For awhile now, I’ve had a spreadsheet that calculates park-specific Wins Above Replacement that I have wanted to implement for blog purposes…however it takes several hours of copying/pasting to utilize it which makes it slightly more inconvenient. Ben (topoftheworl)’s comment about WAR on the World Chat recently piqued my interest and I contacted him to see if he had a faster way to do the calculations. He does, but it is limited to hitters and is least prone to errors when applied to players with 150+ games in a season.
So, I have come up with the following solution: Using his quick formula to calculate WAR for players who have appeared in 150+ games in each ML season they’ve been a part of (i.e. both seasons 1 & 2 or 150+ for rookies or guys who didn’t play in S2). To compensate for the lack of park specificity with this formula, I then multiplied the result by a park factor to get a total. I know that sounds a little confusing, so here’s an example:
Pat Penny played 150+ games in both S1 & S2, making him eligible….in S1, the formula yielded a 7.31 WAR. Since he played in Cleveland (1.011 PF) I multiplied 7.31 by .989 (1-.011 because CLE’s park gives his stats a boost of .011) to get a total S1 WAR of 7.23. Following the same steps for S2, the result was 2.84 WAR, giving him a career mark of 10.07 WAR.
Below is a complete list of career WAR leaders through S2 among eligible hitters:
|Player||S1 WAR||S2 WAR||Total WAR|
|Pascual De La Rosa||3.62||2.25||5.87|
