FanGraphs Adds WAR data
Merry Christmas everyone – as a Christmas present to baseball fans everywhere, David Appelman has added Wins Above Replacement data to all the player pages for every hitter in baseball. Not only that, but we’ve incorporated the per-year marginal Win/$ rate that MLB teams paid to acquire players in order to calculate a player’s true dollar value for each season going back to 2002.
I would say with all kinds of confidence that the Total Value Wins and the Dollar Valuations on FanGraphs are now the most accurate single number metric of player value available anywhere online. An example of how these can be used.
Adrian Beltre, since joining the Mariners:
2005: +2.4 wins, $8 million value
2006: +4.8 wins, $17.8 million value
2007: +2.7 wins, $10.9 million value
2008: +4.1 wins, $18.3 million value
Over those four years that Beltre has been a Mariner, he’s been worth $55 million. He has been paid $52 million. The contract has returned a net value of about $3 million so far, and obviously, Beltre is a pretty valuable asset at the moment. There is no way – none – to describe the Beltre signing as anything other than a success. It’s been a good deal for the Mariners in total, and it continues to be a great deal for them going forward.
Anyway, I’d encourage you to check out the FanGraphs player pages to see how much each player contributes in terms of wins and dollars. And don’t worry, this data will be up on the team pages and leaderboards shortly, and yes, we’ll be adding win values for pitchers too.
