Replacement Value

There’s a new section in the batting player pages which does the job of calculating a player’s runs over replacement and wins over replacement. Major thanks goes to Dave Cameron, Sean Smith, and Tangotiger for instructing me on the best way to do this.

Under each “Value” section you’ll find:

Batting – wRAA (Runs Above Average) with a park adjustment.
Fielding – The sum of a player’s UZR.
Replacement – The replacement level adjustment set at 20 Runs / 600 PA.
Positional – The positional adjustment set using Tangotiger’s values (see this link)
Value Runs – The sum of Batting, Fielding, Replacement, and Positional.
Value Wins – Value Runs converted to a wins scale.
Dollars – Value Wins converted to the following dollar scale:

2002 – $2.6m / win
2003 – $2.8m / win
2004 – $3.1m / win
2005 – $3.4m / win
2006 – $3.7m / win
2007 – $4.1m / win
2008 – $4.5m / win

This will all eventually be in the leaderboards and team pages, probably later this week.
