Fielding Independent Pitching (FIP) added to Baseball-Reference.com

Posted by sean on April 17, 2014

Last night, I added FIP (short for Fielding Independent Pitching) to the site. This is a sabermetric stat for pitchers that approximates ERA without the effect of their team's fielding ability. FIP actually correlates to future ERA better than ERA itself making it a superior indicator of future performance.

The idea is that the pitcher most directly controls the number of walks, home runs and strikeouts that occur and that the batters and fielders have a bigger say on whether balls in play are turned into outs and that most pitchers' Batting Average on Balls in Play (BAbip) reverts to a league average from one year to the next.

FIP is (13*HR + 3*(BB+HBP) - 2*SO)/IP + Constant(year). The constant is set so the yearly avg FIP equals the yearly avg ERA.

FIP can be looked at exactly like ERA and is scaled to exactly the same league average as ERA, but it's range will be slightly smaller.

Often a player with a low FIP and high ERA will improve, while a low ERA and high FIP indicates a likely regression as more hits start falling. I've placed FIP next to ERA to make this comparison more obvious, but if it begins making the ERA lookup too hard, I may move it further right on the pitching tables.

I've also added FIP and K% to the Play Index Season Finder. Right now, I don't believe we will add xFIP given the inconsistency in batted ball data, but that could change.

Player with big gap in FIP and ERA: Ricky Nolasco.

Age Relative to League Added to Minors Player Pages – Baseball-Reference.com

Posted by sean on April 15, 2014

Example: Jesse Biddle Minor League Statistics & History - Baseball-Reference.com.

We've had the league ages available for a long time now, but a user feature request pointed out to me that it would be useful to have this on the actual player pages as age is probably a prospect's most important stat.

You'll see the difference between their age and the league avg right next to the column with their age.

Manager & Umpire Challenges Added To Baseball-Reference.com

Posted by sean on April 11, 2014

Baseball-Reference.com - MLB Stats, Standings, Scores, History.

On the front page of the site, we now give a running total of the number of plays challenged along with links to the team-by-team totals and also to the manager pages.

challenges

On the Manager pages, we actually show the details of each challenge along with the scoring change (if appeal is successful) and leverage prior to the play. It would be nice to show the WPA change when there is a successful challenge, but our system would just take too many modifications at the moment to implement that quickly.
