Box Scores – web 1.0? Thats’s the case according to this recent Fortune Magazine article.

The replacement is the Winning Probabilty Added graph or WPA. From the Kansas City Star:

The concept of WPA has been around for almost 40 years. But the stat caught fire on the Web after the publication of last year’s The Book: Playing the Percentages in Baseball by sabermetricians Tom Tango, Mitchel Lichtman and Andrew Dolphin. The WE values currently in vogue were established in that book.

David Appelman, owner and Web master of FanGraphs.com, seized upon the WPA framework and incorporated it into his site, where you can find WPA statistics for every player, every team and every game. And you can look at these (and a lot more) both in numerical format or on easy-to-read graphs.

“What’s great about WPA,” Appelman said, “is that after the game you can quantify a player’s contribution to the win or loss.
