isolated power?

              Fair question, I actually made a thread asking the same questions, have you seen it?

                Just looked at it, and it's not really clear which player is better. But what is clear is that there's no strong evidence that we should automatically prefer the higher batting average when both players are roughly equal in OBP and SLG%. Usually the higher batting average guy will use up more outs along the way, imcluding hitting into more DPs, since he puts the ball in play more often and would be less of a flyball hitter than the Evans or Thome type.

                I checked, and Madlock hit into DPs more often than Evans, including one season where Madlock led the league with 25 GIDPs.

                Evans - 10569 PA - 227 GIDPs - one every 46.6 PA
                Madlock - 7372 PA - 190 GIDPs - one every 38.8 PA
                .

                  Re: batting average being the tie-breaker

                  When two players are normalized to the same OPS, including OBP and SLG%, and one has a higher batting average than the other, that means that Player A has more base hits than Player B and Player B has more walks/hbp/etc than Player A. Since a base-runner can take more than one base from a base hit, then that means Player A has the potential to create more runs than Player B.

                  So, a normalized 280-350-420 line is more valuable than a normalized 260-350-420 line. Right?

                    That is correct given RANDOM production. The guy with the .260 average has to make up 20 points on his on base percentage with walks, AND 20 points on his slugging percentage with extra bases to make up for 20 points lower in batting average. A walk and an extra base are only worth about .7 of a single though so the .260 guy gives up 20 points in batting average but gains back about 28 points worth in other production to bring his other rates up to the level of the first guy.

                    However I have tended to find that higher batting average guys tend get slightly more run value from their walks, hits and extra bases than if they were produced randomly. Joe Morgan (for a negative example) only hit about .230 with a .350 slugging percentage in situations where a hit was much more valuable than a walk. Tony Gwynn, Rod Carew, Ichiro, Boggs all hit almost identically to their career rates with a runner on second and 2 outs.
                    There is a counterbalance to what you are saying here. You're focusing on the value of singles versus walks, and there's no doubt the single is better. So in the area of making up the BA difference in OB Pct, the BA is better. However, if BA is lower, you need more XBH, or isolated power, to make the slugging percentage equal--and those XBH are superior to the singles. If it's not a wash, it comes close to it, IMHO.

                      Maybe not. The one with more singles is more likely to be thrown out trying to stretch a hit, and is more likely to hit into DPs. He is using more outs up too.

                          That being said, not all high BA guys with low isolated discipline/power hit into lot of GIDP, Ichiro is a prime example.

                            Actually, I'm not even sure the agreement at the start of the thread that BA isn't the most important is accurate. At the very least, it depends on how one defines important. If it's the spread in BA, that may be generally true, because BA is more tightly bunched than slg % or OBP. However, BA is a vital ingredient of both stats, as OBP is mostly BA, but with walks and HBP included (among other considerations). Slg % is BA plus isolated power percentage. So BA counts twice in OPS+. Even for an extreme case, a low BA with high walk totals and lots of power type like Adam Dunn, about 65% of his OBP comes from BA, and over 45% of his slg% comes from BA. For the average player, it's more like 80% of OBP and 63% of slugging.

                              If you have two players with similar SLG then the one with the lower AVG is actually putting more runs on the board since he is being more efficient with his hits.
