We've always had free agency pages at the end of the year, but now I've gone back and added pages back to 1976. If you go to a league page, the graphic below shows where you can find it.

2013-2014 Free Agency Signings and Statistics - Baseball-Reference.com.

1983-1984 Free Agency Signings and Statistics - Baseball-Reference.com.

Got a request for this and it was an easy addition to make, so we now have wins above average in both the pitching and batting season finders.

2014 Atlantic League Statistics.

We are five games into the Atlantic League Season and we are updating our stats daily.

A user made the suggestion that since we had service time data why don't we add it to the player pages, so we did. It's now in the salary tables at the bottom of the player pages. This data is their service time at the start of the season and is mostly complete since 2010 opening day.

GM's may wish to double-check the numbers before entering contract negotiations. Also, if you haven't seen this area of the player page before note that you can do era adjustments to salaries and we list player contract status here.

Example: Andrew McCutchen Statistics and History - Baseball-Reference.com.

Pitching Season Finder -- - Baseball-Reference.com.

Note that we only compute blown saves for games in which we have play-by-play which is mostly complete back to 1954, but only 100% back to 1973. See our Coverage Page for all of the gaps in the data.

Save percentage is Saves / (Blown Saves + Saves).

I had wanted to put FIP next to ERA since there is often a lot of reason to want to compare them, but it's causing too much confusion for folks wanting to use ERA, so we are moving it rightward near WHIP. One thing if I have done is that if you hold your mouse over an ERA or FIP value we'll show you a little tooltip with the row's ERA, FIP and Difference all in the same output as shown below. We'll mark the difference Green when the FIP is less than ERA and red otherwise.

This will roll out sitewide over the next hour or two.

2014 Major League Baseball Rookie Players - Baseball-Reference.com.

As you know year of debut and the last year of rookie status are two different things. We have attempted to track who was a rookie in what season using the current standards and have produced a seasonal page showing those players' career stats. This data is also included in the play index, so you can search based on rookie status there as well. If you find any errors or omissions let us know.

Also on player pages we will now show the season in which we believe the player lost his rookie status.

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.

Baseball-Reference.com Front Page

We've been running transactions and injuries on the site for quite awhile now, but I've added a small module to the very bottom of the front page highlighting recent ones. Clicking on the full report links will send you to, surprise, the full report.

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.
