Calculating Defensive Ratings

RULE: For the 2010 season, the Commissioner will determine opening day defensive ratings by averaging APBA ratings for 2009 and a selection of at least three defensive metrics that determine a player’s value in terms of runs allowed or games won/lost. For seasons beginning in 2011, the APBA ratings will be dropped from these calculations. As the season progresses, the Commissioner will periodically update defense ratings by using metrics of the players’ performance during the season. If a player has no defensive rating from the previous year at a position, he receives the replacement rating at his first appearance at that position, as follows: C: 6.0; 1b: 2.0; 2b: 6.0; ss: 7.0; 3b: 3.0; of: 1.0. A player with no defensive ratings at all receives a replacement rating at the position the Commissioner determines is his main defensive position.
