# Name Team ESPN_POS IP FIP ERA Diff

NOTES:
FIP: Stands for Fielding Independent Pitching. FIP = ((13*HR)+(3*(BB+HBP-IBB))-(2*K))/IP + constant. The ‘constant’ is a number that gets the FIP onto the same scale as ERA. Razzball’s stat feed does not separate BB from IBB so those are not deducted. This, as well as slight differences in calculated the constant, will lead to slight differences in FIP vs. other data sources. For more info/background on FIP, see here.

FIP-ERA: In general, FIP and ERA should be close to equal with much of the difference tied to luck (HR rates, BABIP, etc.) So pitchers with a negative number are more likely to see their ERA increase while pitchers with a positive number are more likely to see their ERA decrease.

    Hi,

    The FIP vs ERA and AVG vs BABIP tools are awesome. When are they going to be updated for 2013?

    “So pitchers with a positive number are more likely to see their ERA increase while pitchers with a negative number are more likely to see their ERA decrease.”

    Is this not backwards?

    rudy, just noticed robertson not listed on here, he’s got enough qualified innings. any idea? also i’m betting if he’s missing others could be.

    • @Aubrey Plaza’s Pillow: I had a filter on there that was at about 0.33 IP per team game. So it was around 19 IP and Robertson was at 17 IP. I knocked it down to 0.25 IP per team game so Robertson shows now.

    B McCarthy ‘s xfip at 2.90 and his fip is 3.90? Why is are they so far apart? Which one is the better indicator of ros? Thanks(if you’re still answering this post)

    • @cubsin2020: The difference b/w FIP and xFIP is FIP penalizes for HRs and xFIP credits a pitcher w/ league-average HR:FB ratio. I lean towards FIP over xFIP b/c I do think HR avoidance has a lot of skill to it. But it is saying that if McCarthy could stop giving up so many HRs, has a chance to be an ownable SP (For starts other than against SD)

    Is your FIP vs. ERA lookup broken? This tool was a Godsend to me!

    is negative FIP possible or is that en error? a few guys have negative FIP’s

    • Negative FIP is possible. A single inning with 3 K’s and no base runners would be something like -3.00 FIP.

        @Rudy Gamble: wow. K-Rob is having a betances last year type year then.

            @Rudy Gamble: how often does this update, since yesterday K-Rob allowed a lot of runs (and today another one) yet he’s still at the best FIP (and he had the same number a couple of days ago). i’m guessing weekly is the answer?

            • this updates every day. i think your page might be cached. try refreshing the page. if that doesn’t work, reset your browser cache.

                @Rudy Gamble: ok, cleaned it, and K-Rob’s FIP has gone up to 2.5. what about the existence of T.wada? Or are X amount of batters faced or innings needed first?

                • The IP cutoff is 25% of Average Games Played per Team. Wada is only at 10 IP right now. The cutoff as of today is 12 IP so he should show up after his next start.

    once you start up the new 2016 one can we still access the 2015 one? i’m doing deep research (30 man league with holds, only other thing to go off is mlbdepthcharts.com for who’s doing setup duties (so far), and about to be ron shander’s book with his awesome skills research) for a bidding session that starts in Feb.

    • @goodfold2: hey goodfold – once i overwrite this for 2016, then this’ll be gone so i’d cut/paste and save it into XLS if I were you. FWIW, I have all this data archived if you really needed it.

      • goodfold2 says:

        @Rudy Gamble: do you know what date you’ll do that overwrite?

        • @goodfold2: This table doesn’t make sense to overwrite until the season starts. Should be updated soon after.

            @Rudy Gamble: i’ll be way done with the 2015 (at least concerning my bullpen research for Feb bidding) by then. sweet.

    went to look up arano and goody, and found that neither of CLE nor PHI’s RP are listed at all, do none of them have enough innings here, but that can’t be right. if this is the case for these 2 teams gotta guess it’s more than them too.
